Outboard Motor Thrust Needle Roller Bearings and Washers
MARATO supplies thrust needle roller bearings and matching steel washers for selected outboard motor gearbox, drive-shaft and transmission applications. Their flat axial design provides load support while requiring limited installation space.
A typical assembly consists of one AXK needle roller and cage unit positioned between two hardened steel thrust washers. The bearing supports axial loads, while the washers provide suitable running surfaces for the needle rollers.
Available Bearing Configurations
- AXK thrust needle roller and cage assembly
- AXK bearing supplied with two steel thrust washers
- Steel-cage and selected composite-cage configurations
- Individual bearings or complete bearing-and-washer kits
- Replacement bearings matched by OE number and dimensions
