High-temperature bearings
Deep groove ball bearings operate reliably in extreme conditions and eliminate the need for expensive special bearings or lubricants.
FEATURES & BENEFITS
- 10- to 100-mm bore diameter; available with cylindrical bores for mounting
- Shaft speeds to 100 rev/min
- Graphite cage technology for long life and little maintenance
- Operating temperatures of -238° to 662° F
- Double-shielded designs protect against solid contaminants and retain lubricant
