Double Male OHLAs

By Mike Brezonick02 May 2019

Zero-Max announced that it overhung load adaptors are now available in double-male shaft models. The new units incorporate a compact, self-contained design that provides a common mounting surface incorporating an input and output shaft. Alignment of both shafts is assured by design, the company said, and it can provide a one-piece solution replacing multiple components often used to make twin shaft connections.

A sealed cast iron housing is used to prevent contamination and internally, the OLHAs utilize 130,000 psi rated steel shafts with ball, tapered roller or spherical bearings available.

Applications include jackshaft designs where the driveline is supported by the OHLA with a small sprocket at one end and a large sprocket at the other end; pump and blower setups where a driver is coupled to one end of OHLA and an impeller or blower fan is mounted and supported at the other end; Power take-offs (PTO) where one OHLA shaft end connects to a female spline input on an engine, gearbox or transmission while the other end provides a male output shaft; and female through-bore setups where the OHLA shaft extends through the unit acting as a supporting pillow block bearing with the OHLA housing used to prevent contamination from the operating environment.
