Roller bearings are short cylindrical, tapered or drum-shaped rollers for rolling body rolling bearings. There are mainly short cylindrical roller, double row spherical roller, tapered roller and thrust roller and other structure type.
Qingdao Fuqin international can supply many types of rollers, such as cylindrical roller, needle roller, and so on.
These rollers are mainly used in cylindrical roller bearings, but also roller assemblies can be used directly in machinery. This type of roller has been standardized in size and is available as a commodity roller for design and user selection.
This type of roller is divided into two types: with shaft and without shaft. It is mainly used for long cylindrical roller bearings, and the roller assembly can also be directly used in machinery.
This type of roller is mainly used in needle roller bearings, universal joint needle roller bearings and thrust needle roller bearings, and needle roller assemblies can also be directly used in machinery. This type of roller has been serialized in size for design selection. According to the needs of the bearing structure, the shapes of the ends of the needle rollers are cone-shaped, flat-headed, round-headed, etc.
It is a circular truncated cone, and its cone angle is usually 1° to 4°20', and some are less than 1° or greater than 4°20', mostly 2°. The length of the roller generally does not exceed twice the diameter of the large end of the roller. This type of roller is mostly used in tapered roller bearings, and rollers with large cone angles are basically used in thrust tapered roller bearings.
The rolling surface of the roller is spherical. Bearings using this type of rollers have self-aligning performance and can withstand large loads. Spherical rollers are divided into asymmetric type and symmetrical shape. Generally, the large end surface of the asymmetric shape is a spherical surface, and the two ends of the symmetrical shape are flat end surfaces. Symmetrical spherical rollers have better performance, while asymmetrical ones are eliminated. These rollers are used in spherical roller bearings and thrust spherical roller bearings.
