What is the Bosch Rexroth R166229371?
The self-adjusting ball runner block compensates for alignment errors of up to 10’. It is corrosion-resistant thanks to its Resist CR coating. Additionally, it is characterized by the following product features:
Size 25
Format SKS: Width = slimline, length = short, height = standard
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
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 = 67.0 mm
Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
Area of application: For compensating large tolerances in the adjoining structure
Low noise level and outstanding travel behavior
Excellent dynamic characteristics
Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class.
Steel ball runner block body with corrosion-resistant coating, matt silver finish, hard chrome plated
Compensates own misalignments (for deviations up to 10' in 2 levels)
The same high load ratings in all four main directions of loading
Lube fittings with metal threads on all sides
Smooth operation due to optimal return and ball pick-up and entry design
Preload classes: C0 (without preload, clearance) and C1 (moderate preload)
Enables greater parallelism and height offsets of mounting bases
Extra-compact design
