HW 215 R Thermal Oil Steam Rotary Joint
HW215R thermal oil & steam rotary joint is a direct replacement for Maier HW 215 R.
It adopts dual-channel design with cast iron housing and dome spherical sealing structure.
The sealing ring is made of antimony-impregnated graphite, featuring outstanding high temperature resistance and self-lubricating performance.
It is widely used for low-speed high-temperature equipment with thermal oil or saturated steam as medium.

product features
Dual independent passages separate inlet and return medium to avoid cross leakage and improve heat exchange efficiency
Dome spherical sealing structure provides automatic alignment compensation to maintain tight sealing under thermal deformation
Antimony-impregnated graphite seal ring has excellent wear resistance and high temperature stability against thermal oil and steam erosion
Rigid cast iron housing resists thermal stress and deformation during long-term continuous high-temperature operation
FAQ
A1: Higher density, better compression resistance and high temperature durability. It resists abrasion and carbonization under 250℃ working condition for longer service life.
A2: The spherical dome design allows slight axial and radial compensation, keeping the sealing surface fully attached even with roller thermal expansion and slight runout.
