About Power Engineering and Manufacturing, LTD

Power Engineering and Manufacturing, Ltd. is a company that specializes in the custom design and manufacturing of HEAVY DUTY gear boxes. We presently have produced several hundred models for an even greater number of applications and those numbers continue to increase. Our gear boxes are operating throughout the U.S.A. and in more than forty-eight countries around the world. Our product has proven itself in many industries with a wide variety of challenges. Our advanced engineering enables us to reach the greatest power density in the industry and at the same time increase durability and efficiency. We can design and build a gear box that will match a machine's requirements without sacrificing any performance. When we overhaul a competitor's gear box our MEGAGEARS® enable us to triple the service life.

Power Engineering and Manufacturing, Ltd. was established in 1975 through a partnership between Saul Hersvovici and several members of the Warren family.  From 1975 to his passing in 2007, Saul Hersvovici was President and prime visionary of PEM. He steered this company with a pertinacious fervor and creativity that made us into what we are today. After Saul’s passing, the Warren family purchased full ownership and is now lead by John Warren, President, who is directing us toward a higher caliber of excellence.

Our current facility was specially designed and built in 1992 for our type of manufacturing. Subsequent additions have brought the current physical size to over 110,000 square feet. Our design department is staffed with mechanical engineers, design engineers, and CAD technicians. 100% of our machining operations are completed by CNC machines with the latest software that is linked to our engineering department. We pride ourselves on retaining machinists that are highly skilled and are continuously trained on the latest techniques.

First Choice - PEM

At PEM, our philosophy is 100% commitment to superior product performance. Our units are designed and built to exceed AGMA standards while incorporating the design parameters needed by the customer. Our gearing constantly proves the reliability of the MEGAGEAR® design by increasing fatigue life and increasing horsepower and torque capability. MTBF is exponentially increased when compared to standard gearing. Our units are designed to exceed shock loads that other mfg's can only dream to achieve.

Expert Design Engineers and Expert Application Engineers

Our engineers design units to come within .01% of output RPM. Each Geared unit goes through a FEA to achieve our goal for each unit to have up to a 600% shock load capacity and a minimum of a 2.5 Service Factor. We have been designing custom gear boxes for over 35 years and are well versed in adverse applications. From helicopter test stands to roll crushers, in any environment imaginable, our units will work for you.

Why is PEM the workhorse of the Industry?

Quality Gearing MEGAGEAR® Technology - Wear longer under adverse conditions Generate less heat and run more quietly Higher fatigue life (250%) Heavy Duty Bearings Taper roller bearings are used throughout to increase load capability and lengthen service life Stronger Housings Additional reinforcing and greater wall thickness of PEM's tough housings, whether cast or fabricated, contribute to PEM's high performance ratings Advance Technology Designed to far surpass ISO and AGMA standards, manufacturing is done on CNC machines with highly skilled operators Rugged Shafts Made of heat treated 4140 for increased shock loads Pinions Case hardened 8620 with integral ground gearing Gears Heavy duty splined gears-NOT KEYED
