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; it can also be used directly in machinery.
3. Rollers of this type are mainly used for needle bearings, universal joint needle bearings and thrust needle bearings; they can also be used directly in machinery. These rollers are serialized in scale; Selection. According to the requirements of the bearing layout; the head of the needle has a shape of a cone, a flat head, a round head, and the like.
4. The tapered roller is a circular truncated cone; its taper angle is usually 1°～4°20′; it is also less than 1° or greater than 4°20′; most is 2°. The roller length usually does not exceed the diameter of the big end of the roller. Twice. This type of roller is mostly used for tapered roller bearings; large cone angle rollers are basically used for thrust tapered roller bearings.
5. The rolling surface of the spherical roller roller has a spherical shape. The bearing selected for this roller has an active centering function; it can accept a large load. The spherical roller is divided into an asymmetric type and a symmetrical shape; usually the large end face of the asymmetry is Spherical surface; the symmetrical shape of the two faces is a flat end face. The symmetrical spherical roller function is better; the non-symmetric type is the screening mode. This type of roller is used for spherical roller bearings and thrust spherical roller bearings.
6. Spiral roller It is a hollow roller made of steel strip with special section; it is divided into left-handed and right-handed. This kind of roller is not widely used; it is mainly used for spiral roller bearing subjected to impact load.
7. The pillar hole roller pillar hole roller has a middle through hole; the hole is used for supporting the pillar; so as to be fixed on the sheet pillar holding frame. The roller has a cylindrical shape, a conical shape, and a spherical shape; Bearing.
