The ball runner block is highly precise and characterized by the following product features:
Size 25
Format SNH: Width = slimline, length = normal, height = high
Runner block body made of unalloyed steel CS
Preload class C1: Low preload
Accuracy class P: Precision
With ball chain
With initial lubrication and preservation
Roller bearing grease Dynalub 510
Without attachment element, left (front reference edge)
Without attachment element, right (front reference edge)
Straight lube connection loosely attached.
Runner block body in standard version
Overall length of the runner block = 86.2 mm
Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
- Area of application: For restricted space in the transverse direction and high rigidity requirements
- Higher rigidity than SNS
- Significantly reduced frictional oscillations and low friction force level, particularly under external load
- Maximum precision
- Patented entry zone increases the travel accuracy up to a factor of six
- High rigidity in all load directions – permits applications with just one runner block per rail
- High torque load capacity
- Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class.
- Long-term lubrication is possible over several years
- End-face fastening thread for all attachments
- Quiet, smooth running thanks to optimally designed ball and ball chain return and guideway
- Different preload classes
- Excellent dynamic characteristics
- Can be used on all SNS/SNO ball guide rails
- Ball runner block pre-lubricated at the factory
- Ball chain for low noise level and best travel behavior
