Ball runner block, SKN, size 20, Resist CR \u2013 coating, accuracy high, preload-free, without ball chain Product Description 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: Size 20 Format SKN: Width = slimline, length = short, height = low Runner block body made of unalloyed steel CS, matte-silver, hard chrome plated Preload class C0: Preload-free Accuracy class H: High 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 restricted space in the upward, longitudinal and transverse direction Maximum precision Significantly reduced frictional oscillations and low friction force level, particularly under external load Ball runner block body or ball guide rail made of steel with corrosion resistant coating, matte-silver finish, hard chrome plated Patented entry zone increases the travel accuracy up to a factor of six Long-term lubrication is possible over several years Excellent dynamic characteristics End-face fastening thread for all attachments Low noise level and outstanding travel behavior Ball runner block pre-lubricated at the factory Technical Specs Product attributes Version Ball rail system Nominal size [mm] 20 Format SKN - slimline, short, low Model High-precision ball runner block Material (profiled rail systems) Hard chrome plated Preload class C0 - Without preload (clearance) Accuracy class H - Highly accurate Seal SS - Standard seal Ball chain Without ball chain (standard) Self-aligning for compensation of misalignments Without self-alignment Width of runner block [mm] 42 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.
