BK Rotary Union Series
● BK rotary union is generally multi-spring design structure provides stable spring force for the sealing surface
● Balanced mechanical seal design structure reduces the impact of pressure change load on the sealing surface and extends service life
● BK rotary union supported by two large imported high-temperature bearings so that the rotation is stable
● Specially spacer design structure prevents high temperature from being directly transmitted to the bearing surface, extending the bearing life
● Modular structure to avoid bearing jamming due to seal failure and thermal oil leakage to the bearing and coking.
● BK rotary union shell is equipped with an observation hole to observe leakage and friction
Please contact us immediately if you have special needs, our sales engineers can recommend slip ring models or design customized slip rings for you.

BK Rotary Union Notes
● When the rotary union working temperature is +230°C~+300°C, please reach out to WAYDUN for further information
● Please make sure one drainage hole is vertically downwards; And please use hoses to channel the leaked hot oil to safe place
