OHMA

The OHMA Piercing cylinder operates using an "air over oil " intensification principle to produce non-shock force. This method of operation allows the cylinder to remain compact and provides numerous advantages to metalworking applications:

  • Low impact (non shock) advance to the work to minimize tool skidding, breakage and wear as well as part deformation
  • Fully controllable force output to match specific applications
  • Compact construction to minimize air consumption and allow the cylinder to be positioned in confined work spaces
  • Automatic compensation for variable part positions
  • Simple construction and operation for ease of use and minimal maintenance

The standard OHMA Piercing cylinder is supplied in the following range of styles/specifications:

Bore Size 2" to 8"

*Ratio

79:1 to 1700:1 (thirteen standard ratios are available)

Stroke

1-1/2" to 8"

Mounting

a variety of mounting styles are available
Rod Style male and female threaded, straight, custom


*The ratio is the force multiplication factor that is used to determine the force generated by the cylinder. For example, a 156:1 ratio OHMA piercing cylinder produces forces equal to 156 times the incoming air pressure. This means that operating the cylinder using 55 psi will produce (55 x 156) 8580 lbs. of force. Operating the same cylinder at 70 psi will produce (70 x 156) 10920 lbs. of force.

CenterLine now has a product configurator for its OHMA® Piercing Cylinders. This program takes the user through the selection process, from force calculation to the selection of a fluid reservoir.
