Every timing belt application is different; there&#;s no cookie cutter selection model to follow. Timing belt solutions need to be determined on a case-by-case basis. And, in order to select the most efficient belt for your plant, you&#;ll want an expert&#;s opinion on the matter. That&#;s why the professionals at Accurate Industrial created this article: to guide you through answers to our most commonly asked timing belt questions.

Timing belt frequently asked questions:

1. How do I know when I need a truly endless belt vs. a welded endless belt?

• To answer this question, we will need to know what your timing belt is being used for. If your application requires the belt to transmit power, you will need a truly endless belt.
• Welded endless belts are fine for more common conveying applications. They carry components, ingredients, finished products, cartons, etc. on top of the belt. The &#;timing&#; in timing belt indicates they are employed mostly to synchronize delivery of these goods in the production, packaging, or freight-loading process.

2. What cord type should I use?

• Again, different cord types are designed for different applications. Steel is typically the tensile cord material of choice, especially in power-transmission applications. It provides the highest tooth shear strength of any cord material.
• Kevlar cord is an effective alternative and is often used in metal detecting applications and when steel does not offer sufficient impact resistance for items dropped onto the belt. Kevlar CANNOT be used in wet or humid environments, cords constructed with aramid fibers absorb moisture, causing them to stretch and contract. These changes in fiber length can cause problems in belt performance, such as slippage and binding, altering the engagement between belt and sprocket teeth.

3. What is PAZ/PAR and why do I need it?

• PAZ/PAR are nylon fabric coverings that are molded to either to the back (PAR) or the tooth side (PAZ) of timing belts. The nylon facings reduce the coefficient of friction on both sides. PAZ, optimizes the interactions between the timing belt teeth and the pulley. Less friction will result in quieter belt operation and longer tooth life. PAR reduces friction between the timing belt and the product being conveyed. This functionality is especially key in accumulating applications and when easy product release from the belt speeds the operation.

4. What are the advantages and disadvantages of a pin splice?

• Pin splicing allows belts to be removed from and installed onto the conveyor without disassembling the machine. Pin-spliced belts can be replaced in as little as 10 minutes. This can save as much as eight hours and some cases days of valuable production time.
• However, pin splicing reduces the timing belt&#;s tensile strength, preventing its use in power-transmission applications. (Note: welded endless belts are about half as strong as truly endless belts; pin-spliced belts are about half as strong as welded).

5. What is the difference between a molded cover and a spliced cover?

• Molded covers offer superior performance, 9 times out of 10 when there is failure it is at the splice location. Molded covers are continuous; they contain no seams that can fray or catch, causing failure after repeated use. The chemical properties of some rubbers and some other materials are not conducive to molded covers and can only be applied with spiced covers. One disadvantage of molded covers is the lead time. Manufacture and delivery of these belts can take 4 to 6 weeks.

6. How do I find out my timing belt&#;s tooth style?

• The best way to determine the tooth style of your belt is by using a timing belt tooth gauge; contact Accurate Industrial for your free gauge.
• If you do not have a tooth gauge, you can determine the tooth style by observing tooth shape (rounded or trapezoidal) and measuring the pitch of the teeth (the distance between the centers of two adjacent teeth).

7. What type of cover (also referred to as backing) is best for my application?

• For a full discussion of this topic and a comparison of all timing belt cover options, visit https://accurateindustrial.com/products/timing-drive-belts/timing-conveyor-belts/.
• Use this guide to determine the cover/backing type that will work best for you:

A Helpful Guide to Conveyor Belts for Various Industries

Conveyor belts have long been the heart of modern manufacturing, logistics, and distribution. From speeding up product handling to improving workplace safety, these systems help companies in every industry streamline their operations. If you&#;ve ever wondered which conveyor might suit your business needs&#;or if you just want to learn more about the incredible variety of conveyor technologies available&#;this guide is for you.

Below, we&#;ll explore why conveyor belts are so essential, highlight different types of conveyor systems, and dive into industry-specific requirements.

Why Conveyor Belts Are Essential Across Industries

Conveyor belts serve as the backbone of material transport in an array of industries&#;from food processing and pharmaceutical manufacturing to automotive assembly and e-commerce fulfillment. Their primary role is to move products in an efficient, consistent manner, replacing or reducing manual labor and minimizing the risk of human error.

The benefits of using conveyor belts are numerous and include:

• Reduced Labor Costs: By automating the movement of goods, facilities can reduce manual handling tasks and reallocate labor elsewhere.
• Improved Safety: Fewer repetitive tasks and heavy lifting requirements mean fewer worker injuries.
• Greater Throughput: Conveyors can operate around the clock with minimal downtime, pushing more product through your facility in less time.
• Consistent Quality Control: A well-designed conveyor can help maintain product integrity from start to finish.

Key Conveyor Types & Their Applications

When it comes to conveyor systems, one size does not fit all. Different environments and products require different levels of durability, hygiene, load capacity, and design flexibility. Below are some of the most common conveyor types you&#;ll find&#;and how each can be applied in various industries.

Sanitary Conveyors

Sanitary conveyors take cleanliness to the next level, featuring stainless steel frames, FDA-approved belting, and fast, thorough washdown designs. They&#;re critical in food, pharmaceutical, and cosmetic environments where hygiene and regulatory compliance (BISSC, NSF, USDA, FDA) are key.

