The NTN KR XH series is a stud-type cam follower built to roll directly against cams, raceways and linear guides instead of sliding along them. It is mounted on a fixed shaft or stud and takes radial loads together with the shock that cam-driven mechanisms normally produce. Sealing and a sturdy build suit dusty areas, chip exposure and permanent lubrication.

Reading the code helps you order the right item. KR stands for a cam follower with a stud or pin. The digits after it give the outside diameter in millimeters. The X marks a cylindrical outer profile, and the H points to the version with a steel cage and reinforced sealing. Every part number in the series follows this same pattern, so only the size changes from one reference to the next.

Typical applications include machine tool cams, transfer systems, presses, packaging equipment and automated assembly lines. They also show up in lifting guides, transport rails and indexing mechanisms, where rolling contact on a hardened raceway takes the place of a sliding bushing. Because the roller absorbs radial and impact loads, it is common in metalworking, food processing and automotive plants.

When choosing a roller, start with the outside diameter your housing accepts, then look at the sealing needed for the environment (dust, water, temperature) and the internal clearance that fits the running speed. The support surface should be hardened, ground and well aligned with the cam or guide. Use the lubricant specified for the part and renew it according to the duty cycle. Poor alignment speeds up wear on both the profile and the seal.

These cam followers can be exchanged with equivalents from other makers that use the same dimensional system, such as the KR series from INA or SKF, provided the outside diameter, width and stud type line up. If you only have another brand's number, or a part you cannot identify, send the main dimensions and we will point you to a compatible equivalent so the replacement drops in without reworking the housing.

For a quote on an NTN KR XH series cam follower, message us on WhatsApp or email the full part number, for example KR35XH or KR72XH, or the dimensions of the part being replaced. Our team replies promptly and can suggest a compatible alternative when one applies.
