The Timken AS5578 is a needle roller bearing thrust washer, designed to manage axial loads in tight radial spaces where a standard thrust bearing would not fit. Timken engineers thrust washers to work alongside needle roller assemblies, controlling end-play and handling thrust forces without adding significant stack height. Part number AS5578 is sold individually. Pro Gear and Transmission carries genuine Timken bearings for heavy-duty drivetrain and undercar applications.
