Description

The ball runner block is highly precise and characterized by the following product features:
Size 20
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 =72,5 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 level, particularly under external load
Long-term lubrication is possible over several years

Specifications

Height of runner block with guide rail [mm]: 28 Lubrication: Preserved and without prelubrication Dynamic load capacity C [N]: 14500 Footnote dynamic load capacity C: The calculation of the dynamic load ratings and load moments is based on a stroke length of 100,000 m as per DIN ISO 14728-1. However, often only 50,000 m is actually stipulated. For comparison: Multiply the values C,Mt and ML from the table by 1.26. Dynamic torsional moment load capacity Mt [Nm]: 190 Dynamic longitudinal moment load capacity ML [Nm]: 100 Static longitudinal moment load capacity ML0 [Nm]: 165 Static torsional moment load capacity Mt0 [Nm]: 310 Max. acceleration amax [m/s²]: 250 Seal: SS - Standard seal Static load rating C0 [N]: 24400 Permissible ambient temperature: -10 °C ... +80 °C Pitch T guide rail [mm]: 60 Friction coefficient μ: 0,002 ... 0,003 Height of runner block: 23 Weight [kg]: 0.373329
