Product Description
The self-adjusting ball runner block compensates for alignment errors of up to 10’. Additionally, it is characterized by the following product features:
Size 25
Format SKS: Width = slimline, length = short, height = standard
Runner block body made of carbon steel CS
Preload class C0: Preload-free
Accuracy class N: Normal
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<sup></sup>
- Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class.
- Extra-compact design
- 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
- Can be used on all SNS ball guide rails
