30mm width key type friction ring

key type  differential air shaft:

1. The low tension slip shaft is based on the principle of air compression, so that the device is inflated inside the shaft to cause the expansion of the top block, and the two air intakes drive each torque machine

The group expands outwards and sets each torque according to the amount of inflation pressure, which is suitable for PE elastic film materials.

2. According to customer needs, professional evaluation and design and manufacture, production of special specifications and special tension, special surface treatment.
3. All kinds of special environment (dust-free, corrosive, high temperature environment) can be applied.Key type Air differential shaft(friction rings)3”outer diameter:φ75 Expand diameter:φ78mm
