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 H: High 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
