Rotary joint rebuild, change seal ring only?-Image


It is important to change more than just the seal ring when the seal ring has reached its end of life. It is always a good practice to replace the "soft parts" in a rotary joint at the same time. Elastomeric seals can become inflexible and cracked after several years in service. Gasket surfaces should be cleaned and new gaskets installed. Internal seal pre-load springs can take a set, particularly in high-temperature applications. Replacing the springs, although not always required, is always a good idea. The associated metal parts can be re-used, often several times, but should be inspected for signs of wear or damage.
