Refuse collection vehicles operate 8 hours a day, 365 days a year. The articulating packing mechanisms at the rear of these vehicles are designed to withstand dusty, dirty, heavily loaded, low-speed cyclical operating conditions.
To make the process cleaner and more efficient, the manufacturer wanted to replace the mechanisms’ greased brass/bronze bushings and pins that would fail prematurely if not continually regreased.
HSG (High Strength GAR-MAX®) heavy-duty bearings were tested for their ability to withstand the magnitude of the loads involved in the application. With a static load capacity of 415 MPa, the self-lubricating, maintenance-free bearings were more than capable of handling the extreme loading conditions.
In addition, these industrial bearings provide excellent shock load resistance, low friction performance and high wear resistance under slow oscillating movements or rotating speeds.
The results of field trials indicated a considerably longer service life with HSG heavy-duty bearings.
