OHLA™ Overhung Load Adaptors By Zero-Max Provide Motor Bearing Support In Rugged Forestry Shredders
Plymouth, Minnesota: Forestry shredders used to reduce trees and shrubs to mulch employ Zero-Max OHLA™ Overhung Load Adaptors in their rotor power trains. Located between the hydraulic motor and cutters, the OHLA's provide load support to prevent bearing wear to the motor.

OHLA™ Overhung Load Adaptors. |
OHLA™ and OHLA hydraulic motor drives the cutting rotor through a pulley and timing belt system. |
Fitted with 50 sharpened cutters, the 28 inch diameter rotor is driven by a fixed displacement hydraulic motor through a timing belt and pulley drive arrangement with speeds up to 3000 rpm. The OHLA™ hydraulic motor package is powered by a variable displacement hydrostatic hydraulic pump, which is driven off of the vehicles main engine system.
In this system the OHLA™ relieves, absorbs and redistributes stress loads, thereby preventing bearing failure, excessive wear of internal motor parts and motor failure.
The OHLA model used in the forestry shredder system is a Model 900 Series with a SAE C mount. OHLA™ models also are available with SAE A, B, C, D, E and F mounts with 2 or 4 bolt mounting flanges. Models with splined, threaded, double-male and special shafts and other combinations are offered with short lead times. Standard models are available from stock.
