Product Description

Needle Roller Bearings

Needle roller bearing is a special type of roller bearing that has cylindrical rollers that resemble needles because of their small diameter.

Normally, the length of rollers in roller bearings is only slightly more than its diameter. When it comes to needle bearing, the length of rollers exceeds their diameter by at least four times.

As needle bearings have a smaller diameter, more rollers can be fit in the same space which increases the surface area in contact with the races. Thus, they are capable of handling high loads. The small size can also prove helpful in applications where space is limited as they require smaller clearances between the axle and the housing.
