Simply because the the tapers have so much metal carrying load over long/wide rollers, they have a HUGE capacity for load. Just because a tapered roller has high radial capacity does not make it unilaterally better/best for any specific application, especially axial thrust in ball screws.

Design :

Cylindrical roller bearings come in a wide variety of designs. The most common is the single-row cylindrical roller bearing with a cage. This design is able to support high radial loads and very high speeds.

There are also cylindrical full complement cylindrical roller bearings, which have no cage and can accommodate a maximum number of rollers. As a result, they offer very high load capacity and rigidity. However, their composition considerably reduces rotation speed, and they are only suitable for unidirectional axial loads.

The high-precision cylindrical roller bearing is used to radially support the main spindles of machine tools. The entire bearing can be disassembled for easy assembly. What's more, the inner ring features a tapered bore that facilitates radial clearance adjustment.

Advantages :

Performance and design explain why cylindrical roller bearings are suitable for specific applications. They offer a variety of advantages, including the following:

• It has greater fatigue and shock resistance than a ball bearing.

• Its unique design makes it easy to assemble and disassemble.

• It is designed to support combined radial load (N and NU type) and axial load (NJ and NUP type).

Applications :

Cylindrical roller bearings are mainly used in various equipment such as electric motors, axleboxes, pressure rollers and rolling mill rolls due to its ability to support high radial loads. They are also extremely effective in applications requiring gear and transmission changes.
