Bearing advantages and features
Features and benefits of high temperature deep groove ball bearings include:
No need for relubrication
All variants are lubricated for life with a graphite-based high temperature lubricant, except for type VA201 open bearings with stamped steel cages (without dust shields). VA201 open bearings require relubrication.
easy to replace
The outer dimensions are the same as those of standard bearings.
Operating temperature up to 350 °C (660 °F)
Its internal radial clearance and the lubricant used are optimized for high temperature operation.
Protect bearings from solid contamination
A dust cover (designation suffix 2Z) protects the bearing from contamination.
Enhanced running-in performance
The entire bearing surface is manganese phosphide treated.
Design and Variation
The SKF deep groove ball bearing range for high temperature applications offers solutions for different combinations of operating temperatures and speeds.
High temperature deep groove ball bearings can be protected from contamination by built-in dust caps, external dust caps, or a combination of the two.
For high temperature bearings that require a simplified design seal, metal dust caps are recommended as the first choice. Dust cover:
Prevents solid contamination from entering the bearing
Non-contact, no friction or wear
Its materials and design are especially suitable for high temperature service
