Ball runner block, FKN, size 20, steel CS, accuracy standard, preload-free, without ball chain Product Description The ball runner block is highly precise and characterized by the following product features: Size 20 Format FKN: Width = flange, length = short, height = low Runner block body made of unalloyed steel CS Preload class C0: Preload-free Accuracy class N: Standard Without ball chain Preserved Without initial lubrication Without attachment element, left (front reference edge) Without attachment element, right (front reference edge) 45° angular lube nipples loosely attached. Runner block body in standard version Overall length of the runner block = 55.0 mm 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 Technical Specs Product attributes Version Ball rail system Nominal size [mm] 20 Format FKN - flange, short, low Model High-precision ball runner block Material (profiled rail systems) Carbon steel Preload class C0 - Without preload (clearance) Accuracy class N - Normal Seal SS - Standard seal Ball chain Without ball chain (standard) Self-aligning for compensation of misalignments Without self-alignment Width of runner block [mm] 59 Length of runner block [mm] 55 Height of runner block [mm] 23 Height runner block with guide rail [mm] 28 Lubrication With preservation and without initial lubrication Maximum acceleration rate amax [m/s²] 250 Note: Max. acceleration amax If Fcomb◡> 2.8 • Fpr : amax = 50 m/s2 Maximum permissible linear speed vmax [m/s] 3 Permissible ambient temperature (min. ... max.) -10 °C ... +80 °C Note: permissible ambient temperature (min. ... max.) 100 °C admissible for short time.
