Wózki liniowe
The ball runner block is highly precise and characterized by the following product features:
Size 25
Design FNN: Width = flange, length = normal, height = low
Runner block body made of carbon steel CS
Preload class C1: Low preload
Accuracy class N: Normal
Without ball chain
With preservation
Without initial lubrication
Without attachment element, left (reference edge in front)
Without attachment element, right (reference edge in front)
45° angular lube nipples loosely attached.
Runner block body as standard version
Overall length of the runner block =81,0 mm
Interchangeability: The runner blocks and the guide rails can be combined as desired within each accuracy class.
- 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
