Zero Max :: Overhung Load Adaptors

Overhung Load Adaptors (OHLA)

Reduce Large Motor/Pump Stresses in Heavy Duty Vehicle Drive Trains with Overhung Load Adapters

ZERO-MAX Is A World-Leading Expert In Overhung Load Technology. We designed the first complete line of SAE "A" through SAE "F" mount OHLA overhung load adaptors. Today, we provide immediate shipment of standard models from stock.

From the smallest Model 200 SAE "A" mount to the largest Model 1500 SAE "F" mount, OHLA's feature rugged housings of 25,000 PSI tensile cast iron, shafts of 130,000 PSI stress-proof steel, ball or tapered-roller bearings, many different shaft options and attractively painted housings. All models may be either face or foot-mounted.

Benefits

  • 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.
  • Provides a solid, permanent mounting surface

The OHLA Product Line

Model 200 SAE "A" Mount
Applications utilizing SAE"A" 2-bolt mount with ball bearings for motor or pump shafts up to 1 inch in diameter.

Model 300 SAE "A" Mount
SAE "A" 2-bolt mount with same mounting dimensions as Model 200, but utilizes larger ball bearings which allow for heavier overhung loads and a larger input bore diameter (up to 1.25").

Model 400 4-bolt mounting (non-SAE)
Accommodates same loads as the Model 200 with ball bearings for motor and pump shafts up to 1 inch in diameter.

Model 500 SAE "A" Mount
SAE "A" 4-bolt mount, which uses tapered-roller bearings. Standard input bores include: 1-1/4" keyed, 1"-6B spline, or 14 tooth 12/24 spline.

Model 600 SAE "B" Mount
SAE "B" 2- or 4-bolt mount using tapered-roller bearings. Standard input bores include: 7/8", 1", or 1-1/4" keyed; 13 tooth 16/32 spline, or 15 tooth 16/32 spline. Also available with 1" keyed through-bore as a standard.

Model 800 SAE "C" Mount
SAE "C" 2- or 4-bolt mount using tapered-roller bearings. Standard input bores include: 7/8",1", or 1-1/4" keyed; 14 tooth 12/24 spline. Also available with 1" keyed through-bore as a standard.

Model 900 SAE "C-C" Mount
SAE "C" 2- or 4-bolt mount with same mounting dimensions as the Model 800, but using larger tapered-roller bearings which allow for heavier overhung loads and a larger input bore diameter. Standard input bores include: 1-1/2", or 1-3/4" keyed; 14 tooth 12/24 spline, or 17 tooth 12/24 spline.

Model 1000 SAE "D" Mount
SAE "D" mount using large ball bearings for heavy-duty applications. Standard input bores include: 1-3/4" keyed, or 13 tooth 8/16 spline.

Model 1250 SAE "E" Mount & Model 1500 SAE "F" Mount
Both the SAE "E" and SAE "F" mounts have the same physical size; only the pilot diameter and bolt circle are different for motor or pump mounting. These models use large spherical-roller bearings for heavy-duty applications. Input bores are made to customer specifications up to a 2-1/2" diameter. Custom Models Modified dimensions and special features are available.
