When a mechanism needs a roller that also serves as a mounting point, the NTN KR series cam follower fits the role: a stud-type roller bearing with a threaded end that bolts through a plate or support and locks with a nut. This design suits reciprocating motion, linear guidance and transfer equipment where a simple, serviceable roller is preferred.

Reading the code is the first step in selection. The digits after KR give the roller outside diameter in millimeters, so KR30 and KR40 point to different roller sizes. Letters or numbers after that core identify sealing arrangement, head profile and stud end. Because those suffixes decide how the unit mounts and how well it keeps out contaminants, always confirm the full code before ordering.

Typical applications include cam actuation, chain and belt guidance, transfer lines, packaging machinery, sheet feeders, handling systems and general automation. The threaded stud lets maintenance teams replace the roller without reworking the support, which matters when the roller runs against a cam or guide that wears over time.

Selection should account for the outside diameter your mechanism requires, the sealing type for the environment (dust, chips, washdown) and the lubrication plan. The roller is held by a nut on the stud thread, and alignment with the raceway should be checked to prevent side loads. For cam applications, verify the cam profile and mounting clearance. The KR series comes in several head and sealing configurations, so send the complete code and we will identify the matching variant.

Cam followers interchange by dimensional designation: a KR with the same outside diameter number and stud type is generally equivalent across manufacturers, even when sealing or head suffixes differ. For an unidentified part, provide the main dimensions — outside diameter, stud diameter, thread and width — and we will quote the equivalent NTN reference. We can also review interchangeability with other brands we supply.

If you already have the code, send it via WhatsApp or email and our team will quote it promptly. If you need a sealing or head variant that is not listed, write to us with the exact model and we will suggest the compatible alternative.
