NE-CD Pneumatic Clutch

NE-CD Pneumatic Clutch

The NE/CD pneumatic clutch is a compact unit with pneumatic clutch and release by spring reaction. The drive air chamber is supplied radially with compressed air at a nominal pressure of 5.5 bar. The air chamber is static and air consumption is minimal.

The most common assembly is to mount pinions or pulleys on the toothed clutch disc, which incorporates two ball bearings that make it self-supporting and very robust. There is also the design to join two coaxial shafts.



The NE/CD pneumatic clutch is a very compact toothed pneumatic clutch. It transmits torque when air pressure is applied and disengages when pressure is removed thanks to springs that release the toothed clutch discs. The drive air chamber is supplied radially with compressed air at a nominal pressure of 5.5 bar.

Being a toothed clutch, it can transmit more torque than an the NE/CD pneumatic clutch of the same size and also, depending on the toothing arrangement, the clutch can maintain synchronism between the driving and driven parts. The one entry per turn (360º) design is the most common.

  • Clutching must be done at rest or at low speed.
  • The disengagement is carried out at any speed.

It can also be supplied as clutch-brake, with friction brake by spring reaction. In this case, it is important to keep in mind that the driver is the clutch toothed disc and the driven one that will be braked is the clutch hub.
