Applicable Tubing Specifications Rotating Torque/Allowable Number of Rotations Principal Parts Material Tubing material Tubing O.D. FEP, PFA, Nylon, Soft nylon, Polyurethane o4, o6, o8, o10, o12 Note 1) Please avoid using in a vacuum holding application such as a leak tester, since there is leakage. Also, when using in a vacuum, grease may enter the inside due to the nature of its construction.

Bearing steel Series KX FKM . NBR Ball bearing Stainless steel 440C Gasket Stainless steel 304, NBR Slide bearing Smooth operation and longer life from an oil containing slide bearing. Cassette The male connector is equipped with a “tuberotation prevention mechanism”. Series KS Blue Series KX Light grey Rotary seal A special rotary seal minimizes friction while providing an excellent seal. Scraper Prevents chips from intruding into bearing parts. Ball bearing Holder Standard nickel plated allows copper-free applications. Ball bearing A ball bearing ensures low torque rotation. Stud �� Electroless nickel plated �� With thread sealant (R thread only) Series KX (High speed) Series KS (Standard) . Other parts’ specifications are same as those of Series KS. A ball bearing ensures low torque rotation. Stainless steel 440C improves corrosion resistance. X ring shape minimizes friction while providing an excellent seal. Seal is fire and shock proof fluorine rubber. Proves against high friction heat in high speed rotation and longer life. Rotary seal Low torque rotation style Rotary One-touch fittings Applicable to use for oscillating and rotating sections in robots. Copper-free specifications Brass parts are all electroless nickel plated. Sealant is standard. Male connector Male elbow Rotary One-touch Fittings Standard Type/High Speed Type Series KS/KX RoHS 114
