The ball runner block is highly precise and characterized by the following product features:
Size 20
Format FNS: Width = flange, length = normal, height = standard
Runner block body made of unalloyed steel CS
Preload class C0: Preload-free
Accuracy class H: High
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 = 75.0 mm
Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.

Footnote dynamic load capacity C |
Determination of the dynamic load capacities and load moments is based on a 100 000 m travel as per DIN ISO 14728-1. Often only 50 000 m are actually stipulated. For comparison: Multiply values C, Mt and ML from the table by 1.26. |
