The NTN KR series cam follower is a stud-type roller bearing. Its integrated stud mounts to the machine frame while the outer ring rolls along a cam, guide or raceway. This makes it a compact option for lifting, conveying and automation mechanisms that call for accurate guidance and the ability to carry radial loads.

Reading the code: the letters KR come first, then a number that gives the outside diameter in millimeters. The X suffix marks a defined roller variant. Examples include KR30X, KR32X and KR35X, with outside diameters of 30, 32 and 35 mm. The X suffix points to a particular sealing arrangement or profile shape under the manufacturer's coding system. When selecting, check the outside diameter, the width and how the stud will be mounted.

Typical duties include conveying and lifting equipment, machine tools, packaging lines, robotics and automation, presses, and cam drives in general. Food processing, automotive, metalworking and logistics operations use these rollers because they handle combined loads and resist wear. MR Industrial Accessories supplies the NTN KR series for these requirements.

Selection depends on the radial and axial loads, the rotation speed, the operating environment and the lubrication method. The stud must be aligned correctly with the raceway; misalignment creates eccentric loads that shorten service life. For dusty or humid conditions, choose a version with lip seals. Some designs are lubricated for life, while others need periodic greasing. Follow the manufacturer's torque and securing instructions for the stud.

Cam followers from different makers can be interchanged when the main dimensions (outside diameter, width, stud diameter) and load ratings match. SKF, INA, NSK and Timken are among the brands offering comparable parts, but always confirm the full designation and tolerances. If you are replacing a roller from another brand, send the part number and dimensions; we will point you to the compatible NTN option or another brand that suits the job.
