NUKR90 NUKRE90 Cam followers (stud-type track rollers) Bearings

The NUKR90 and NUKRE90 series studded cam followers (track rollers) are designed for smooth rolling on a variety of tracks.

They feature a double-row full-complement cylindrical roller construction, using solid threaded studs instead of inner rings, and are equipped with a thick-walled outer ring with a curved running surface.

The NUKRE90 includes an eccentric ring for easy clearance adjustment, while the NUKR90 does not.

These bearings are pre-sealed for direct mounting and support lubrication via the studs, extending their service life. They are widely used in cam drives, conveyor systems, automated machinery, and other heavy-duty applications.

NUKR90 and NUKRE90 are used in the GBR90/GER90 series guide rail roller boxes.

The GBR90/GER90 series guideway roller housings (cam follower housings) are designed for heavy-duty linear motion in gantry robots and automated machinery.

They integrate multiple studded cam followers (Ø90mm) into a precision-machined housing, providing high rigidity, smooth rolling, and precise positioning on rectangular guideways. They are ideal for long-stroke, high-load applications such as gantry handling and industrial automation.
