SMC Pneumatic's new MQR rotary joint is now available to local manufacturers. Based on results seen overseas, the company predicts that in Australia the product will simplify the manufacture, operation and maintenance of machines using rotary action.
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. Unlike similar products on the market, the new MQR's dynamic metal seal prevents sticking and makes the replacement of worn-out rubber seals unnecessary.
SMC claims the metal construction has led to a life span of up to one billion rotations under its life test conditions.
The new rotary joint features a broad speed range of up to 600 to 3000rpm depending on size; a very low turning torque of 0.003 to 0.2Nm or less, making it an energy efficient unit; and can operate in temperatures ranging from -10°C to 80°C.
For versatility the new products come in five sizes with an allowable radial load ranging from 1N to 50N. Depending on size, the units can operate in pressures of -100kPa to 1MPa with 1, 2, 4, 8 or 12 circuits.
