    SMC MQR Low-Torque Rotary Joint (Metal Seal, 1 to 16 Circuits)

    SMC MQR Low-Torque Rotary Joint (Metal Seal, 1 to 16 Circuits)

    SMC MQR series metal-seal rotary joints supply air through 1 to 16 independent circuits to rotating tables and robot arms with very low rotating torque and long life.

    Key features

    • Metal seal spool/sleeve construction: starting torque 0.003 to 0.50 N.m, unaffected by supply pressure or idle time
    • Long life: up to 1 billion rotations (MQR1) to 100 million rotations (MQR12/16)
    • Allowable speed 200 to 3000 rpm depending on circuits; usable from -100 kPa to 1.0 MPa
    • Spiral port layout makes tube bundling easy; body or adapter plate can be the driven side
    • Flange type (F) for 2 to 16 circuits; flange bracket also sold separately; not for torque transmission (use a flexible coupling)
