Product Description

Center Round Flange Linear Bearing with Motion Balls

The middle flanged type linear bearing has a flange that is located in the center of the product. With good interchangeability, the flange can be repaired and replaced very conveniently. This makes it suitable for load bearing and long stroke applications. In addition, the flange used for fixing has square, round and oval shapes. It should be taken into account that the inner bore of the coupled equipment should be accurate enough to facilitate installation.
Features
The middle flanged type linear bearing produces no noise due to the small coefficient of friction during working. It also travels with high stability because of the stabilized flange. While maintaining high precision, the product can also be replaced with ease.
Applications
The product has found wide applications in a variety of machinery, such as the printers, multi-axis lathes, electric power tools, Computerized Numerical Control (CNC) machine tools, and so on.
This series of middle flanged type linear bearing includes the major components of sleeve, cage, ball, flange, and seal. LMFM, LMEFM, and LMBFM series are separately produced in compliance with the standards in Asia, Europe, and the Americas. Just in the same case, LMKM, LMEKM, and LMBKM also respectively conforms to the above-mentioned standards in those three regions. The difference between LMFM, LMKM, and LMHM is the flange shape, corresponding to round flange, square flange, and oval flang
