The ball runner block is highly precise and characterized by the following product features: Size 20 Format BNS: Width = wide, length = normal, height = standard Runner block body made of unalloyed steel CS Preload class C0: Preload-free Accuracy class N: Standard Without 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 • The same high load ratings in all four main directions of loading • Long-term lubrication is possible over several years • Excellent dynamic characteristics • Attachments on the ball runner block can be mounted from above and below • High torque load capacity • 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 • Lube connection with metal thread on all sides • Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection • 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
