∗ 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.

1. Implement the tube piping in such a way that lateral load should not be applied on the ball bearings at the rotating part, otherwise it may adversely affect the life expectancy.A flexible polyurethane tube is recommended when lateral load is applied.

2. Do not use in an environment where it will be exposed to water.Contact with water will cause outflow of the lubricating oil used in the ball bearings, and adversely affect rotating performance and equipment lifespan.

3. Fluorine grease is used on the rotating portions.

Be sure to read before handling.Refer to front matters 58 and 59 for Safety Instructions and pages 13 to 16 for Fittings and Tubing Precautions.
