Overview for Rotary Joint SMQR
QR type rotary joint adopts imported mechanical seal combined with a silicon carbide ring. The auxiliary seal is made of Japanese silicone rubber. It can withstand 300°C high temperature and solve the problem of leakage for domestic hot oil equipment. Double bearing support solves the problem that it is difficult to find the installation balance point. It can be repaired directly on the equipment and does not need to be removed. The rotation speed is up to 5000 rpm. The pressure is 60 MPa.

Note 1) The temperature of 80 °C includes the temperature-rise value during rotation.
Note 2) The rotation torque does not change with the supply pressure or placement (within the allowable rotation torque), but the speed will change.
Note 3) If the speed is above 600 min-1 (r.p.m.), make sure to rotate in the direction of tightening the connector.
Note 4) Rubber / resin couplings are recommended because they have excellent absorption of eccentricity, shock and vibration.
