Ball recirculation bushings and sleeves
THK, LM Linear Ball Bushings and Sleeves
The ball screw is a linear motion system that, when combined with an LM cylindrical shaft, enables linear motion with minimal friction, ensuring precise, smooth, and seamless movement. Thanks to these features, it is an ideal solution for applications that require high positioning accuracy and reliability.
The LM linear bushing consists of a sleeve with grooves arranged in a semicircle, within which the load-bearing balls slide. These are guided in sequence by a stop integrated into the nut, which ensures their uniform movement along the longitudinal direction of the shaft.
Made of high-carbon bearing steel that has been heat-treated and subsequently ground both internally and externally, the bushing ensures high hardness, wear resistance, and a long service life.
Linear ball recirculation sleeves
LM Series, LM-GA, LM-MG, LME, LM-L
These cylindrical linear guide models feature a simple, high-precision surface.
The bushing can be used for a wide range of applications and is available in the series listed below, which are classified by size.
Flanged linear ball joint
LMF, LMF-M, LMK, LMK-M, LMF-L, LMF-ML, LMK-L, LMK-ML, LMH, LMH-L series
The sleeve is equipped with a flange. This allows it to be mounted directly onto the housing using screws, thereby simplifying installation.
Linear ball bearing sleeve
SC, SL, SH, SH-L Series
Since the lightweight, compact aluminum frame houses one LM-model unit and two SL-model units, it can be easily mounted by securing it to the table with screws.
LM Shaft Support
SK Series
A lightweight aluminum pivot for securing the LM shaft. Since the mounting section of the LM shaft has a slot, the pivot can be securely fastened to the LM shaft using bolts.
