Bosch Rexroth BALL RUNNER BLOCK RESIST CR KWC-020-SKN-C0-H-2
The ball runner block is highly precise and corrosion-resistant thanks to its Resist CR coating. Additionally, it is characterized by the following product features:. Size 20. Format SKN: Width = slimline, length = short, height = low. Runner block body made of unalloyed steel CS, matte-silver, hard chrome plated. Preload class C0: Preload-free. Accuracy class H: High. Without ball chain. Preserved. Without initial lubrication. Without attachment element, left (front reference edge). Without attachment element, right (front reference edge). 45° angular lube nipples loosely attached. Runner block body in standard version. Overall length of the runner block = 55.0 mm. Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy
