Load support For hydraulic motors


General DPN

Zero-Max overhung load adaptors (OHLA) provide load support to eliminate premature hydraulic motor or pump bearing failure. OHLA’s provide a solid mounting surface while sealing out dirt and contamination in harsh environments.

Zero-Max OHLA’s provide support for both radial and axial loads. Applications include forestry shredders, recycling systems, cold planers for road paving, industrial conveyor drives, and many others.

Manufactured to ISO 9001:2008 quality standards, Zero-Max OHLA’s are ruggedly built of premium materials. Housings are cast to Zero-Max specifications by our certified foundry. Shafts are precision machined from high quality 130,000 PSI stress-proofed steel.

Designed for either face or foot mounting, OHLA’s are available with many shaft options including splined, threaded, tapered and extended output shafts. Special input bores and housing modifications are also available.

Over 50 standard models are available for handling overhung loads (axial and radial) on most motor or pump shafts. Input bore sizes range from 5/8 inch to 3-1/2 inch. SAE mounts available include A, B, C, D, E, and F mounts with 2 or 4 bolt mounting flanges.
