Two ball bearings, heat‑stabilised for series -800, factory‑lubricated, maintenance‑free up to 80 °C, for higher temperatures relubrication through easily accessible grease point required. Internal balanced mechanical seal. O‑rings Viton®. Additional axial shaft seal for bearing protection. Connection to rotating pressure system via standardized connection piece with sealing and centring face. Radial housing connection. ATEX certification optional. Five drain holes in housing, can be blocked with plugs in dusty environment.
Possible Applications
This rotary joint is specifically deployed in industrial thermal fluid systems where rotating machine components require a reliable transfer of high-temperature heat transfer media. Typical applications include calendar rolls in plastics processing, heated mixing drums in the rubber industry, and laminating or coating lines in film and paper manufacturing. The specialized sealing combination and heat-stabilized bearings enable continuous operation in these demanding thermal processes without fluid leakage or premature mechanical failure. Furthermore, the compact one-way flow architecture integrates seamlessly into tight machinery envelopes where space constraints preclude the use of multi-passage joints or external elbows.
