What is the Bosch Rexroth R162252390?

The ball runner block is highly precise and enables very high travel speeds. Additionally, it is characterized by the following product features:

Size 55

Format SNS: Width = slimline, length = normal, height = standard

Runner block body made of unalloyed steel CS

Preload class C2: Medium preload

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 = 159.0 mm

Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.

Available in eight common sizes

Area of application: For maximum speeds

Maximum system rigidity due to preloaded O-arrangement

Electrically insulating due to use of ceramic balls

High speed thanks to the low weight of ceramic balls

Attachments on the ball runner block can be mounted from above

Lube fittings with metal threads on all sides

Can be used on all SNS/SNO ball guide rails

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

Long-term lubrication is possible over several years

Minimum quantity lubrication with integrated reservoir for oil lubrication

Smooth, quiet running thanks to optimally designed ball return and guideway

End-face fastening thread for all attachments

Ball runner block pre-lubricated at the factory
