Overhung Load Adaptors
Overhung Load Adaptors (OHLA®) help prevent breakdowns and extend the lifespan of mobile hydraulic systems. OHLAs prevent costly damage and downtime by isolating external loads from hydraulic motors and pumps. Zero-Max OHLAs also seal out grease and grime to protect motor components and prevent hydraulic fluid contamination.
- Provides support for radial and axial loads, resulting in extended life of hydraulic motors and pumps
- Seals out dirt, grime, and other contaminants
- Prevents contamination of hydraulic fluid in harsh environments
- Provides solid, permanent mounting surface
-
Permits the removal of hydraulic motors for servicing without disturbing driven gears, pulleys, or sprockets
