Roller bearing is widely used in modern mechanical industry. Roller bearing is also a kind of rolling bearing. Its work is mainly to support the components by means of rolling contact between the components. Most of them have been standardized, and roller bearings have the advantages of easy selection, high rotating accuracy.

Roller bearings are divided into: cylindrical roller bearings, tapered roller bearings, self-aligning roller bearings.

Among them, cylindrical roller bearings have been standardized in size, load-bearing capacity, suitable for high-speed rotation. Can be used as a commodity roller as selection, design. Cylindrical roller bearings are mainly used in railway, wind turbine, mining machinery, metallurgical equipment, injection molding machine, paper-making machinery, engineering machinery, gear devices, motors, machine tools, pumps and compressors, motorcycles and so on. The structure of cylindrical roller bearing is separable between the inner and outer rings. Plain cylindrical roller bearings can be moved relative to each other on shafts; one with a single rib and the other with a double rib can withstand a certain degree of unidirectional axial load. Tapered roller bearings are separate, the inner and outer rings can be installed separately, generally using steel plate stamping cage. Spiral roller bearings are used in self-aligning roller bearings and thrust self-aligning roller bearings. When the shaft and the bearing seat are bent, it can be adjusted automatically to prevent the bearing from overloading. The curvature center of outer ring raceway surface is consistent with the bearing center, so it has the same self-aligning function as self-aligning ball bearing. Self-aligning roller bearings, suitable for heavy load, impact load, radial load capacity. Can be directly installed in the tapered shaft, the bore is tapered bearing. The utility model uses a disassembly sleeve and a set sleeve to be installed on a cylindrical shaft. The use of brass car-made cage, steel plate stamping cage.
