Linear bearing LMKC...L series is also known as long centered square flange linear bearings LMKC...L, and code L stands for the lengthen type. This type linear bearing bushing has a square flange positioned in the center of its outer sleeve, and the bushing parts on both sides of the flange have the same length.


The square flange is matched with the corresponding fittings to make the shaft positioning simple. It does not need to be fixed in the matching bearing housing. Therefore, it becomes very economical and reduces the overall weight of assembly. Moreover, with its good interchangeability, it widely uses for load bearing and long stroke applications.


There are several shapes for middle flanged type linear bearings, square, round and oval, while the flange of LMKC series is in square shape. Moreover, the user should be taken into consideration that the inner bore of the coupled equipment should be accurate enough to facilitate installation.



The flange linear bearings can be used in a wide variety of applications, including transportation equipment, food processing equipment, office equipment, dental drills, stepper motors, video recorder drums, fans, pulleys, rollers, robots, medical equipment, semiconductor manufacturing equipment and other machinery.
