HDC good performance pneumatic industrial air clutch

Handong is an outstanding maker of pneumatic clutch in Shanghai, China. This HDC clutch is also called NAC industrial air clutch, it is one of our skilled and regular products. Pneumatic clutches HDC-02, HDC-04, HDC-06, HDC-08, HDC-10  refer to our air shaft clutch NAC-2, NAC-5, NAC-10, NAC-20, NAC-40, NAC-60.                                                                                  

The NAC-60 pilot mounted clutch is a large torque clutch, it can transmit torque reached to 590N.m. This model of clutch can well replace Nexen XHW 811100 good thermal dissipation clutch. Its structure is the same with other models clutch, but its outside looks a little different with other clutches.

NAC pneumatic clutch is driven by air pressure, it transmit torque stable and high. Now in the packing and printing industry, many magnetic powder clutches are replaced by air clutch. Why? Magnetic powder clutch can be used, while it will produce spark and degaussing magnetic after long time usage, it is not safe and torque is not stable, so many users changed it to air driven clutch. On the other hand, this pneumatic clutch is more economic for usage.

NAC industrial air shaft clutch is a kind of friction pads clutch. It is composed of cylinder, piston, flange plate, two-cut friction pads. After flowing into air pressure, piston pushed flange plate compressed with friction pads, then clutch linked. This clutch is like a connector, it can transmit power from driving part to driven part directly.

When the flange plate connected with power through chain wheel, gear wheel, V-belt pulley, when the motor working, driving flange plate will be rotated together. But in this time, the driven shaft is not working. If needed to transmit power from driving flange plate to driven shaft, we should input air pressure, making flange plate touches with friction pad, power transmitted to the driven part, so the driven part will be rotating together.

There are some models of it, like NAC2, NAC5, NAC10, NAC20, NAC40, NAC60. They transmits power from 26N.m to 590N.m of different models. Following is the detail technical data of it for your reference:

In above tables, we can see this friction clutch is pilot mounted. Its bore diameter is 20-60mm for different models. As NAC clutch is friction type clutch, so it is suitable for high speed connecting and rotating, rotating speed is 1200r/min-1800r/min. For this NAC-60, its max rotating speed is 1200RPM,  friction pads allowable abrasion is 223.5cm³.

This air shaft clutch is widely used in rubber machine rollers, conveyor, elevator, handling machinery, food machinery, printing machinery, crusher, motor, tire and rubber machinery, packaging machinery, forming machinery, automatic machinery, wire machinery, sheet metal machinery, filling machinery, plywood machinery, medical machinery, stretching wire machinery, fiber machinery, metalworking machinery, pulverizing machinery, tire forming machinery, paper making machinery and etc.

In this usage case, NAC pneumatic clutch is mounted with shaft and chain. It is used in tire making machine for power transmition. It is like a connector, delivery the motor power to load end, so the motor is doesn't need to start and stop frequency. With this connector clutch, it can prolong clutch's service life greatly.
