Ball runner block, FKN, size 25, steel CS, accuracy standard, preload-free, without ball chain

The ball runner block is highly precise and characterized by the following product features:<br>Size 25<br>Format FKN: Width = flange, length = short, height = low<br>Runner block body made of unalloyed steel CS<br>Preload class C0: Preload-free<br>Accuracy class N: Standard<br>Without ball chain<br>Preserved<br>Without initial lubrication<br>Without attachment element, left (front reference edge)<br>Without attachment element, right (front reference edge)<br>45° angular lube nipples loosely attached.<br>Runner block body in standard version<br>Overall length of the runner block = 62.0 mm<br>Interchangeability: The runner block and the guide rails can be combined with each other with every accuracy. Area of application: For cases of restricted space avialability in the upward and longitudinal direction Maximum precision Patented entry zone increases the travel accuracy up to a factor of six Significantly reduced frictional oscillations and low friction force level, particularly under external load Long-term lubrication is possible over several years Lube fittings with metal threads on all sides End-face fastening thread for all attachments Can be used on all SNS/SNO ball guide rails Integrated all-round sealing Preload classes: C0 (without preload, clearance) and C1 (moderate preload) Optional integrated, inductive and wear-free measuring system Optimized entry-zone geometry and high number of balls minimize variation in elastic deflection
