Air Tube Disc Clutches and Brakes Typical Applications Wichita High Torque Clutch provides fast acceleration and long life on metalforming punch presses. Wichita Low Inertia Brakes increase tension control for paper unwind stands. Typical Wichita clutch and brake mounting on a press Wichita Spring-Set Air Release Brakes insure accuracy and high performance for a metal shear.
Air Tube Disc Clutches and Brakes Application Factors Clutch sizes are affected by the following variables: 1. Machines that operate under smooth loads require smaller clutches. These machines are driven by either multi-cylinder high speed engines or electric motors with reduced starting current. 2. Drives that require high starting current motors will require clutches with sufficient torque to prevent excessive slipping while starting. 3.

Air Tube Disc Clutches and Brakes Low Inertia and Very Low Inertia Clutches and Brakes Selection Requirements Summary The selection of a Low Inertia Brake is based on: As calculated, the torque required to stop the load in 5 seconds is 14,547 lb.in. Wichita Low Inertia Brakes are rated at 100 PSI. This application has only 80 PSI available. 1. Torque required to stop a load. 2. Friction area necessary to absorb rotational energy. 3. Contact velocity of rotating discs.
