Cylindrical bore type for 1.969 in. / 50 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 1.969х4.331х1.063 in. equal to 50х110х27 mm.
Capped by non-contact steel shields on both sides, filled with the appropriate amount of high quality grease under clean conditions. Typically should not be washed or relubricated, lubricated for the life of the bearing.
Polymer cage.
Metric series product.
Most widely used bearing type, optimized for low noise and low vibration, provide low friction and high rotational speeds. Capped bearings require less maintenance than open type bearings.

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.
