Linear Bearing LM25

Descriptions of the bearing:
1) The Linear Bush is a linear guide used in combination with a LM shaft that has a cylindrical shaft.
2) This product makes linear movements with a minimum of frictional resistance to provide highly accurate and supple movement.
3) The linear ball bearing is consisted of an outer race, retainer, balls and end rings.
4) The retainers is incorporated inside the outer race, and has three or more rows of elliptical ball tracks that allow unlimited ball circulation and the balls circulate very smoothy in those ball tracks.
5) The retainer is held by two end rings at both ends of the outer race.
6) One side of the paralleled straight portions of the elliptical call track is cut off open, and the balls there are in contract with the shaft surface to circulate to and for unlimitedly in the ball trak according to the rectilinear reciprocation of the shaft. Thus the retainer forms rolling tracks, and at the same time keeps the balls from failing out when the bearing is removed from the shaft.

Application of the bearing:
Used for guiding, fixed machine parts, special equipment and instrument

Advantages of the bearing:
The cold press forming enable lightweight structure of the bearing.
The balls circulate endlessly.
Support heavy loads.
The bearing is interchangeable.
Can operacate with simple lubrication or without any lubrication, dependsing on applications.
Maintenance is almost free,
