Classification of rollers

Cylindrical roller bearing

This kind of planetary gear shaft is suitable for cylindrical roller bearing, and roller bearing parts can be used in mechanical equipment immediately. This kind of roller bearing has been standardized in specification, and can be used as the product roller bearing for design scheme and customer selection.

Long cylindrical roller bearing

This kind of roller bearing is used for shaft diameter and no shaft diameter respectively. It is suitable for long cylindrical roller bearing. Roller bearing parts can be used in mechanical equipment immediately.

Kingpin

This kind of roller bearing is suitable for cylindrical roller bearing, cross shaft cylindrical roller bearing and thrust needle bearing. It can be used in mechanical equipment immediately. This kind of planetary axle tolerance has been generalized in specifications for selection of design scheme. According to the requirements of rolling bearing construction, the top of the two sides of the needle has the shape of cone head, round head, round mouth, etc.

Tapered roller bearing

It is a circular truncated cone with a cone angle of 1 ° - 4 ° 20 ', which is also less than 1 ° or more than 4 ° 20', mostly 2 °. Generally, the length of roller bearing does not exceed twice the diameter of the big end of roller bearing. This kind of roller bearing is mostly used for deep groove ball bearing, and the roller bearing with large cone angle is mostly used for attracting investment.

Curved roller bearing

The turning surface of roller bearing is like the earth curved surface. The rolling bearing with this kind of professional planetary axle has the characteristics of full-automatic centering, which can bear a very large load. Curved roller bearings are divided into two types: asymmetric and symmetric. Generally, the large inner hole of asymmetric and dense is curved surface, and the two sides of symmetric shape are flat inner hole. The symmetrical curved roller bearing has good characteristics, while the asymmetrical densified roller bearing is a substitute. This kind of roller bearing is used for self-aligning bearing and investment inviting self-aligning bearing.

Spiral roller bearing

This is a hollow roller bearing made of steel chain with unique cross section, which can be divided into left-handed and right-handed. This kind of roller bearing is not widely used and is suitable for spiral roller bearing under impact load.

Support hole roller bearing

The support hole roller bearing management center is provided with a buried hole, which is used for mounting support, so as to be fixed on the block support maintenance wall. This kind of roller bearing is cylindrical, tapered and curved, which is suitable for giant rolling
