Ball bearing units consists of pre-lubricated sealed ball bearings and a housing which varies in shape.

Ball bearing units consists of pre-lubricated sealed ball bearings and a housing which varies in shape.

They are capable of aligning themselves efficiently using the spherical fitting surface between the bearing and housing, effectively preventing overloads due to misalignment.

Our Koyo branded Ball Bearing Units are highly accurate and feature excellent load resistance. They are completely sealed, and provided with a re-lubrication feature. Ball bearing units without a re-lubrication feature are also available.

FAQ

What is a cylindrical roller bearing?

Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but are not true cylinders. Instead, these rollers are crowned or end-relieved to reduce stress concentrations. This geometry results in low friction and allows for high-speed applications.
