SKF deep groove ball bearing

SKF deep groove ball bearing is an instrument device with open and double-sided sealing ring. The bearing with seal is provided with a groove with sealing ring or dust cover on the outer ring, which is suitable for operation at high speed or even extremely high speed.

The basic types of SKF deep groove ball bearings are open type, double-sided with sealing ring or double-sided with dust cover. For the needs of production, the bearing with seal is provided with a groove on the outer ring that can be installed with sealing ring or dust cover, which can also be supplied as open bearing.

tolerance

The basic type of SKF single row deep groove ball bearing adopts ordinary tolerance. As long as users need, we can also provide bearings with stricter manufacturing tolerances.

bearing clearance

The basic type of SKF single row deep groove ball bearing adopts the basic clearance group. Bearings with greater clearance can be provided as required.

Cage

The basic type of SKF deep groove ball bearing without cage suffix in the model is equipped with steel plate stamping cage. Deep groove ball bearings with suffix m in the model have brass solid cage guided by steel ball.

Centering

Due to the limited automatic centering capacity of SKF deep groove ball bearing, it is necessary to install the bearing with good concentricity. Poor concentricity will affect the stability of operation and increase the stress of the bearing, so as to shorten the service life of the bearing. In order to keep the additional stress on the bearing within the allowable range, SKF deep groove ball bearing can only allow a small deflection angle, which also depends on the load.

Allowable speed

In some cases, the reference speed of SKF Bearing may exceed the limit speed. Specific working conditions are considered by measuring the heat generated at the allowable working speed.

heat treatment

SKF deep groove ball bearing can work at a temperature higher than 150 ℃ after heat treatment. Bearings with an outer ring diameter greater than 240mm can work at a temperature not higher than 200 ℃ (pay attention to the use restrictions of sealed bearings).
