The NTN KRV series cam follower is a cylindrical roller bearing with an integrated mounting stud, designed to withstand radial loads and transmit motion directly on cams, tracks or guides. It is used in lifting mechanisms, conveyors, machine tools and automation equipment, where the outer wheel rotates in contact with a cam surface. Its robust construction absorbs impacts and combined loads, and it is mounted via the threaded stud or screw fixing, depending on the model.

The KRV series designation is interpreted as follows: the letters KR identify a cam follower with needle cage and stud; the V indicates that the outer track is cylindrical, without a flange. The number that follows —for example, in KRV30XLL/3AS or KRV40XLL/3AS— indicates the outer diameter in millimeters. The suffixes XLL and /3AS refer to sealing and lubrication: XLL indicates a double sealing lip, and /3AS a design with high-temperature grease and specific clearance. These codes allow you to order the exact variant your equipment needs.

In Argentine industry, NTN KRV series cam followers are used in packaging machine cams, machining center linear guides, chain conveyors, presses and continuous motion equipment. They also appear in the food, automotive and metallurgical industries, where a compact bearing is required to withstand high radial loads and demanding working conditions. MR Accesorios Industriales sells this series for replacement and new projects, with technical advice to choose the correct configuration.

To select a KRV cam follower, take into account the outer diameter, width and the type of fixing your mechanism accepts. The XLL seal protects against contaminants and retains lubrication; if the environment has dust or chips, it is advisable to prioritize that variant. Alignment between the roller and the track is critical: a misaligned mounting accelerates wear. Also check lubrication: the /3AS series already incorporates long-life grease, but in high-speed or high-temperature applications it may require periodic relubrication.

NTN KRV series cam followers are interchangeable with those of other brands that follow the same dimensional nomenclature, such as the KRV series from INA or SKF, as long as outer diameter, width and stud type match. If you have another brand's part number, we can identify the equivalence and quote you the corresponding NTN option. Interchangeability is not always direct: verify tolerances and sealing before replacing. At MR we advise you so the substitution is safe.
