Ball runner block, BNS, size 20, Resist CR – coating, accuracy high, preload-free, with ball chain

The ball runner block is highly precise and corrosion-resistant thanks to its Resist CR coating. Additionally, it is characterized by the following product features:<br>Size 20<br>Format BNS: Width = wide, length = normal, height = standard<br>Runner block body made of unalloyed steel CS, matte-silver, hard chrome plated<br>Preload class C0: Preload-free<br>Accuracy class H: High<br>With ball chain<br>With initial lubrication and preservation<br>Roller bearing grease Dynalub 510<br>Without attachment element, left (front reference edge)<br>Without attachment element, right (front reference edge)<br>Straight lube connection loosely attached.<br>Runner block body in standard version<br>Overall length of the runner block = 73.0 mm<br>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 Excellent dynamic characteristics Ball runner block body or ball guide rail made of steel with corrosion resistant coating, matte-silver finish, hard chrome plated High torque load capacity Attachments on the ball runner block can be mounted from above and below End-face fastening thread for all attachments Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection Can be used on all BNS ball guide rails Maximum system rigidity due to preloaded O-arrangement Wide range of accessories Ball runner block pre-lubricated at the factory Improved rigidity under lift-off and side loading conditions due to two additional mounting screw holes at the center of the ball runner block Quiet, smooth running thanks to optimally designed ball and ball chain return and guideway 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
