What is the Bosch Rexroth R20008130X?

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 FKS: Width = flange, length = short, 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

Without 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 = 57.3 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 longitudinal direction

Integrated all-round sealing

Maximum system rigidity due to preloaded O-arrangement

All metal parts are made of corrosion resistant steel

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

The same high load ratings in all four main directions of loading

High rigidity in all load directions – permits applications with just one runner block per rail

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

Significantly reduced frictional oscillations and low friction force level, particularly under external load
