Rotary joint

SMC's MQR rotary joint is now available to local manufacturers.

Claimed to be particularly valuable for manufacturers of rotary carousels, materials handling apparatus and high-speed rotating equipment, the MQR distributes compressed air, thus enabling supply tubes to be connected for various applications on rotating devices.

Inside the aluminium body, the glandless construction has eliminated the need for dynamic soft parts. The MQR's dynamic metal seal prevents sticking and makes the replacement of worn-out rubber seals unnecessary.

The rotary joint features a broad speed range of up to 600 to 3000 min-1 (rpm) depending on size; a very low turning torque of 0.003 to 0.2 Nm or less, making it an energy efficient unit; and can operate in temperatures ranging from -10 to 80°C.

For versatility the joints come in five sizes with an allowable radial load ranging from 1 to 50 N. Depending on size, the units can operate in pressures of -100 kPa to 1 MPa with 1, 2, 4, 8 or 12 circuits.
