Linear Bushing LMK LMK30 LMK30UU Linear Bearing

Linear bearings are used in combination with linear guided shafts to perform infinite linear motion using the rolling of the steel balls. The steel balls are circulated along the track grooves formed by the housing and retainer, and the linear bearings achieve a linear motion of infinite travel with respect to the guide shaft. Compared to plain bearings, it can achieve low-friction and high-precision linear motion, and is used in a wide range of fields, such as conveyor equipment and semiconductor equipment.

• Since the dimensional tolerances of the parts of linear bearings are standard, they are interchangeable. The LM optical shaft utilizes a cylindrical grinding machine, which can be easily grinded and can obtain high-precision mating clearance.
• The retainer that guides 3~8 rows of steel balls is a monolithic casting structure, so it is possible to correctly guide the steel balls in the direction of movement of the steel balls, and it is possible to achieve stable walking accuracy.
• Small-diameter products use a synthetic resin retainer that is cast in one piece, which reduces noise during operation and has excellent lubrication effect.
• THK offers a wide range of types such as standard, adjustable clearance, open, long, flanged and flanged LM ball bushings, and users can choose the right type according to their application.
