Pneumatic steel and copper based friction plates clutch 

BDC model pneumatic multiple friction plates clutch is made of some groups of steel and copper-based friction plates. As usually it is composed of five groups of friction plates, customized is also available. Just this material of friction plates, it can be used in wet working situation without slippage. And friction mode friction pads can be used to high speed connecting and rotating.

Group sheaves clutch can transmit high torque, it is driven by air pressure, released via return springs. Power motor controls driven part after clutch linked, when this clutch separated, driving part rotating with motor, then driven part stoppped. 

BDC multi-disc air clutch is composed of cylinder, piston, steel plate, copper based sheet, driving plate, driven plate and etc. After supplying air pressure, piston pushes driving plate to slide along the direction of the axis, group steel disc compressed group copper-based friction plates to come into an integrated structure, clutch linked. After exhausting air pressure, group steel discs and group copper-based friction plates are separated by separate springs, clutch released.

Air multiple friction plates clutch is also called multiple shaft clutch, multiple copper-based friction plates and steel disc engagement together by air pressure. No slippage, engagement tightly, integrated structure, easy installation, small size and large torque. Compared with tooth clutch, multiple air friction plate clutch is more suitable for high-speed integration and high-speed rotating.

There are some models of it: BDC-40, BDC-60, BDC-100, BDC-200, BDC-300. They can transmit torque from 400-3000N.m. Following is the detail technical data of this compressed clutch for your reference:

From above technical table shown, we can understand that this clutch can delivery high torque, max reached to 3000N.m. Steel and copper based friction material, make sure it can be used in hard working situation, such as engineering car, sanitation vehicle, water pump fan and etc.

On the other hand, bore dimension of this clutch is 30-95mm available. Its air volume capacity is large from 33.10 cm³ to 112.30cm³. Its connecting speed is fast, 700-2500rpm, nearly high connecting. And its rotating speed is also 700-2500r/min, so it can be used in high rotating working situation.
