Description

The ball runner block is highly precise and characterized by the following product features:
Size 55
Design FNS: Width = flange, length = normal, height = standard
Runner block body made of carbon steel CS
Preload class C0: Preload-free
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 = 159,0 mm
Interchangeability: The runner blocks and the guide rails can be combined as desired within each accuracy class.

Area of application: For high rigidity requirements
Top rigidity in all load directions
High torque capacity

Specifications

Height of runner block with guide rail [mm]: 70 Lubrication: Preserved and without prelubrication Dynamic load capacity C [N]: 109000 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]: 3480 Dynamic longitudinal moment load capacity ML [Nm]: 2320 Static longitudinal moment load capacity ML0 [Nm]: 3690 Static torsional moment load capacity Mt0 [Nm]: 5550 Max. acceleration amax [m/s²]: 250 Seal: SS - Standard seal Static load rating C0 [N]: 174000 Permissible ambient temperature: -10 °C ... +80 °C Pitch T guide rail [mm]: 120 Height of runner block: 57 Friction coefficient μ: 0,002 ... 0,003 Weight [kg]: 5.02
