The adjustable linear bearing LME...AJ is a metric unit series of cylindrical types commonly used in Europe, and bushing sleeve has a slit in the LM-shaft longitudinal direction based on the standard type for clearance adjustment. The code AJ stands for that this linear bearing type can adjust the tightness between the LM shaft and the linear bush. 

During the installation, this LME...AJ series can control the outer diameter, users can adjust the clearance based on the actual situation, so as to ensure the optimum working condition and achieve the best working efficiency. When a standard type product is installed onto the shaft, inappropriate clearance will cause damage, failure or unstable running to the linear motion bearing.

LME...AJ clearance-adjustable linear bearings are generally mounted to LME standard linear bearing pillow blocks, the linear shaft to be a simple linear motion system.


The linear bearing is generally applied to computer and peripheral equipment, measuring equipment, auto recording equipment, 3D measuring equipment, drilling machines, punching press, tool grinders, auto-gas cutters, printing machines, card selectors, food packing machines, and etc.
