Operators looking to protect shaft seals in hydraulic systems now have another option in Zero-Max Overhung Load Adaptors, which provide an extra layer of protection to hydraulic actuated functions helping to ensure trouble-free operation. They provide an intermediate mounting platform between a motor and pump to absorb both internal and external stress conditions in a hydraulic system.
Hydraulic system seal protection is ensured when an intermediate connection and mounting platform called an Overhung Load Adaptor (OHLA™) is positioned between the motor and pump in a hydraulic system.
EXTRA PROTECTION WHERE IT IS NEEDED
Designed to provide an extra layer of protection to hydraulic actuated functions, Overhung Load Adaptors prevent shaft seal breakdown, a condition often unseen until system damage occurs. Replacing damaged shaft seals is laborious and costly because multiple hydraulic components usually must be disconnected to get at the seal failure. Now, these conditions can be eliminated using Overhung Load Adaptors for protection.
Designed for either face or foot mounting, standard Overhung Load Adaptors are available in over fifty models with input bore sizes that range from 5/8 inch to 3-1/2 inch (15.88 to 88.9 millimeters). SAE mounts available include A, B, C, D, E, and F mounts with 2 or 4 bolt mounting flanges. Overhung Load Adaptors are available with many shaft variations including splined, threaded, tapered and extended output shafts, all now available with the special Zero-Max corrosion protection process. Special input bores and housing modifications are also available.

CORROSION PROTECTION
The corrosion protection shaft option is another addition to over 1300 custom designs offered by Zero-Max to meet new and unusual overhung load system requirements. These specials include custom inverted bearing designs and multiple lubrication ports that increase the Overhung Load Adaptor’s load capacity, bearing life and smooth system performance. Manufactured to ISO 9001:2008 quality standards, Zero-Max Overhung Load Adaptors are ruggedly built with shafts precision machined from high quality 130,000 PSI Stress-proof steel. All custom Overhung Load Adaptor designs include a detailed CAD approval drawing submitted prior to manufacture.
VARIED APPLICATIONS
Overhung Load Adaptors are used in workboats, recycling systems, forestry shredders, cold planers for road paving, industrial conveyor drives and many others where hydraulic systems require shaft seal protection.
