Precautions
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.
Caution
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.
