Air Powered Toggle Press Units

The thin, compact pneumatically operated Toggle Press is an economical solution to apply force where you need it.

"THIN" Profile Toggle Press

BTM's patented "THIN" air powered toggle presses produce high forces using 80 psi (5.5 bars) air pressure! The "THIN" profile allows for close stacking. These extremely simple and rugged presses have only three moving parts. A unique, pivoting, rectangular piston drives the non-rotating ram through a force multiplying toggle linkage. This quick acting mechanism drastically reduces air consumption as compared with conventional pneumatic cylinders doing the same work. BTM press bodies are constructed of light weight aluminum hardcoated to a Rockwell C-70 for excellent wear characteristics.

General Information

The following sections contain general information about the product.


The BTM Air Toggle Press has an innovative toggle linkage which utilizes a unique rectangular vane piston as one of the levers used to multiply the force of incoming air pressure. The simple yet reliable mechanism allows the press to be thin and compact while multiplying force from 25 to 1000 times incoming air pressure. The mechanism produces high output forces from common shop air (80psi/5.5 bar).

An animation showing how BTM Air Toggle Presses work
  1. How a Toggle Press Works- Step 1Air Pressure at port "B" holds the piston and ram in the retracted position.
  2. How a Toggle Press Works- Step 2Air pressure at port "A" moves the integrated piston against the toggle linkage extending the ram.
  3. How a Toggle Press Works- Step 3Maximum force is reached as the linkage toggles to center.
  • Air Toggle Press units deliver high force from a small, lightweight and compact unit making them ideal for use with a robot or in automated lines.
  • Air Toggle Press units operate in any orientation with no special accommodation.
  • The thin design allows easy access to narrow work piece cross sections and the positioning of multiple presses on close centerlines.
  • Presses operate on and are rated at commonly available shop air (80 psi / 5.5 bar).
  • Press force is not linear but continues to increase as the ram extends.
  • Only low cost air delivery components (valve, hose, fittings, etc.) are required to cycle the press.
  • Special presses can be designed to accommodate your application.
BTM Toggle Presses stacked closely together. The thin profile allows for close stacking.
  • The enclosed internal parts are protected from external contamination.
  • Standard ram styles for easy mounting of tooling are available including the modifiable “S” model ram.
  • Optional proximity switches to signal ram extended and retracted are available.
  • Presses are equipped with lubrication fittings for greasing internal bearings.
  • In line air lubrication is not required.
  • Internal cushions are standard.

Application Information

The following sections are provided to help match an Air Toggle Press to your part. More detailed information is typically available in our Product Literature section.
If you are considering this product for your project, please view the contact information below.


Your assembly or fabricating process (piercing, clinching, riveting, coining, swedging, pressing, bending, shearing, or anything else) has a force requirement at each point of tool travel which describes a force requirement curve. Also, the ATP has a force output at each point of ram travel which describes its force delivery curve.

Correct sizing requires comparison of these force curves and the addition of a "safety factor" to achieve expected duty cycle even when conditions are not optimal - e.g. tooling gets dull, air pressure drops, work-piece tolerances change, etc.

Let BTM recommend the proper size press for your process using our experience with safety factor and library of force curves or we can measure the force curve for your specific process.

Contact our Application Department and let us size and quote a press for you.
