LM Square Flange Linear Series

Home > MAOZE Products > Standard Flanged Linear Bearings > Standard Flanged Linear Bearing

The LM Square Flange Linear Series integrates a flange at one end of the sleeve for direct bolt mounting, eliminating separate housings with high running accuracy and compact structure. Round (LMF), square (LMK) and cut-edge (LMH) flange types are available in standard, long, medium (UD), compact (TH) and embedded (E) versions.

Features

Integrated flange for direct bolt mounting
Round, square or cut-edge flange types
Standard, long, compact (TH), medium (UD) options
Embedded type (-E) for blind-hole press fit

Model Designation

LMK = square flange; LMEK European, LMBK inch; -L long, -UD medium, -RB reverse counterbore.

Specifications

See the parameter table for detailed specifications (shaft diameter, OD, length, load ratings etc.) by model code.

Long Service Life

Stable load with evenly distributed ball force; selected bearing steel resists fatigue and extends equipment service life.

Quiet Operation

Circulating balls deliver smooth reciprocating motion, reducing metal friction noise and keeping operation quiet at high speed.

Precise Tolerance

Strict dimensional tolerance control gives excellent bore accuracy, uniform clearance with the guide shaft and high positioning precision.

Low-Friction Travel

A closed ball-circulation structure keeps rolling friction low, making reciprocating motion light and responsive with less drive loss.
