There are many types of rollers: cylindrical rollers, long cylindrical rollers, needle rollers, tapered rollers, spherical rollers, spiral rollers, support hole rollers.

1. This kind of roller is mainly used in bearing roller factory, but also can be directly used in the roller assembly in machinery.This kind of roller has been standardized in size and can be used as a commodity roller for design and user choice.

2. Long cylindrical roller this kind of roller is divided into two kinds of shaft and diameter and without shaft and diameter, mainly used in long cylindrical bearing roller factory, can also be directly used in the roller assembly in machinery.

3. Needle roller this kind of roller is mainly used for INA needle bearings, universal joint needle bearings and thrust needle bearings, but also can be directly used in the needle assembly in machinery.This kind of roller has been serialized in size for design selection.According to the needs of bearing structure, the head shape of both ends of needle rolling has cone head, flat head, round head and so on.

4. The cone roller is a circular truncated cone, and its cone Angle is usually 1° -- 4°20 ', but also less than 1° or greater than 4°20 ', most of which is 2°.The roller length is generally not more than two times the diameter of the large end of the roller.This kind of roller is mostly used in bearing roller factory. The rollers with large cone Angle are basically used in thrust tapered roller bearings.

5. Spherical roller The rolling surface of a roller is spherical.The bearing with this kind of roller has the performance of automatic self-aligning and can bear a large load.Spherical rollers can be divided into asymmetric and symmetrical types. Generally, the large end face of the asymmetric type is spherical, and the two end faces of the symmetric type are flat.The performance of symmetric spherical roller is better, while the non-symmetric roller is eliminated.This kind of roller is used for self-aligning roller bearings and thrust self-aligning roller bearings.

6. Spiral roller it is a hollow roller made of steel strip with special section, which is divided into two kinds: left-handed and right-handed.This roller is not widely used, mainly used for impact load bearing roller factory.

7. Pillar hole roller Pillar hole roller with a through hole in the center, the hole is used to install the pillar, so as to be fixed on the sheet pillar holding frame.This kind of roller has cylindrical, conical, spherical shape, mainly used for extra-large bearings.
