Cylindrical bore type for 3.15 in. / 80 mm. shaft diametr, outer ring surface is cylindrical.
The bearing rings are made of through-hardened carbon bearing steel. Ceramic rolling elements, made from silicon nitride.
Principal dimensions is 3.150х4.921х0.866 in. equal to 80х125х22 mm.
Without seals.
Machined brass cage.
Metric series product.
Most widely used bearing type, optimized for low noise and low vibration, provide low friction and high rotational speeds. Open bearings that are also available capped may have recesses in the ring side faces.

Hybrid ceramic bearings contribute higher performance, longer service life and reduced maintenance requirements, they can lead to reduced energy use and fewer resources.
This bearing suitable for high speeds, offer electrical insulation and superior durability in challenging or extreme application conditions.
