SBR20UU Good Quality and Long Life Bearing SBR20UU Linear Motion Slide Block Bearing SBR20UU

Bearing Description:

Structure and features of linear bearing is a shell, special ball, retainer ring or a ring with both ends of the card formed. Cage within the device in the case, from both ends of the clasp or ring fixed to ball in the cage track surface a repeating cycle of movement. And shell after adequate heat treatment to a certain level of hardness, to ensure the accuracy and stability of movement and life. Ball cage formed by the nylon resin injection pressure, which can reduce the ball and the retainer between the noise and wear, and play the guiding role of accurate, linear bearings allow the use of the temperature is 80 or less.
1. Linear bearing is a low cost production of linear motion systems, for unlimited travel in conjunction with the cylinder axis. 
2. As was carrying the ball with the axis point of contact, so use small loads. 
3. Ball rotation with minimal friction , which can get a smooth precision movement. 

Drawing:

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.

Linear bearings are widely used in electronic equipment, tensile testing machine and the digital three-dimensional coordinate measuring equipment, precision equipment, and multi axis machine tools, presses, tool grinder, automatic gas cutting machine, printer, card sorting machine, food packing machines and other industrial machinery sliding components.
