SMC KS/KX Rotary One-touch Fitting (Standard / High-speed)

SMC KS/KX Rotary One-touch Fitting (Standard / High-speed)

SMC KS (standard) and KX (high-speed) rotary one-touch fittings with ball bearings and a low-friction rotary seal for tube connections on rotating and swinging robot parts.

Key features

  • Ball bearing and special rotary seal give low rotating torque (0.006 to 0.022 N·m at 0.5 MPa)
  • KS standard type with oil-impregnated plain bearing: allowable speed 4.2 to 8.4 rps
  • KX high-speed type with FKM X-ring seal, scraper and SUS440C bearings: allowable speed 16.7 to 25 rps
  • Male connector (KSH/KXH, with tube anti-rotation) and male elbow (KSL/KXL) types
  • Brass parts electroless nickel plated; sealant on R threads as standard