• Tool-less disassembly saves time during cleaning.
• Welded stainless-steel frames reduce bacterial harborage points.
• FDA-approved belting and plastic components

These conveyors ensure products like baked goods, meat and poultry, or ready-to-eat items remain contamination-free, making them ideal for the food handling industry.

Pallet Systems

Pallet systems specialize in precise product positioning and the ability to integrate sensors and Industry 4.0 technology . They often utilize dual timing belts or edge roller technology (ERT) to move pallets gently and accurately, great for automated and robotic production lines.

• ± 0.5 mm product placement accuracy.
• Pin tracking for simple, cost-effective navigation of corners.
• Cleanroom-rated options (ERT) for dust-sensitive processes like electronics or medical devices.

Whether you&#;re assembling electronics, inspecting automotive components, or indexing products for testing, pallet system conveyors help keep products aligned and on track.

Flexible Chain Conveyors

Flexible chain conveyors (like Dorner&#;s FlexMove line) easily navigate curves, inclines, and declines, saving valuable floor space and simplifying complex layouts. They&#;re a go-to choice in packaging, e-commerce, and integrator applications where product lines often merge, divert, and change elevation.

• Plastic chain belts come with friction inserts, rollers, or cleats.
• Modular design means you can quickly reconfigure to meet new production goals.
• Aluminum or stainless frames handle diverse environments, from dry to light washdown.

Aluminum & Stainless Frame Belted Conveyors

For general manufacturing needs, aluminum-frame conveyors offer durability in a lightweight package. Stainless steel frames, on the other hand, provide extra corrosion resistance for harsh or damp environments.

• Low-profile designs integrate easily with existing machinery.
• Cleated belts manage inclines and declines efficiently.
• Heavy-duty options (like DCMove or the series) handle large loads in industrial settings.

A Closer Look at Conveyor Belt Types

Beyond the frame style and overall conveyor design, belt choice is equally crucial. Dorner offers fabric conveyor belts, modular conveyor belts, and flexible chain conveyor belts&#;each with specific advantages and application niches.

Fabric Conveyor Belts

Fabric belts feature multiple layers, including a strength layer (often polyester or nylon) and various cover materials (like PVC, TPU, or silicone). They&#;re typically low-profile and support smaller pulley diameters, making them ideal for tighter spaces or more precise product handling.

• Woven or nonwoven designs.
• Suitable for automation, material handling, and FDA food processing (when the right cover material is chosen).
• Can be customized for high- or low-temperature applications.

Modular Conveyor Belts

If you need easy cleaning, robust durability, or the ability to handle open-surface tasks like draining, cooling, or spraying, consider modular conveyor belts:

• Excellent for bakery, dairy, and medical processes where cleaning is frequent.

Flexible Chain Conveyor Belts

Flexible chain belts excel in complex layouts with multiple curves, inclines, and declines within one conveyor run:

• Open belt sides allow the chain&#;s knuckle to move down the center track.
• Often used in manufacturing, bottling, secondary packaging, and automation lines.
• Compatible with AquaGard Series and Dorner&#;s FlexMove platform.

Industry-Specific Conveyor Considerations

Each industry has its own unique challenges and regulations. Choosing the right conveyor means balancing cost, efficiency, sanitation, and compliance&#;and a one-size-fits-all approach rarely works.

Food Processing & Handling

Food-grade conveyors must resist bacteria build-up and handle daily, often rigorous washdowns. Sanitary conveyors with removable wear strips, minimal horizontal surfaces, and quick belt removal features enable frequent and thorough cleaning&#;critical for maintaining safety and preventing contamination.

Consumer Packaged Goods (CPG)

From home goods and cleaning products to cosmetics, CPG lines often juggle multiple SKUs on a single production line. Conveyors that allow rapid changeovers, simple merges, and effective packaging inspection stations help keep throughput high and downtime low.

Material Handling & Industrial

Industrial environments can be tough&#;conveyors often face heavy loads, dust, or abrasive conditions. Robust frames, powerful motors, and pallet systems are often favored in metalworking, automotive, or machine tool shops, ensuring conveyors withstand continuous, demanding operations while offering a high rate of accuracy and repeatability.

Medical & Pharmaceutical

When it comes to medical devices or pharmaceutical products, cleanliness, traceability, and gentle handling are paramount. Belt-free rollers or cleanroom-rated conveyors, such as Dorner&#;s ERT series, minimize product contact points and adhere to stringent FDA and GMP guidelines.

E-Commerce & Packaging

For high-volume shipping and fulfillment centers, speed and accuracy are everything. Flexible chain conveyors can accommodate multiple merges and diverts in a limited footprint, while robust scanning and labeling systems integrate seamlessly for error-free order fulfillment.

Automation & Integrators

System integrators often seek conveyors that easily connect to robotic arms, sensors, PLCs, or vision systems. Pallet systems with precision indexing or flexible chain conveyors with modular construction are ideal for creating automated assembly and packaging lines that can adapt to rapid changes.

Designing Your Conveyor Solution

Selecting the right conveyor system starts with analyzing production requirements, space constraints, and product characteristics. Consider factors like the product&#;s weight, size, and fragility. Ask questions about sanitation requirements, environment (e.g., washdown vs. dry), and potential for future expansions.

Begin your design process by:

1. Identifying Production Goals: Throughput, level of automation, and floor space.
