Ball runner block, CNS, size 20, steel CS, accuracy standard, low preload, with ball chain Product Description The ball runner block is highly precise and characterized by the following product features: Size 20 Format CNS: Width = compact, length = normal, height = standard Runner block body made of unalloyed steel CS Preload class C1: Low preload Accuracy class N: Standard With ball chain With initial lubrication and preservation Roller bearing grease Dynalub 510 Without attachment element, left (front reference edge) Without attachment element, right (front reference edge) Straight lube connection loosely attached. Runner block body in standard version Overall length of the runner block = 73.0 mm Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy. 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 load capacity Attachments on the ball runner block can be mounted from above Integrated all-round sealing Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block Can be used on all BNS ball guide rails Wide range of accessories End-face fastening thread for all attachments Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection Quiet, smooth running thanks to optimally designed ball and ball chain return and guideway Maximum system rigidity due to preloaded O-arrangement Very high torsional moment load capacity and very high torsion resistance – therefore primarily used as an individual guide Ball chain for low noise level and best travel behavior Ball runner block pre-lubricated at the factory Technical Specs Product attributes Version Ball rail system Nominal size [mm] 20/40 Format CNS - compact, normal, standard height Model Wide ball runner block Material (profiled rail systems) Carbon steel Preload class C1 - Low preload Accuracy class N - Normal Seal SS - Standard seal Ball chain With ball chain Self-aligning for compensation of misalignments Without self-alignment Width of runner block [mm] 62 Length of runner block [mm] 73 Height of runner block [mm] 22.5 Height runner block with guide rail [mm] 27 Lubrication With initial lubrication and preservation Maximum acceleration rate amax [m/s²] 500 Note: Max. acceleration amax If Fcomb◡> 2.8 • Fpr : amax = 50 m/s2 Maximum permissible linear speed vmax [m/s] 5 Permissible ambient temperature (min. ... max.) ​0 °C ... +80 °C Note: permissible ambient temperature (min. ... max.) 100 °C admissible for short time.
