KOYO Bearing

KOYO NEEDLE ROLLER BEARING K4X7X7TN

Radial needle roller and cage assemblies have a steel cage that

provides both inward and outward retention for the needle rollers.

The designs provide maximum cage strength consistent with the

inherent high load-ratings of needle roller bearings. Accurate

guidance of the needle rollers by the cage bars allows for operation

at high speeds. Needle roller and cage assemblies have either one

or two rows of needle rollers.
