bearing supplier are pivotal parts in mechanical equipment. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load during the transmission of the equipment. Bearings are classified into radial bearings and thrust bearings according to different bearing directions or nominal contact angles.

  1. Angular contact ball bearings

There is a contact angle between the ring and the ball. The standard contact angles are 15°, 30° and 40°. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the more conducive to high-speed rotation. Single row bearings can Withstand radial load and unidirectional axial load. The two single row angular contact ball bearings combined on the back of the structure share the inner ring and outer ring, which can bear radial load and bidirectional axial load.

  1. Self-aligning ball bearings

Double-row steel balls, the outer ring raceway is inner spherical, so it can automatically adjust the axis misalignment caused by the deflection or misalignment of the shaft or housing. The tapered bore bearing can be easily installed on the shaft through the use of fasteners. Withstand radial load.

  1. Spherical roller bearings

This type of bearing is equipped with spherical rollers between the outer ring of the spherical raceway and the inner ring of the double raceway. According to the internal structure, it is divided into four types: R, RH, RHA and SR. Because the arc center of the outer ring raceway is The center of the bearing is consistent, and it has self-aligning performance, so it can automatically adjust the shaft center misalignment caused by the deflection or misalignment of the shaft or housing, and can withstand radial load and bidirectional axial load.

  1. Thrust spherical roller bearings

In this type of bearing, the spherical rollers are arranged obliquely. Because the raceway surface of the raceway is spherical and has self-aligning performance, it can allow the shaft to have a certain inclination, and the axial load capacity is very large. It can also bear several For radial load, oil lubrication is generally used during use.

  1. Tapered roller bearings

This type of bearing is equipped with truncated cone-shaped rollers, the rollers are guided by the large rib of the inner ring, and the design makes the vertices of the inner ring raceway surface, the outer ring raceway surface and the conical surface of the roller rolling surface intersect with the center line of the bearing On the point. Single row bearings can bear radial load and unidirectional axial load, double row bearings can bear radial load and bidirectional axial load, suitable for U-Joint With 4 Grooved Round Bearings heavy load and impact load.
