SAE A Mount Overhung Load Adaptors

Click image to enlarge
SAE A mount overhung load adaptors are designed for SAE A-sized motor interfaces and absorb stress to prevent premature pump shaft and motor failure.  Overhung load adaptors 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 mount options and feature rugged cast iron housings and 130,000 PSI stress proof steel shafts. Each SAE A OHLA model is available in several shaft options and feature either deep-grooved for standard applications or tapered roller bearings for heavy-duty applications.
