1. Cylindrical roller this kind of roller is mainly used for cylindrical roller bearing, also can be directly used for mechanical components will roller. The roller in size has standardized, and can be used for goods for design and users to choose the roller.
2. Long cylindrical roller such roller points with and without trunnion trunnion with two, mainly for long cylindrical roller bearing, also can be directly used for mechanical components will roller.
3. Needle this kind of roller is mainly used for needle bearing, universal joint needle bearings and thrust needle bearing, can also needle component directly for machinery. The roller in size has series, for design choice. According to the needs of the bearing structure, the needle at both ends of the head shape has cone shape, form, the crew cut head round head shape, etc.
4. Tapered roller is round cut cones, the cone Angle usually 1 ° ~ 4 ° 20 ', also have less than 1 ° or more than 4 ° 20 ', for more than 2 °. Roller length in general not more than two times the diameter of the main roller. This kind of roller more for taper roller bearings, large taper Angle of roller basically used to thrust taper roller bearings.
5. Spherical roller rolling MianCheng spherical roller shape. By this kind of the roller bearing has to be automatic self-aligning performance, can handle a lot of load. Spherical roller points the unsymmetrical and symmetric form, general of asymmetric big end for the sphere, symmetric form two end for flat end. Symmetric form spherical roller performance is good, and the unsymmetrical for eliminated forms. This kind of roller for spherical roller bearing and thrust self-aligning roller bearings.
6. Screw roller it is to use the special section steel strip rolling a hollow roller, points levorotatory and dextral two kinds. This roller application is not very widely, mainly for the impact load screw roller bearings.
7. Pillar hole roller pillar hole with roller center hole, the hole is used to hold pillar, so that a fixed in the flake pillar keep on the shelf. The roller shape, the cone, cylindrical spherical shape, mainly used for large bearings.
