  • Low Torque Rotary Joint MQR Series
  • Low Torque Rotary Joint MQR Series

A rotary manifold in which the piping ports are aligned in a spiral pattern for easy piping.
[Features]
· Stable rotational torque that is not easily affected by supply pressure or temperature fluctuations.
· There is no change in the rotary torque due to spool sticking to the rotating surface, even after a long periods of non-operation.
· Low rotational torque: 0.003 to 0.50 N·m or less.
· Operating temperature: -10 to +80°C.
· Allowable rotational speed: 200 to 3,000 min-1 (rpm).
[Applications]
· For air supplies to rotational/rocking shafts on metal-seal type turntables, robot arms, etc.

Note 1: The temperature 80° includes temperature rises during rotation.
Note 2: The starting rotational torque does not change with the supply pressure or with non-use (remains within starting allowable rotational torque), but it does change with the rotational speed.
Note 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.
Note 4: Rubber/resin couplings are recommended due to their excellent absorption of off center misalignments, shocks and vibrations.
Note 5: min-1 is the number of rotations per minute.
