Bosch Rexroth R165381420

Ball runner block, FLS, size 20, steel CS, accuracy standard, low preload, without ball chain The ball runner block is highly precise and characterized by the following product features:Size 20Format FLS: Width = flange, length = long, height = standardRunner block body made of unalloyed steel CSPreload class C1: Low preloadAccuracy class N: StandardWithout ball chainWith initial lubrication and preservationRoller bearing grease Dynalub 510Without attachment element, left (front reference edge)Without attachment element, right (front reference edge)Straight lube connection loosely attached.Runner block body in standard versionOverall length of the runner block = 91.0 mmInterchangeability: The runner block and the guide rails can be combined with each other with every accuracy. - Area of application: For the most demanding rigidity requirements - Significantly reduced frictional oscillations and low friction force level, particularly under external load - Excellent dynamic characteristics - Maximum precision - Patented entry zone increases the travel accuracy up to a factor of six - Long-term lubrication is possible over several years - Lube fittings with metal threads on all sides - End-face fastening thread for all attachments - Integrated all-round sealing - High torque load capacity - Different preload classes - High rigidity in all load directions – permits applications with just one runner block per rail - Improved rigidity under lift-off and side loading conditions...
