Long-Term Maintenance-free Operation

Long-term maintenance-free operation has been achieved by the adoption of the Caged Ball LM Guide SRS* and the QZ Lubricator, which supplies the optimal amount of lubricant to the ball screw.

* VLAST only.

The QZ Lubricator feeds the right amount of lubricant to the ball screw shaft raceway.
This allows an oil film to be constantly formed between the balls and the raceway, which improves the lubricity and significantly extends the maintenance interval.
