The ball runner block made of Resist NRII is corrosion-resistant and highly precise. Additionally, it is characterized by the following product features:
Size 20
Format SNS: Width = slimline, length = normal, height = standard
Runner block body and all steel components made of corrosion-resistant steel as per DIN 10088
Preload class C1: Low preload
Accuracy class H: High
With ball chain
Without preservation
Without initial lubrication
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 = 75.0 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
- Long-term lubrication is possible over several years
- All metal parts are made of corrosion resistant steel
- Significantly reduced frictional oscillations and low friction force level, particularly under external load
- Patented entry zone increases the travel accuracy up to a factor of six
- Can be used on all SNS ball guide rails
- Available in five common sizes
- Lube fittings with metal threads on all sides
- Attachments on the ball runner block can be mounted from above
- The same high load ratings in all four main directions of loading
- Minimum quantity lubrication system with integrated reservoir for oil lubrication
- Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
- Excellent dynamic characteristics
- Integrated all-round sealing
- Ball chain for low noise level and best travel behavior
