More Details
The Caged Ball Chain Design provides lower friction and lower noise than traditional profile rail block designs. The benefit of a caged ball design prevents the bearings from incidental contact, which reduces friction, wear and noise.
Rotational Ball Chain:
- Reduces noise
- Higher speed in motion
- Prolong service life
- Prolong re-lubrication period
A uniquely patented ball chain design provides a flexible link between the block and bearings. This gives the ball chain enough space to rotate and move in the circulation channel and overcome the friction of the curvature. In addition, the space between upper and bottom parts have oil storage functions, increasing the re-lubrication interval and service life.
