SKF deep groove ball bearing

SKF deep groove ball bearing is an instrument device with open, double-sided sealing ring. The sealed bearing has a groove on the outer ring that can be installed with a sealing ring or a dust cover. It is suitable for high speed and even extremely high speed. operation.

The basic types of SKF deep groove ball bearings are open type, double-sided with sealing ring or double-sided with dust cover. In the need of production, the sealed bearing has a groove on the outer ring that can be installed with a sealing ring or a dust cover. grooves, also available as open bearings.

tolerance
Basic types of SKF single row deep groove ball bearings are available with normal tolerances. Bearings with tighter manufacturing tolerances can also be provided as long as the user requires.

Bearing clearance
Basic types of SKF single row deep groove ball bearings use a basic clearance set. Bearings with larger clearances are available on request.

cage
Basic types of SKF deep groove ball bearings without the cage suffix in the designation are fitted with stamped steel cages. Deep groove ball bearings with the suffix M in the designation have a solid brass cage guided by steel balls.

center
Due to the limited self-aligning ability of SKF deep groove ball bearings, the concentricity of the bearing installation seat is required to be good. Poor concentricity will affect the smoothness of operation, increase the stress of the bearing, and thus 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 bearings can only allow a small deflection angle, which also depends on the size of the load.

allowable speed
For SKF bearings, the reference speed may exceed the limit speed in some cases. Specific operating conditions are taken into account by determining the amount of heat generated at the allowable operating speed.

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