Features of the Rosa Sistemi guide rail in Italy:

1. Smooth motion:

Less sliding can achieve smooth movement, reduce overheating, and extend service life.

2. Installation surface accuracy:

When the ball is deformed by elastic force, the arc can better adjust the installation error, thereby not affecting the smoothness and smoothness of movement.

3. Low running resistance:

When the two contact points of the arc structure are preloaded to increase its stiffness, the motion resistance remains unchanged.

4. High load-bearing capacity:

The curvature radius of the rolling surface varies between 52% and 53% of the ball diameter, resulting in a high specific bearing capacity.
