Custom Overhung Load Adaptors

Custom overhung load adaptors, also known as specials, prevent contamination of hydraulic fluid and eliminate premature motor or pump failure due to overhung loads. Another benefit of OHLAs is that they seal out dirt and grime and permit the removal of hydraulic motors for servicing without disrupting other critical components. Overhung load adaptors are designed with 2-bolt or 4-bolt mounts that meet SAE sizing specifications and are used for various hydraulic applications including forestry, agriculture and road construction.
