Overhung Load Adaptors for Mobile Hydraulic Motors

Click image to enlarge

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. They also seal out grease and grime to protect motor components and prevent hydraulic fluid contamination. Zero-Max OHLAs are field-proven for use on belt/chain drives, fan drives, recycling equipment, mixer units, industrial conveyor drives, and various other hydraulic motor applications in the toughest environments.

  • 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
