Product Description

Designs take the press building challenge to new levels. We have spared no expense in designing and building the most well balanced press on the market.
Our unique "gears on center line" design places the gears directly over the plunger guides that deliver tonnage vertically to the slide.
While this double pitman design cost a bit more, it makes the drive is more balanced than that of other eccentric press builders.
You will also notice that our gears are cast and weight balanced to offset the stroke on the eccentric lobe.
We have taken proven designs from Japanese press builders and improved them in precision, strength and smooth running balance.
Our high speed pinion gear and intermediate gear provide counter rotating main gears.
This is also a design feature for smooth balanced running of the drive.
The drive in the crown runs in a self contained oil bath for well lubricated and silent press operation.
HOLP / Hydraulic Overload Pistons are built into the slide body below the plungers. The HOLP System is set at 110% of press capacity to protect the press.
