TENNSMITH's power shears combine all the features of our foot shears with the advantage and convenience of air or hydraulic operation. TENNSMITH power shears are a productive addition to any shop. The air shears utilize heavy-duty, tie rod-type pneumatic cylinders, which provide up to 40 strokes per minute in capacity materials.

A foot-operated air valve control, pressure regulator, air gauge, oiler/condenser cups and neoprene, padded holddown feet are standard features. We recommend a maximum air supply of 75 psi for operating these shears at rated capacity. Where air supply pressures exceed 75 psi, an in-line regulator is helpful to provide pressure control. Generally, a 10-hp stand-alone compressor would be the minimum recommended size to operate these shears.








The model 52H cycles at 60 stokes a minute, thanks to its first class hydraulic system. The unit features a solenoid actuated valve, 3-hp electric motor, 10-gallon tank with sight gauge and thermometer, pressure gauge, check valve and industrial quality cylinders. The motor is protected by a magnetic starter. Other electrical safety features include a low voltage on/off switch; low voltage, shrouded, electric foot switch; step-down transformer with low voltage circuit fuse; fully enclosed electrical box; and insulated reinforced conduit for all wiring. Models 36A and 52A are ideal ways to enhance shearing productivity with minimal investment.

All shears are standard equipped with high-carbon high-chromium (HCHC) blades.
