Classification of bearing rollers
Core Tips: 1. Cylindrical Roller This type of roller is mainly used for cylindrical roller bearings, and the roller assembly can also be used directly in machinery. This type of roller has been standardized in size and can be used as a commercial roller for design.
1. Cylindrical Roller This type of roller is mainly used for cylindrical roller bearings, and the roller assembly can also be used directly in machinery. This type of roller has been standardized in size and can be used as a commercial roller for design and user selection. 2. Long cylindrical roller This type of roller has two types of shaft diameter and no shaft diameter. It is mainly used for long cylindrical roller bearings, and the roller assembly can be directly used in machinery. 3. Needle roller This type of roller is mainly used for needle roller bearings, universal joint needle roller bearings and thrust needle roller bearings, and the needle roller assembly can be directly used in machinery. This type of roller has been serialized in size for design choice. According to the needs of the bearing structure, the heads of the needle ends have a conical shape, a flat head shape, a round head shape and the like. 4. Tapered roller is a circular cone with a cone angle of usually 1 ° ~ 4 ° 20 ', but also less than 1 ° or greater than 4 ° 20 ', mostly 2 °. The roller length is generally not more than twice the diameter of the large end of the roller. This type of roller is mostly used for tapered roller bearings, and the roller with large cone angle is basically used for thrust tapered roller bearings. 5. Spherical roller The rolling surface of the roller is spherical. Bearings with this type of roller have self-aligning properties and can withstand large loads. The spherical roller is divided into an asymmetric type and a symmetrical shape. Generally, the large asymmetric end face is a spherical surface, and the symmetric end faces are flat end faces. Symmetrical spherical rollers perform better, while non-symmetrical ones are obsolete. These rollers are used for spherical roller bearings and thrust spherical roller bearings. 6. Spiral Roller It is a hollow roller rolled from a steel strip with a special section. It is divided into left-handed and right-handed. This type of roller is not widely used and is mainly used for spiral roller bearings subjected to impact loads. 7. Pillar hole roller The center of the pillar hole roller has a through hole for mounting the post for fixing on the sheet post holder. This type of roller has a cylindrical shape, a conical shape, and a spherical shape, and is mainly used for extra large bearings.
