Overhung Load Adaptors

Overhung load adapters are hydraulic system components that protect shaft seals and prevent breakdown by absorbing internal and external stress from the motor and pump. They also seal out grease and grime to protect motor components and prevent contamination of hydraulic fluid. SAE overhung load adaptors prevent costly damage to shaft seals and are used for fan drives, recycling equipment, mixer units, industrial conveyor drives, and various other hydraulic motor applications.
