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.

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.Model 200 SAE A Mount Overhung Load Adaptors
