Description Heavy-duty roller runner block for heavy machine construction with extremely high load capacity Top rigidity in all load directions Improved rigidity under lift-off and side loading conditions due to three additional mounting screw holes at the center of the roller runner block High torque capacity Limitless interchangeability and any number of combination options thanks to uniform roller guide rails in different versions across all roller runner block variants Features Attachments on the roller runner block can be mounted from above and below Lube ports on all sides for maximum ease of maintenance Minimum lubrication quantities thanks to innovative channel design Smooth running thanks to optimized roller recirculation and guidance Optimized entry-section geometry and high number of rollers per track minimizes variation in elastic deflection Aluminum end caps (size 125) and/or plastic (size 100) End seals integrated as standard for better sealing of all raceways and to protect plastic parts Product description Heavy-duty roller runner blocks are particularly suitable for heavy machine construction with very high carrying capacity- and rigidity requirements. Steel roller runner block with corrosion-resistant coating "Resist CR", matte silver finish, hard chrome plated Product description high-precision design Selection of a linear guide acc. to DIN 637 Technical data Load capacities and load moments Size 100 125 C N 632000 1020000 C0 N 1218000 1941900 Mt Nm 36400 57740 Mt0 Nm 71200 139820 ML Nm 27200 45080 ML0 Nm 52400 109150 Determination of the dynamic load ratings and load moments is based on a 100,000 m stroke in accordance with DIN ISO 14728-1. Often only 50,000 m are actually stipulated. For comparison: Multiply values C, Mt, and ML from the table by 1.23.
