日本SHOWA-SEIK昭和旋转接头NRJ-TS-04x03R/NRJ-TS-06x04R Aluminum alloy is used for a casing. Installation to a roll is easy as this product is small and lightweight. As a grease-sealed ball bearings are used, greasing is not required. Due to low torque, a measure for preventing casing rotation is not required. ※We are also able to produce products with linear flow passages. ※We are also able to produce products available for dry air. Fluid Air / Gas / Water / Oil Max. Pressure 0.98MPa (142 psi) Max. Temperature 100 degrees C (212 degrees F) Max.
