Ball runner block (self-aligning), FKS, size 20, Resist CR – coating, accuracy high, preload-free, without ball chain

The self-adjusting ball runner block compensates for alignment errors of up to 10’. It is corrosion-resistant thanks to its Resist CR coating. Additionally, it is characterized by the following product features:<br>Size 20<br>Format FKS: Width = flange, length = short, 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>Without 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 = 57.3 mm<br>Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy. Area of application: For compensating large tolerances in the adjoining structure Low noise level and outstanding travel behavior The same high load ratings in all four main directions of loading Steel ball runner block body with corrosion-resistant coating, matt silver finish, hard chrome plated Limitless interchangeability as all ball guide rail systems can be combined at will with all ball runner block versions within each accuracy class. Attachments on the ball runner block can be mounted from above and below Long-term lubrication is possible over several years Excellent dynamic characteristics Extra-compact design Compensates own misalignments (for deviations up to 10' in 2 levels) Enables greater parallelism and height offsets of mounting bases Lube fittings with metal threads on all sides Preload classes: C0 (without preload, clearance) and C1 (moderate preload) Ball runner block pre-lubricated at the factory
