Cam followers in the NTN KRT series are cylindrical roller bearings with a crowned outer surface. They handle high radial loads and are used in cam drives, guide tracks and similar follower arrangements. The inner bore mounts directly on a shaft, while the outer ring rolls against the cam or track. For maintenance and purchasing teams, the series offers a compact, rigid option for mechanisms that need load capacity in a small envelope.

Reading the part number is straightforward. The letters KRT identify the cam follower family, and the number that follows gives the outside diameter in millimeters. So KRT16 measures 16 mm across the outer diameter, KRT22 measures 22 mm, and other sizes follow the same pattern. When suffixes appear, they point to variations in sealing, cage design or tolerance. Send the complete part number and we can confirm what those suffixes mean for your application.

Typical uses include machine tools, packaging lines, conveyors, presses, drive cams, linear guides and lifting mechanisms. Plants in food processing, automotive, metallurgy and plastics rely on this type of roller because it takes combined loads and stands up to tough operating conditions. The small profile and high rigidity suit tight mounting spaces where precision and durability matter.

Selection starts with the radial and axial loads the follower will see, along with speed, lubrication method and the surrounding environment. Mount it on a shaft with the correct fit and check alignment so eccentric loads do not develop. Some versions use sealed, permanent lubrication; others need periodic relubrication. When the follower runs against a cam, the cam surface should be ground and hard enough to support a long service life for the assembly.

For interchangeability, NTN KRT series cam followers can often replace similar products from other makers, but always verify the critical dimensions: outside diameter, bore diameter, overall width and seal type. Nomenclature differs between manufacturers, so the safest approach is to quote by exact part number or by measured dimensions. If you send the original part data, we can identify a compatible alternative.
