Master Power Transmission (MPT) provides enclosed parallel and right angle gearboxes for use in many industrial applications including material handling, food processing, and mixing applications. MPT’s APG is designed and manufactured in the U.S. for applications requiring efficiency and power density without sacrificing quality and robust performance.

The Master APG is a proven and effective design for the industrial world. Using FEA (Finite Element Analysis) the housing is designed to be compact while maintaining housing rigidity to ensure shafts, gears, and bearings are not exposed to excessive flexure and extraneous loads during operation. Bearing spans for the MPT APG are kept to a minimum to avoid shaft deflection and excessive loads and all Master APG gearboxes are designed with bearings that will provide a B10 life of at least 5,000 hours.  

The spring loaded lip seals in all APG gearboxes are specially formulated for low drag, reduced heat generation and long life. Each APG unit is factory filled with a long life synthetic lubricant having a wide temperature operating range well in excess of 200°F at full load and is USDA H2 approved for most food processing and handling applications.

Gear tooth angles in the helical gearing of the APG are optimized to minimize bearing size, maximize gear load sharing and provide quiet operation. All MPT APG gears and pinions are case carburized and ground for a AGMA Class 9 precision finish. The result is a gear with a very hard outer shell (minimum Rockwell 58Rc) for suitable wear resistance and a ductile inner core that provides the gear or pinion with the toughness required to withstand shocks and vibration.    

Many gearboxes use heavy press fits on all mating internal components making component disassembly and replacement very difficult. Additionally, housings are often cast as one or two pieces making it very difficult to access internal components. MPT has taken a different approach with APG keeping disassembly in mind including pry slots on housing covers. Features such as this make it easy to access the internal components to change seals, bearings and gears whenever necessary.
