NAC-40 40kgs torque pneumatic clutch Made in China

NAC air shaft friction clutch is a regular and standard industrial pneumatic clutch. It is widely applied in winding machine to transmit power, the torque is from 26N.m to 590N.m. By the way, this NAC HDC clutch is air shaft clutch, its bore diameter is 20-60mm, customized is also available.

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.

Following are the special characters of this pneumatic shaft clutch:

1. Torque adjustment range is wide 

It can be adjust torque in wide range according to air pressure adjustment.
2. Safe and reliable
It will not produce electric spark.

3. Suitable for high-frequent, continuous sliding movement
It is durable in high frequency, high load and continuous sliding movement industry situation, also can be used as limiter.
4. Small impact
After connecting, increase air pressure softly, to reach stable start and reduce impact for equipment
5.Long service life
Good heat dissipation and less abrasion.
6. Compact structure
Belt can be connected with clutch for working, convenient for usage.

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

As NAC clutch is a friction type clutch, so it is suitable for high speed connecting and rotating, max rotating speed can reached to 1800r/min. And its friction pads are made of non-asbetos material, it is wear-resisting, durable and safe. On the other hand, these pads are easy for replacement.

This pneumatic clutch is driven by air pressure, that is to say, when supplying air source, clutch will be linked to transmit power from motor part to driven load part via shaft; when exhausting air source, clutch will be separated. In this situation, clutch's driving part rotating with power in idle.

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.

Above picture shown is the NAC pneumatic clutch used in textile machine. It is shaft and belt installation, power transmitted through belt. As usually, this shaft and driving part rotating in idle, after supplying air pressure, clutch linked, power transmited from driving part to driven part directly.

In this case, NAC clutch is shaft and belt connection. Clutch's cylinder end and shaft are fixed on a frame via screws, driving part is connected with belt.
