Hydraulic motors and pumps with outward-extending shafts can be connected to various driven components, such as pulleys and gears. Overhung loads created by these connections can exert significant radial and axial forces on the hydraulic unit’s shaft and bearings. Overhung load adapters (OHLAs) provide support for these shafts, reducing the load on the internal bearings […]

When fluid power and power transmission products are discontinued, finding replacements can be challenging. Zero-Max now fills this Overhung Load Adaptor void with its new 212k and 412k OHLA models for 2-bolt SAE A mount and 4-bolt non-SAE mount applications requiring a 1-1/4 in. output shaft. For both new and replacement applications, these new OHLA […]

Zero-Max is now offering three entirely new Extra-Duty Overhung Load Adaptor (OHLA) models. Based on decades of experience solving overhung load issues in the most demanding applications, the new designs feature a number of carefully chosen upgrades including spherical bearings, enhanced sealing technology, stronger shafts and a longer profile delivering increased operating life, heavy load […]

Described as the first “Plug & Play” shaft locking bushing, the ETP-HYLOC from Zero-Max is a hydro-mechanical design featuring hydraulic quick connectors for mounting. This new design feature makes it faster and easier to install the ETP-HYLOC as compared to purely mechanical designs that have many fasteners requiring a high tightening torque, often being mounted…

The all new Zero-Max model 650 overhung load adaptor features heavier duty bearings, stronger shafts and longer profile. Designed to provide more radial and axial load support for hydraulic motors and pumps, this new model 650 meets the more robust requirements of today’s motor applications. This new SAE B model 650 is in the middle […]

Zero-Max Overhung Load Adaptors protect shaft seals in hydraulic systems. They provide an intermediate mounting platform between a motor and pump to absorb both internal and external stress conditions in a hydraulic system. Designed to provide an extra layer of protection to hydraulic actuated functions, Overhung Load Adaptors prevent shaft seal breakdown, a condition often…

Hydraulic motors and pumps are used in outdoor environments that are often dusty and dirty. These environments can be damaging to shaft seals simply because grit will work its way in between the shaft and sealing area. Once started, this begins to abrade the elastomer, altering the shaft surface finish in the sealing area. Seal…
