PRODUCT ADVANTAGE

The temperature 80°C includes temperature rise during rotation.

The start-up torque does not change with the supply pressure or with non-use (remains within the maximum start-up rotation torque), but it does change with the rotation number. (Refer to page 450).

A rotary joint refers to a pipe connecting device, and the connected pipe can rotate relative

Can be used to transfer gas, liquid, oil and other media

Compact design structure, flange connection, effective integration into customer equipment

1) The temperature 80°C includes temperature rise during rotation.
2) The start-up torque does not change with the supply pressure or with non-use (remains within the maximum start-up rotation torque), but it does change with the rotation number. (Refer to page 450).
3) If using at a speed above 600 min-1 (r.p.m.), ensure rotation is in the direction in which the joint is fastened.
4) Rubber / resin couplings are recommended due to their excellent absorption of off center, shocks, and vibrations.

Low Torque Rotary Joint NMQR

Our pneumatic products have been widely used in all walks of life.

Applications

In order to satisfy customers' tighter requirements to pneumatic components, we also cooperate with RWTH Aachen University to develop full range of NNT pneumatic control components with most sophisticated technology and technics.

We have the most advanced production equipment and testing equipment in industry ,because we always attach great importance to the pneumatic product quality.

In addition, strict management and control are always carried out in each step of quality management in order to ensure every ex-factory product of NNT can meet the highest quality standards.
