Ball bearing unit information

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 and JIB 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.

Longer lubrication life The solid grease lubricating the bearing has been heathardened and is a mixture of lubricant and ultra high moleculer weight polyethylene. The solid grease reduces leakage, prolonging lubricant life especially when used under conditions of vibration or centrifugal force. Also, this grease will not homogenize when water penetrates into the bearing raceway.
