A stud-type roller that mounts straight onto a shaft, the NTN KR XLLH cam follower handles radial loads in cams, tracks and linear motion setups. Sealing and lubrication are built in to keep it running in dirty plant environments. MR Industrial Accessories LLC supplies this series to maintenance and purchasing teams across the United States and Latin America.
Reading the code helps you order the right size: KR means cam follower with a needle cage and a cylindrical outside surface, XLLH covers the seal and lubrication package, and /3AS points to heat treatment and dimensional accuracy. In a reference like KR30XLLH/3AS or KR40XLLH/3AS, the digits after KR give the outside diameter in millimeters.
Typical installations include machine tools, packaging lines, conveyors, presses, cam drives and linear guides. Plants in automotive, food processing, metallurgy and plastics rely on these rollers where motion has to stay precise and wear stays low. The sealed construction suits areas with dust, chips or moderate humidity.
When selecting, work from the stud diameter, the radial load and the running speed. Press the roller onto the stud with enough interference so it cannot rotate on its own. Keep the stud and raceway aligned, and rely on the factory grease and seals to hold lubricant in and contaminants out.
NTN KR XLLH cam followers follow the same nomenclature used by other makers, so a comparable part from another brand may fit if dimensions and load capacity line up. Send us the competitor's part number and we will check the match. Our team can also help you confirm the correct size when the original marking is worn.
