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 FKS: Width = flange, length = short, height = standard
Runner block body made of carbon steel CS
Preload class C1: Low preload
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
- The same high load ratings in all four main directions of loading
- Low noise level and outstanding travel behavior
- Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class.
- Smooth operation due to optimal return and ball pick-up and entry design
- Compensates own misalignments (for deviations up to 10' in 2 levels)
- Extra-compact design
- Enables greater parallelism and height offsets of mounting bases
- Accuracy classes H and N
- Preload classes: C0 (without preload, clearance) and C1 (moderate preload)
- Minimum quantity lubrication with integrated reservoir for oil lubrication
- Lube fittings with metal threads on all sides
- Excellent dynamic characteristics
- Can be used on all SNS ball guide rails
