Crank Shaft - Steel Fabricated

BROWN BOGGS offers a variety of Heavy-Duty press designs. Flywheel type presses are rated at full capacity 1/16" off bottom of stroke, while Single and Twin End Driven geared type presses have full rated capacity at " and " off bottom of stroke respectively. Straight Sided geared presses are available as either Single or Double Back Geared.

BROWN BOGGS Heavy Duty Straight Side presses range in capacity from 150 to 1000 Tons with bed sizes to 216" left to right at speeds up to 300 Strokes Per Minute.

Dual Processor Press Control

The BROWN BOGGS press control, with dual microprocessor, meets or exceeds ANSI B11.1, OSHA 1910.217 and CSA Z142 press control standards for control reliability. Standard features of dual processor press control include anti-repeat, anti-tie down, brake monitor and chain brake detection.

Four Piece Fabricated Steel Frame

BROWN BOGGS extra heavy bed and bolster design ensure minimum bed deflection of 0.0015" per foot (unless otherwise stated) thereby optimizing the structural integrity and capacity of the press. All components are precision machined and are fitted, keyed and fastened to provide an extremely rigid assembly. This provides excellent noise and vibration dampening characteristics.

8 Point Adjustable Gibbing and Slideways

Eight point gibbing maintains parallelism during the full stroke even with off centre loading and the long slideways of precision hand fitted bronze wear plates provide exceptional stability and longer die life.

Hydraulic Nut and Tie Rod Design

The tie rods are manufactured from high carbon steel and are tightened to a definite preload by split hydraulic nuts designed to reduce production downtime in the event of a press jamming on bottom.

Adjustable Air Counterbalance

Pneumatic counterbalancing affords smoother, safer press performance and better clutch action at higher speeds and assists in off-setting the weight of the slide and dies.

Variable Speed Drive

A Direct Current variable speed drive, with regenerative mode for flywheel braking, is provided complete with current limiters. Heat sensors are installed in the drive to detect over temperature and shut down the press if necessary. Remote speed indicator and speed controls for desired speed range are housed in a freestanding moveable console.


Bridge, connecting bearings, replaceable wear strips, and removable lower saddle bushing are all made of high grade alloy bronze and hand scraped to ensure the highest degree of accuracy and maximum wear life. Backshaft and flywheel assemblies are fitted with anti-friction tapered roller bearings.

Automatic Lubrication

Fully automated Trabon recirculating oil lubrication is provided for all main and pitman bearings, gibs, and counter-balance cylinders. Oil flow monitoring blocks in conjunction with heat sensors in all bearings are monitored through the PLC to ensure safe press performance and will shut down the press in the event of a catastrophic reduction in oil flow or overheated bearings.

Combination Clutch/Brake

The combination clutch/brake unit has an air actuated clutch and spring actuated brake, mechanically connected to prevent overlap on pickup or dropout. For geared presses, backshafts are split to provide quick disassembly of unit for maintenance purposes.
