Description
Specifications
Height of runner block with guide rail [mm]: 40
Dynamic load capacity C [N]: 28600
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 longitudinal moment load capacity ML [Nm]: 290
Static longitudinal moment load capacity ML0 [Nm]: 360
Static torsional moment load capacity Mt0 [Nm]: 510
Max. acceleration amax [m/s²]: 500
Static load rating C0 [N]: 35900
Permissible ambient temperature: -10 °C ... +80 °C
Friction coefficient ?: 0,002 ... 0,003
Height of runner block: 33.9
