A cam follower from the NTN KRV series is a cylindrical roller bearing built around a threaded stud, so it bolts straight onto a machine frame and is locked in place with a nut. Its outer ring carries a crowned profile, which lets it handle radial loads and tilting moments in cam drives and guide tracks. You will find these rollers in reciprocating, conveying and positioning equipment where repeatable motion matters.
Reading a KRV code is straightforward once you know the pattern. KRV tells you it is a cylindrical roller cam follower with a steel cage and a crowned running surface. The figure after the letters is the outside diameter in millimeters, so KRV10H/3AS measures 10 mm across the outer ring. An H in the suffix means the stud head has a lubrication groove, and /3AS points to a modified seal and cage inside. Codes in this series therefore differ mainly by outside diameter.
Typical installation sites include actuating cams, linear guide tracks, roller conveyors, packaging lines, presses and automated positioning units. Because the stud-mounted design resists combined loads and tolerates dirty surroundings, these rollers suit plants where equipment runs continuously and smooth travel is expected. Automotive, food, textile and metalworking operations all use them.
When specifying a replacement, work from the outside diameter, the width and the seal style. Variants exist with lip seals and with the head lubrication groove. The stud must sit in a bore machined to the correct tolerance and be tightened with a lock nut. Aligning the roller properly keeps axial loads down, and regreasing through the H groove on a regular schedule helps the bearing hold steady performance.
Cam followers sold under other brand names can look similar on paper, but dimensions and load ratings should be checked before any swap. The NTN KRV line is known for consistent quality, and MR Industrial Accessories LLC carries it within its bearing range. If you are replacing a worn roller, the exact code or a set of measured dimensions is the safest starting point.

Frequently asked questions
- What does the H suffix mean on a KRV roller?
- It means the stud head is fitted with a lubrication groove, so the roller can be regreased in place without being removed from the machine.
- How do I pick the correct cam follower?
- Start with the outside diameter, width, seal type and the loads the application applies. Send the original code or your measurements on WhatsApp and we will quote the matching reference.
- Can NTN KRV rollers replace cam followers from other brands?
- Possible equivalents exist, but confirm dimensions and load capacities first. Share the other brand's code with us and we will point you to a compatible option or quote the exact code.
