The NSK CRS series cam follower is a roller bearing with its own stud, designed to be mounted directly on a cam, a guide or a raceway and to withstand radial loads with reciprocating motion. It is used where a compact, high-capacity contact wheel is needed, such as machine tools, packaging equipment, conveyors and cam mechanisms in general.

The CRS series designation is read with the number that follows the hyphen: the numbers indicate the roller size, and the -1 suffix distinguishes the variant with a sealing or stud configuration. Thus, CRS-8 and CRS-8-1 share the same size but are not the same execution, and the same applies to CRS-10 and CRS-10-1.

In Argentine industry they appear in cams of packaging machines, conveyor linear guides, indexing mechanisms, presses and automation equipment. They are also found in the food and beverage industry, where washdown demands executions with good sealing, and in textile and woodworking machines that work with reciprocating motion and moderate to high radial loads.

To choose correctly, you must look at the outer diameter and the width of the contact raceway, the stud type and the mounting method, and above all the sealing: in environments with dust, chips or water, the variant with a seal is preferable. Mounting requires alignment with the cam or guide, correct stud tightening and adequate lubrication; poor alignment shortens the roller's life even if the load is as expected.

Cross-references between brands are handled by dimensions and roller type: an NSK CRS can be cross-referenced with references from other companies that share the outer diameter, width and stud shape, but the code does not always match. If you bring the code from another brand or an unidentified part, at MR we cross-reference it and tell you the compatible alternative.
