Overhung Load Adaptors

Overhung Load Adaptors Zero-Max is a world-leading expert in Overhung Load Technology The first complete line of SAE “A” through SAE “F” mount OHLA Overhung Load Adaptors was designed by ZERO-MAX. We set the industry standard with the OHLA design. 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, OHLAs feature rugged housings of cast iron, shafts of 130,000 PSI stress proof steel, ball, tapered, or spherical roller bearings, many different shaft options and attractively painted housings. All models...
