SJ-LMK Inner Copper Square-Flange Linear Bushings — Sizes & Specifications
The SJ-LMK series is the steel-shell, inner-copper version of the LMK linear bushing family. Importers specify it where the drawing calls for this construction rather than the standard ball bushing. BPK supplies SJ-LMK6 to SJ-LMK60 across the standard shaft range, factory-direct from Yandian, Shandong, for importers, distributors and OEM buyers.

Model notation identifies a family, not a fixed size. Please confirm bore diameter, outer diameter, overall length, mounting, sealing, material, and load requirements with your drawing.
Every model above links straight to the inquiry form with the model prefilled — send your quantity and destination, and we prepare the quotation.
Options & matching parts
The same steel-shell, inner-copper construction is available across the SJ family — plain, flanged and housed versions are listed on the products page. Standard ball-type LM...UU bushings remain the default where the drawing does not specify this construction.
