Needle Roller Bearings

The design provides maximum cage strength consistent with the long life requirements Bearings are also available with reinforced plastic cages for use where operating conditions permit Before applying bearings with plastic cages please contact AST sales or engineering personnel Sealed Bearings Caged drawn cup caged needle roller bearings

Needle roller bearing

A needle roller bearing is a special type of roller bearing which uses long thin cylindrical rollers resembling needles Ordinary roller bearings' rollers are only slightly longer than their diameter but needle bearings typically have rollers that are at least four times longer than their diameter Like all bearings they are used to reduce the friction of a rotating surface
