XM-RKYR52/0.636160.K is a heavy‑duty V‑groove guide roller bearing of eccentric type. It has a 52mm outer diameter and 1 mm shaft eccentricity, and is built to perform reliably in high‑load linear motion systems.

Engineered for heavy‑duty performance, this unit combines a thick‑walled outer ring with double‑row tapered rollers to achieve superior radial and axial load capacity, strong shock resistance, and long service life in harsh environments. Pre‑lubricated and fitted with dual rubber seals (2RS), it performs reliably in dusty, oily, or high‑vibration working conditions.

It is extensively applied in automated logistics (stackers, AGVs), packaging machinery, CNC machine tools, truss robots, and woodworking/glass processing lines, guaranteeing precise guiding and stable rolling for heavy‑load linear conveying and positioning systems.

RKYR52 differs from RKY52 in that it is equipped with a built‑in eccentric shaft,all other dimensional specifications are the same.
