Description
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 C2: Medium preload
Accuracy class N: Normal
Without 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.
Features
- Area of application: For restricted space in the transverse direction and high rigidity requirements
- 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
- Higher rigidity than SNS
