A new device aims to overcome the problems of tube twisting encountered during rotary movements on chip mounters or industrial robots.

A new device aims to overcome the problems of tube twisting encountered during rotary movements on chip mounters or industrial robots The new series MQR metal-seal rotary joint has a low rotating torque of one-tenth to one-hundredth that of conventional rubber seal types, and is available with a wide range of rotation performance, from slow and smooth to high speed rotation (3000rev/min)

There is very little valve abrasion within the unit, and this ensures a long life - estimated to be in the region of one hundred million to one billion rotations.

In addition, the use of a metal seal prevents the seal from sticking to the rotating surface, even after a long period of inactivity.

And the rotating torque is resistant to temperature change, from -10 to +80C.

Other specifications include: minimum operating pressure of -100kPa; maximum operating pressure of 10bar; a weight of 0.016 to 1.26kg (depending on model selected); and a port size of M5 x 0.8.
