The NTN KRV series is a cam follower with a crowned cylindrical outer ring, engineered to handle high radial loads and transmit motion directly on cams, tracks, or guides. Its sealed design and sturdy construction make it a dependable choice for industrial machinery where reliability matters.
Part numbers in the KRV series follow a clear pattern. The base designation KRV identifies a cylindrical roller cam follower with a crowned profile. The numeric portion gives the outer diameter in millimeters: KRV30LL/3AS has a 30 mm OD, KRV32LL/3AS has 32 mm, and so on. The LL suffix means labyrinth seals on both sides, which help retain lubricant and keep contaminants out. The /3AS suffix is an NTN internal code related to cage or surface treatment and does not change the main dimensions.
These cam followers are used in machine tools, automation equipment, conveyors, presses, cranes, and linear guidance systems. They appear in drive cams, support rollers on rails, and lifting mechanisms. Their ability to absorb radial and shock loads suits environments with vibration or intermittent loading, making them common in automotive, metalworking, food processing, and logistics operations.
When selecting a KRV cam follower, confirm the outer diameter, shaft diameter, total width, and sealing type. For dusty or humid settings, the LL seal is recommended. Mounting requires a properly fitted shaft and alignment with the raceway. The unit comes pre-lubricated, but periodic relubrication through the provided hole is advisable in severe duty. Check concentricity and axial clearance to prevent premature wear.
If you are replacing a cam follower from another brand, the NTN KRV series can work if the critical dimensions match: outer diameter, shaft diameter, total width, and sealing. Load capacity and tolerances must also be verified. Send us the original part number or measurements, and our team will identify a compatible NTN reference.
