Beskrivning
The LM Series linear ball bushing is a linear motion mechanism utilizing the rotational motion of ball elements. Since linear motion is obtained using a simple mechanism, the slide bush can be used in a wide variety of applications, including transportation equipment, food processing equipment, and semiconductor manufacturing equipment.
The outer cylinder of our LM ball bushings contains a resin ball retainer for low acoustic, low-cost requirement that is perfectly designed to control the circulation of ball elements, resulting in smooth linear motion.
Double lip-seals reduce the grease leakage, keeping the same function as UU seals which prevent the foreign particles from entering the bush.
Our Linear ball bushings are fully compatible with a variety of shaft types.
