World-Leading Expert In Overhung Load Technology.

PROVEN TECHNOLOGY - OHLA

ZERO-MAX – A World-Leading Expert In Overhung Load Technology.

Zero-Max has set the industry standard with the Overhung Load Adaptor (OHLA) design. The first complete line of SAE “A” through SAE “F” mount overhung load adaptors was designed by Zero-Max.

Overhung Load Adaptors (OHLA) are essential components in hydraulic systemswhere they Absorbs radial and axial loads to protect motors and pumps. They extend the lifetime of machines and reduce the risk of breakdowns by Minimise wear on shafts and bearings.

Zero-Max A/S offers a complete range of SAE Mounting Overhung Load Adaptorsthat are designed to fit various industrial applications. Our adaptors ensure:

✅ Efficient power transfer without unnecessary strain
✅ Reduced wear & longer lifespan for hydraulic systems
✅ Different mounting options - 2-bolt & 4-bolt designs
✅ Tapered roller bearings for increased load capacity
✅ Customisation options

FEATURES

OHLA®

  • Eliminates premature motor or pump failure due to overhung loads (axial and radial) on your motor or pump shaft
  • Prevents contamination of hydraulic fluid in harsh environments
  • Permits the removal of hydraulic motors for servicing without disturbing driven gears, pulleys or sprockets
  • Seals out dirt and grime
  • Removes radial loads from hydraulic motors and pumps – technology for mobile hydraulic systems including the agriculture, forestry, and road construction markets

OHLAs

Increase Motor Durability and Life.
