KWD-020-SNS-C0-N-1, Bosch Rexroth , Ball runner block, SNS, aluminium, accuracy standard, preload-free, without ball chain

• 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 aluminium 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
• Ball runner block pre-lubricated at the factory
• Attachments on the ball runner block can be mounted from above
• Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class.
• Excellent dynamic characteristics
• 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
Long-term lubrication is possible over several years
