Cylindrical roller such roller is mainly used for cylindrical roller bearings, roller assembly can also be directly used in machinery. That kind of roller has been standardized in s ize, can be used as a commodities roller for the design and user-selected.roller bearing

(2) long cylindrical roller divided shaft diameter and shaft diameter in two class roller, mainly used for long cylindrical roller bearings, roller assembly can also be directly used in machinery.

3 needle roller such is mainly used for needle roller bearings, the gimbal needle roller bearings and thrust needle roller bearings, needle roller assembly can also be directly used in machinery. That kind of roller has been serialized in size for the design choices. According to the needs of the bearing structure, cone-shaped needle at both ends of the shape of the head, flat head-shaped, round-shaped.

4 tapered roller circular truncated cone, the cone angle is typically 1 ° to 4 ° 20 , there is less than 1 ° or greater than 4 ° 20 , for 2 °. The roller length generally does not exceed twice the diameter of roller big-endian. This type of roller used for tapered roller bearings, roller basically used for large cone angle thrust tapered roller bearings.

5. Spherical roller roller raceway spherical shape. With this roller bearings with self-aligning performance, can withstand great loads. Spherical roller stars asymmetric and symmetric shape Usually asymmetric spherical end face, the two ends of the symmetrical surface of the flat faces. Symmetrical spherical roller better performance, rather than the symmetrical phase-out form. Such roller for self-aligning roller bearings and spherical roller thrust bearings.spherical roller bearing

The spiral roller is a special section steel strip coils made of hollow roller, divided both left and right hand. This roller application is not very extensive, mainly used by the impact load spiral roller bearings.

7 pillars hole roller pillar ho les roller center with through hole, this hole is used to hold pillar, in order to fix the sheet pillars cage. Class roller cylindrical, conical, spherical shape, mainly used for large bearings.
