BKL Brand closed linear ball bushing with resin retainer and two rubber seals 40mm inside x 60mm outside x 80mm long, also known as SM40GUU, LBD40UU, LB40NYDD, N40VUU, L40UU, TB40UU
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.
