The NTN KRV series is a line of cylindrical roller cam followers featuring a crowned outer profile, built to handle high radial loads in cam and guidance roles. The LLH sealing and steel cage make these rollers a practical choice for environments where moderate contamination is present. Machine tools, automation systems and conveyors are common homes for this series. MR Industrial Accessories supplies the KRV series.

Reading a KRV part number is straightforward once you know the pattern. KRV denotes a cylindrical roller cam follower with a steel cage and a crowned outer profile. The digits that follow give the outside diameter in millimeters, so KRV10LLH/3AS is a roller with a 10 mm outside diameter. LLH means labyrinth sealing combined with a rubber lip seal, a setup that keeps contaminants out and lubricant in. The /3AS ending is an NTN internal code that may point to a cage variant or a surface treatment. Other sizes in the series include KRV12LLH/3AS, KRV13LLH/3AS and KRV30LLH/3AS.

These cam followers appear in many industrial settings. In machine tools they work as cam followers within numerical control systems. Automation equipment uses them in linear guides and transfer mechanisms. Continuous conveying setups, such as conveyor belts and drag chains, also rely on them. Automotive, food and metallurgy operations choose them for their capacity to take radial loads and tilting moments. MR Industrial Accessories supplies them with technical guidance to help you select the right roller.

Selecting a KRV cam follower starts with the radial load and tilting moment it must carry, plus the rotational speed and the operating environment. LLH sealing fits environments with moderate dust and humidity; if contamination is heavy or washdowns are frequent, extra sealing may be needed. Mounting calls for precise shaft alignment and proper lubrication, ideally with a high-quality grease. The steel cage provides stable roller guidance, which supports smooth running and a long service life. Follow the recommended tightening torque for the shaft and avoid impacts that could harm the roller edges.

On interchangeability, NTN KRV cam followers can stand in for similar products from other makers when the critical dimensions line up: outside diameter, shaft diameter, overall width and sealing type. SKF, FAG and NSK offer cam followers with comparable designations, though suffixes differ. Check tolerances and load capacity before swapping one roller for another. If you have a part number from another brand or an unidentified part, contact MR Industrial Accessories to get the equivalent NTN reference and a quote.
