Description
NSK CR-30 belongs to cam follower, part of our Bearings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for CR-30 and any equivalents.
A cam follower from the NSK CR series combines a cylindrical roller bearing with a stud that mounts straight onto a cam track or a linear guide. It works where motion is radial and the rotation runs continuously or back and forth, acting as a support or cam roller inside the mechanism. The construction suits tough jobs in industrial machinery.
Reading the code is straightforward: CR comes first, then a number tied to the roller size. CR-8, CR-10, CR-12 and CR-14 each sit at a different outer diameter. Where you see a suffix such as -1, as in CR-8-1 or CR-10-1, the part is a construction variant, often defined by the sealing arrangement or the stud shape. Matching outer diameter, width and mounting style to your application is what pins down the right number.
Typical installations include actuating cams, machine tool guides, conveyors, packaging equipment and linear motion systems. The design carries high radial loads and keeps working where dust, chips or permanent lubrication are part of daily operation.
Selection comes down to radial load, rotation speed and the environment. Sealing matters most: a version with a radial shaft seal keeps contaminants out and helps the roller last. The stud and the raceway need to line up, since misalignment introduces parasitic loads and early wear. Grease or oil lubrication cuts friction and moves heat away.
NSK CR series cam followers can be swapped for equivalent products from other brands when the main dimensions and sealing type line up. Bring us a part number from another maker, or an unidentified part, and we will point you to the compatible alternative. Interchange is never automatic, so check outer diameter, width, stud diameter and fastening type.

Frequently asked questions
- What does the -1 suffix mean on CR-8-1 or CR-10-1 rollers?
- It marks a construction variant within the CR series, usually linked to the sealing type or the stud configuration. Send us the full part number by WhatsApp and we will confirm how a CR-8-1 differs from a CR-8.
- When should I use a cam follower instead of a standard roller bearing?
- A cam follower carries its own integrated stud and mounts directly to the cam or guide, while a roller bearing needs a separate shaft. If your setup calls for a roller with its own stud under radial load, the CR series fits.
- Can NSK CR series rollers replace other brands?
- They can, provided the main dimensions agree: outer diameter, width, stud diameter and sealing type. Give us the original brand part number and we will tell you which equivalent matches.
