Product Description
The ball runner block made of Resist NRII is corrosion-resistant and highly precise. Additionally, it is characterized by the following product features:
Size 25
Format SKS: Width = slimline, length = short, height = standard
Runner block body and all steel components made of corrosion-resistant steel as per DIN 10088
Preload class C0: Preload-free
Accuracy class N: Standard
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 = 67.0 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 upward, longitudinal and transverse direction
- Long-term lubrication is possible over several years
- Ball runner block body and ball guide rail as well as all steel parts made of corrosion resistant steel in accordance with DIN EN 10088
- 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
- Maximum precision
- 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<sup></sup>
- Attachments on the ball runner block can be mounted from above
- Ball chain for low noise level and best travel behavior
