Features
- Limitless interchangeability as all Ball 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.
- Excellent dynamic characteristics
- Can be used on all SNS/SNO Ball Guide Rails
- End-face fastening thread for all attachments
- Minimum quantity lubrication system with integrated reservoir for oil lubrication
- Integrated all-around sealing
- Attachments on the Ball Runner Block can be mounted from above
- Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
- Different preload classes
- The same high load ratings in all four main directions of loading
- High torque capacity
- For all SNS/SNO ball guide rails.
