LMK...UU Square-Flange Linear Bushings — Sizes & Specifications
The LMK...UU series is the square-flange version of the LM bushing: the four-bolt square flange mounts directly to the machine frame, which suits housings and panels laid out for a square fixing face. It is widely used in automation equipment, CNC machinery and 3D printing equipment. BPK supplies the full standard range from LMK6UU to LMK60UU, factory-direct from Yandian, Shandong, for importers, distributors and OEM buyers.
