The ball runner block is highly precise and characterized by the following product features:
Size 20
Format FNN: Width = flange, length = normal, height = low
Runner block body made of unalloyed steel CS
Preload class C0: Preload-free
Accuracy class N: Standard
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 = 72.5 mm
Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy.
- Area of application: For restricted upward space
- Maximum precision
- Patented entry zone increases the travel accuracy up to a factor of six
- Significantly reduced frictional oscillations and low friction force level, particularly under external load
- Long-term lubrication is possible over several years
- Lube fittings with metal threads on all sides
- End-face fastening thread for all attachments
- Integrated all-round sealing
- High torque load capacity
- Preload classes: C0 (without preload, clearance) and C1 (moderate preload)
- Optional integrated, inductive and wear-free measuring system
- Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
- Can be used on all SNS/SNO ball guide rails
- Attachments on the ball runner block can be mounted from above and below
