Zero-Max Offers a New Gas Nitriding Option to Protect Overhung Load Adaptors

It’s another first for Zero-Max—a unique Gas Nitriding option to protect Overhung Load Adaptor (OHLA) shafts while enhancing overall system performance.

Because OHLAs are most often used in harsh outdoor environments including exposure to heat, rain, humidity, salt water, dirt and debris, protecting the OHLA shaft can be an important consideration.  The new Gas Nitriding (Gaseous Nitrocarburizing) option for OHLA shafts provides superior corrosion resistance, surface hardness to boost strength and durability, and adds lubricity to the shaft, which benefits shaft seal life by reducing friction and wear.

Based on many decades of experience, OHLA applications that will benefit from Gas Nitriding protection to overcome challenging operating conditions include:
    • Oil exploration fracking systems
    • Marine deck winches, capstans and bow thrusters
    • Forestry equipment including mulchers, chippers and log loaders
    • Agricultural tractors, planting, harvesting and manure injection equipment
    • Electrification for outdoor mobile equipment including E-PTO applications… and more

All OHLA models feature robust ductile cast iron precision machined housings, high quality deep groove ball, taper, or spherical bearings, enhanced sealing technology, strong shafts delivering long operating life, a permanent precision machined face- or foot-mounting surface, heavy load capacities, and high-speed ratings. All models also feature precision gaskets or O-rings for sealing the mounting surface between a hydraulic motor or pump and the OHLA housing. 

OHLAs are available in SAE A through SAE F mount, Non-SAE mounts, double male shaft units, through-bore units, and are customizable for unique application requirements, with over 75 percent of OHLAs sold as special/custom designs to address specific application requirements.
