SAE A Mount Overhung Load Adaptors

Click image to enlarge
SAE A mount Overhung Load Adaptors (OHLA) are designed for SAE A-sized motor or pump interfaces and absorb external loads to prevent shaft, seal, or premature motor / pump failure.  Overhung Load Adaptors also prevent contamination of hydraulic fluid in harsh environments by sealing out dirt, grime and other contaminants and help prevent costly maintenance and equipment downtime. They provide a sturdy mounting surface, can support heavy axial and radial loads, and permit the removal of hydraulic motors without disturbing gears and other mechanical components.

SAE A Overhung Load Adaptors for Hydraulic Motor Applications

Zero-Max SAE A overhung load adaptors are available in 2-bolt mount and 4-bolt Magneto mount options and feature rugged cast iron housings.  The standard 200, 300, and 500 series units feature 130,000 PSI stress proof steel shafts while the 350 Extra-Duty series feature 8620 heat-treated shafts.  Each SAE A OHLA model is available in several standard shaft options, are available in custom configurations, and allow for either deep-grooved, tapered, or shperhical roller bearings.

How to Select an Overhung Load Adaptor That Meets Your Specifications

SAE A OHLA are compatible with motors and shafts that meet SAE A size standards for bolt pattern and pilot diameter. When selecting an overhung load adaptor, you also need to consider the speed requirements of your application and whether you require standard or heavy-duty bearings.  The required lifespan of the application is also critical.  Contact Zero-Max for assitance in OHLA selection.
