The rectilinear motion bearing is a kind of rectilinear motion system by low-cost production, used in the limitless journey and use with round axis of a cylinder. Because of bear the weight of ball with axle, present, order, keep in touch, use load to be little. The steel ball is rotated with minimum friction resistance, thus can obtain the steady sports of high precision.

Characteristic
The rectilinear motion bearing is a kind of rectilinear motion system by low-cost production, used in the limitless journey and use with round axis of a cylinder.
Because of bear the weight of ball with axle, present, order, keep in touch, use load to be little. The steel ball is rotated with minimum friction resistance, thus can obtain the steady sports of high precision.
Type
Normal form
The most popular series have three kinds of different size series:
Series LM: Series of metric size The country in Southeast Asia uses
Series LME: Series of metric size U.S.A. uses
Miniature
It is light, thin, short and small to suit, the series of the demand of era, small ultra diameter measurement, the internal diameter is as follows, 3, 4, 5 MM .
Stainless steel type
Outer lane, both ends of steel ball are sealed and covered as the stainless steel, the keepers adopts the plastics.
Style of opening
Excise a steel ball, and corresponding outer lane, can obtain high rigidity, and prevent the guide organization of axle warping, can receive interval controllability at the same time, has not become flexible to cooperate with the state.
LM OP LME OP
Interval adjusting type
Along having a form that sews the pattern axially long on the outer lane, the outer cover by adjusting the fixed bearing reaches and cooperates, have not loosened the state.
LM ADJ LME ADJ
Oil seal enclosing type
It has special synthetic rubber to seal the circle that bearing single-end or both ends is equipped with the lip type, more and foreign matter invades the place to suitable for dusts, the maintenance lubricating oil that and can be very good is not let out.
Advantage used
1 . Because of flow, exposed to, can make starting grit resistance and move, grit resistance as minimum, so can save energies, receive higher movement speed easily.
2 . Increase to load, but does not have sensitive change to grit the coefficient, so heavy load is carried on one’s shoulder or back and increased, grit the coefficient minima, and keep the precision not changing for a long time and get mechanical service life to keep for a long time.
3 . The intersection of rectilinear motion and bearing interchangeability fine, installation use instead save time while being convenient, and make the mechanical structure novel, small-scale, the characteristic that quantity is light.
4 . Give the procedure sparingly, achieve the goal of simplified and lubricated and is maintainedding.
5 . Both sides add the oil-sealed bearing and still adapt to employing more or place apt to invade of foreign matter with dusts.
