Specifications

Area of application: For maximum speeds
Maximum system rigidity due to pre-tensioned O-arrangement
Electrically insulating due to use of ceramic balls
High speed thanks to the low weight of ceramic balls
Attachments on the Ball Runner Block can be mounted from above

Ball Runner Blocks Resist NR II made of corrosion-resistant steel are used particularly in applications involving waterbased media. They are also suitable for environments with a relative humidity of over 70% and temperatures above 30 °C
