Deep Groove Ball Bearings Generation C
FAG deep groove ball bearings –standardized, but available in a wide variety
Deep groove ball bearings allow very high speeds and low friction. For this reason, they are indispensible in electric power tools.
Along with the basic design listed in the catalog, FAG offers numerous variants: bearings with one or two sealing shields, with special radial internal clearance, with increased accuracy and protection against corrosion or the passage of electrical current, etc. And if this selection does not suffice, we will jointly find a solution that is matched to your requirements.
Generation C – with improved seals
FAG Generation C deep groove ball bearings have been very successful in the electric motor market. With 50 % less noise and around 35 % less friction, these bearings increase the efficiency of motors and meet the increasingly strict requirements for minimizing noise. The customer can choose between a robust riveted steel cage and a polyamide cage that is suitable for high speeds depending on the requirements of his application.
A new seal concept significantly improves bearing operating life. Sealed Generation C deep groove ball bearings offer the perfect balance between friction and sealing action. They are greased for life with high-quality grease.
The star of the show is the new HRS lip seal made of nitrile butadiene rubber. At high speeds in particular, this seal has lower friction and generates less heat than the previous RSR seal. The effectiveness of the sealing action has also been increased.
