NTN cam followers and support rollers

Catalog examples include NUTR202/3AS, NUTR202X/3AS, NUKR 30/3AS and NUKR 30X/3AS. Retain spaces, slashes and letters. Similar codes help locate the family but do not establish identical outer geometry or mounting arrangements.

Record whether the roller fits on a separate shaft or incorporates its fastening element. Side and front photographs document that distinction without relying on an abbreviated reference or a similar catalog image.

The mating track is part of the assembly review. Explain whether the roller follows a cam profile, guides travel or supports a moving load. State whether it works alone or with other rollers sharing the function.

For marks on the outer surface, record their location and the condition of the opposing track. These observations support further investigation but do not prove a failure cause. Keep the requested designation separate from mechanism observations rather than automatically selecting a different variant in response to unexplained wear.

Send MR the NTN code, quantity and photographs of the installed roller or exploded assembly. Add confirmed mounting dimensions and identify components that remain in the machine. For several rollers, label each position: similar-looking parts in one machine may perform different tasks.
