Pneumatic Spring Applied Brakes 
The New PFS400 Industrial Machinery and Wind Energy Friendly. W.C. Branham brings pneumatic spring applied caliper disc brakes to the factory floor and all the way up to towering wind energy turbines. Now there are 3 series to choose from. Welcome the PFS400. The PFS400 has four times the braking holding torque of the PFS47 series and twice that of the PFS200 series. The new PFS400 series is just the latest product designed to meet the needs of our customers. How do they work? Active minimum air pressure of 85 psi releases the brake piston (pulls the brake piston away) from the brake disc rotor and stores that energy in a Belleville disc spring stack (100 psi release rated for PFS400). Then, at loss of that air pressure the energy stored in the disc spring stack is emitted driving the brake piston and engaging the disc rotor for positive stopping.  Specifications(click |
