Description
Specifications
Height of runner block with guide rail [mm]: 30
Lubrication: Whitout prelubrication and not preserved
Dynamic load capacity C [N]: 16000
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.
