Choosing the right bearing

Match the shaft diameter and verify the housing bore and available installation length before ordering. This long model is intended for a longer bearing body where the installation calls for extended axial support. LM-UU and LM-LUU models of the same bore have different body lengths and should not be assumed interchangeable in a fixed housing.

The dimensions above are nominal LM-series reference dimensions. Verify required tolerances and fit for your assembly. Use with a suitable supported round shaft; the bearing does not provide a complete guide system on its own.
