Cheap Ball Units SMA8UU Aluminium Motion Bearing Shaft Support Sk20 Slide Sbr20 Linear Case Unit
Product Description of linear motion bearing
Product Description
This is a case unit with the standard linear bearing installed in a small and light aluminum case.
The slide unit series is a line of standardized slide bearing housings and shaft supporters to enable smooth linear motion using slide bearings and shafts. slide units are designed to optimize the performance of all slide bearings including clearance-adjustable and open types. These slide units are made mainly of aluminum, providing high corrosion resistance.

Feature
1. Dynamic and static friction resistance difference is small,
which is helpful to improve the response speed and sensitivity of
CNC system.
2. The driving power is small, which reduces the energy
consumption.
3. High positioning accuracy and repeat positioning accuracy.
4. By increasing the preload, the rigidity is greatly enhanced.
5. Using paired guide rais, it has the effect of homogenizing
error.
6. Can withstand the load from up and down or so.
7. The end and the side can be manual or automatic lubricated
through oil cup.
8. It has simplified the design and manufacture of mechanical
structure, therefore reduced themanufacturing cost.
