| Area of application: For lightweight design – for compensating low tolerances with connected structures |
| Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection |
| Extra-compact lightweight design 60% less gravity due to aluminum compared to the ball runner blocks made of steel |
| Maximum precision |
| Patented entry zone increases the travel accuracy up to a factor of six |
| Can be used on all SNS ball guide rails |
| Lube connection with metal thread on all sides |
| Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block |
| Attachments on the ball runner block can be mounted from above and below |
| Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class. |
| Ball runner block pre-lubricated at the factory |
| Minimum quantity lubrication with integrated reservoir for oil lubrication |
| Predrilled holes on the Ball Runner Block for pinned fitting |
| Enables greater parallelism and height offsets of mounting bases |
| Smooth, quiet running thanks to optimally designed ball return and guideway |
| Accuracy classes H and N are combinable with all rails in each accuracy class |
| Long-term lubrication is possible over several years |
