These are common LMK20UU nominal reference dimensions; dimensions and mounting details can vary by manufacturer or batch. Verify critical fit against the actual bearing before machining.

Selection and installation

Choose the nominal shaft bore first, then verify the bearing body diameter, overall length, flange footprint and four-hole mounting pattern before installing or replacing the bearing. Bearings that use the same shaft diameter may have different flange shapes or mounting positions. The LMK-UU and LMK-LUU versions use different overall lengths; select the one specified by the assembly design.

Use a clean, straight shaft suitable for ball-type linear bearings. Align the shaft and bearing before tightening the mounting hardware, and check free movement by hand.
