Filton® Rotary P.B. Union
(Sizes 1/2" to 1")
Lubrication
The bellows seal or mechanical seal fitted to the rotary P.B. union is self-adjusting within its working life. The ball bearings are lubricated prior to shipping with a Bentone-base grease and occasionally require re-lubrication with a compatible grease; generally once per shift on “hot” applications and once per month on “cold” applications. For more specific recommendations, contact the grease manufacturer. Recommended lubricants include:
