The ball runner block is highly precise and characterized by the following product features:
Size 20
Design FLS: Width = flange, length = long, height = standard
Runner block body made of carbon steel CS
Preload class C0: Preload-free
Accuracy class H: High
With ball chain
With initial lubrication and preservation
Bearing grease Dynalub 510
Without attachment element, left (reference edge in front)
Without attachment element, right (reference edge in front)
Straight lube connection loosely attached.
Runner block body as standard version
Overall length of the runner block = 91,0 mm
Interchangeability: The runner blocks and the guide rails can be combined as desired within each accuracy class.
- Area of application: For the most demanding rigidity requirements
- Significantly reduced frictional oscillations and low friction force level, particularly under external load
- Excellent dynamic characteristics
- Maximum precision
- Patented entry zone increases the travel accuracy up to a factor of six
- Long-term lubrication is possible over several years
- Lube fittings with metal threads on all sides
- End-face fastening thread for all attachments
- Integrated all-round sealing
- High torque load capacity
- Different preload classes
- Ball chain for low noise level and best travel behavior
- High rigidity in all load directions – permits applications with just one runner block per rail
- Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block
- Maximum system rigidity due to preloaded O-arrangement
- Optional integrated, inductive and wear-free measuring system
- Attachments on the ball runner block can be mounted from above and below
- Ball runner block pre-lubricated at the factory
- Can be used on all SNS/SNO ball guide rails
- The same high load ratings in all four main directions of loading
