The structure of linear motion ball bearing is that in the outer ring of the cage, the cage equipped with a number of steel balls, and the infinite loop movement. Both ends of the retainer within the spring retaining ring in force straight track side of each steel ball have a notch window. This section is for rolling contact with the ball and shaft load. Relative movement with a very low coefficient of friction, linear motion ball bearings for machinery and equipment, automation equipment, energy-saving equipment is the most appropriate selection of the bearing.

Linear motion bearing is increasingly widely used in electronics, machinery, instruments, robots, tools, machinery, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, CNC machine tools, automobile and other general or special machinery industry.

The advantage of linear motion bearings:

1. Mobile contact allows starting friction resistance and dynamic frictional resistance to a very small, so you can save energy, easy to get a higher speed of movement.

2. Load increases, the friction coefficient not sensitive to changes, under heavy load, the friction coefficient is extremely small, and the long-term to maintain the accuracy of the same machinery life long.

3. Linear motion bearings good interchangeability, province to install and easy to use, and the mechanical structure of the novel, small, lightweight characteristics.

4. Savings to the procedures for oil, simplify lubrication and maintenance purposes.

5. Place on both sides of the additional oil seal bearing also suitable for dusty or foreign objects easily penetrated.

Classification of linear motion ball bearings

Standard series most widely used of three different sizes:

LM series: metric size series (Southeast Asian countries to use); LME Series: Metric size series (U.S. only). l micro adapt to light, thin, short, the needs of the age of the series, the ultra-small diameter size, inner diameter: 3,4, 5MM. Stainless steel outer ring, steel balls at both ends of the cover are stainless steel retainer plastic manufacturing.

S, SL .... UUl open-ended removal of a ball, and the corresponding outer ring, high rigidity can be obtained, and to prevent the shaft warpage guide mechanism, adjustable gap can be obtained at the same time, no loose fitting state.

LM .... OP LME .... OP gap in the outer ring on adjustable along the long axis of the open with a single seam type, to adjust the fixed bearing housing to fit, no loose state.

The LM .... ADJ LME .... the ADJ attached oil seal type bearing single-ended or at both ends with a special synthetic rubber seal lip, suitable for dusty and foreign body penetrated place, and keep lubricantsdoes not leak.
