A non-standard rubber metal dust seal structure?

Oil seals can be used as dustproof sealing elements, but in severe dust sites or to protect other seals, special dustproof seals are more common. Then do you know what materials are used to make dustproof seals for different hydraulic equipment (different mechanical equipment) and different applications? Or do you know what type or section you use? Next, let's talk about what the dustproof sealing ring of different materials is.

First, the general hydraulic equipment dust sealing ring is made of rubber;

Second, the general air pressure mechanical dust seal adopts square or trapezoidal specification structure;

3. In order to prevent freezing from affecting the dust seal ring, the hydraulic cylinder working in cold areas is made of metal materials;

Fourth, the general chemical industry in order to prevent the movement of hydraulic cylinders adhering to other things should use metal dust sealing materials.

Square or trapezoidal sealing ring (dust ring) in the sealing principle is generally used rotary seal, dust sealing ability is closely related to the contact level, the tighter the contact, the better the dust resistance, but the greater the friction resistance.

If the use of pure rubber and rubber combined with the dust-proof sealing ring material is inhibited, it has a certain elasticity under the hardness requirements, and has good wear resistance and weathering resistance.
