PRODUCT

Linear bushing LM/LME presents most popular linear bearing in Europe. These types of linear bearings are widely used in different linear motion applications. LM/LME linear bushing has a steel outer ring with grooves for a circlip and a polyamide ball retainer with 3 to 6 ball circuits depending on size. On request linear ball bushing are also available in stainless steel. All linear bearings with the designation UU have seals from both sides.

 

 

JnSn linear bushing, LM type is the linear motion system with unlimited stroke by applying with LM shaft. Because of the point contact between balls and LM shaft, minimum friction can be acquired and that can give you the high precision motion. Linear bushing serves the alignment of the balls toward the LM shaft by the single retainer and cylindrical shape of raceway. Outer sleeve is made of bearing steel, and inner and outer grinding processes are applied after heat treatment.

 

 

Linear bearings are divided into two series according to the specification: LM and LME series. The linear bearing LM is a standard type. The code LM series is used in Asia, Southeast Asian countries, Japan, Korea, China, etc. In terms of metric size, the tolerance of the outer diameter of the linear shaft is generally h7. The LME series is mostly used in Europe, the United States, Germany, Italy and other regions. In the inch size, there are also metric sizes, and the tolerance of the outer diameter of the linear shaft is generally g6. Two series of structural features, in addition to different sizes, different aperture tolerances, the structure is roughly the same.

 

 

Application

Linear Bushing are widely used in precision equipment; computer and peripheral equipment, measuring equipment, auto recording equipment, and 3D measuring equipment, printing machines, food packing machines, auto-gas cutters and etc.
