BALL RUNNER BLOCK CARBON STEEL KWD-025-CNS-C0-N-1 Bosch Rexroth

Ball Runner Block, CNS, Size 25, Steel CS, Accuracy Normal, Preload-Free

The ball runner block is highly precise and characterized by the following product features:
Size 25
Design CNS: Width = compact, 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 initial lubrication and preservation
Bearing grease Dynalub 510
Without attachment element, left (reference edge in front)
Without attachment element, right (reference edge in front)
Straight lube connection loosely attached.
Runner block body as standard version
Overall length of the runner block = 104,7 mm
Interchangeability: The runner blocks and the guide rails can be combined as desired within each accuracy class.

Area of application: For high torsional moments on rails with restricted lateral space
The same high load ratings in all four main directions of loading
Long-term lubrication is possible over several years
Excellent dynamic characteristics
High torque capacity

Height of runner block with guide rail [mm]: 35 Lubrication: Prelubricated and preserved Dynamic load capacity C [N]: 36200 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]: 1350 Dynamic longitudinal moment load capacity ML [Nm]: 490 Static longitudinal moment load capacity ML0 [Nm]: 680 Static torsional moment load capacity Mt0 [Nm]: 1870 Max. acceleration amax [m/s²]: 500 Seal: SS - Standard seal Static load rating C0 [N]: 50200 Permissible ambient temperature: -10 °C ... +80 °C Friction coefficient ?: 0,002 ... 0,003 Height of runner block: 29.75 Pitch T guide rail [mm]: 80 Weight [kg]: 1.12
