The aluminum ball runner block is highly precise and has a reduced weight compared to the steel version. Additionally, it is characterized by the following product features:
Size 20
Format SNS: Width = slimline, length = normal, height = standard
Runner block body made of aluminum
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 = 75.0 mm
Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
- Area of application: For lightweight design – for compensating low tolerances with connected structures
- Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
- Extra-compact lightweight design 60% less gravity due to aluminum compared to the ball runner blocks made of steel
- Maximum precision
- Patented entry zone increases the travel accuracy up to a factor of six
- Can be used on all SNS ball guide rails
- Lube connection with metal thread on all sides
- Ball runner block pre-lubricated at the factory
- Attachments on the ball runner block can be mounted from above
- Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class.
- Excellent dynamic characteristics
- Minimum quantity lubrication with integrated reservoir for oil lubrication
- Predrilled holes on the Ball Runner Block for pinned fitting
- Enables greater parallelism and height offsets of mounting bases
- Long-term lubrication is possible over several years
- Accuracy classes H and N are combinable with all rails in each accuracy class
