The advantages of miniature bearings:
1. As a result of the flow contact can make the starting friction resistance and the dynamic friction resistance is extremely small, therefore may save the energy, easy to obtain the high movement speed.
2. The load increases, but the friction coefficient is not sensitive to change, so the heavy load, the friction coefficient is very small, and long-term accuracy to maintain the same mechanical life can be maintained long-term.
3. Linear motion bearings interchangeable, easy to install and save time, and the mechanical structure of new, small, light weight characteristics.
4. To save oil procedures, to simplify the purpose of lubrication and maintenance.
5. Both sides of the bearing with oil seal also applies to more dust or foreign body easy to invade the place.

Miniature bearing classification: standard The most widely used series has three different size series: miniature to adapt to the light, thin, short, times the demand for the series, ultra-small diameter size, diameter: 3,4,5 MM. L stainless steel outer ring, both ends of the steel ball cap are stainless steel, the holder is made of plastic. S, SL ... UU l Open cut a row of steel ball, and corresponding to the outer ring, can get high rigidity, and to prevent the guide shaft guide mechanism, and can be adjustable gap, no loose with the state. LM ... OP LME ... OP l gap adjustment type in the outer ring along the long axis to open a single seam type to adjust the fixed bearing shell to fit, no loose state. LM ... ADJ LME ... ADJ l with oil seal bearings with single-ended or both ends of the lip with a special synthetic rubber seals, suitable for more dust and foreign bodies into the place, and can be very good to keep the oil does not leak.
