Outboard Motor Loose Needle Rollers and Bearing Washers
MARATO supplies precision loose needle rollers and bearing washers for selected outboard motor gearbox, shaft and transmission repairs. These components are suitable for bearing positions where individual needle rollers run directly between a hardened shaft journal and a prepared housing bore.
Loose needle rollers provide radial load support while using very little installation space. Precision bearing washers and shims are used for positioning, spacing and controlling axial clearance in selected outboard motor assemblies.
Available Product Types
- Loose cylindrical needle rollers
- Precision-ground bearing rollers
- Flat bearing washers and spacing shims
- Individual sizes and mixed repair quantities
- Components matched by OE number or exact dimensions

Important Measurement Information
Loose needle rollers must have consistent diameter, length and surface finish. A small dimensional difference can affect bearing clearance and shaft operation. Measurements should be taken with suitable precision tools rather than estimated from engine horsepower alone.
Product Range Clarification
This page covers individual loose needle rollers and flat bearing washers. Complete K, KVE, KTE, KTUE and KS needle roller cage assemblies are listed separately. AXK thrust needle bearing kits and HK, F, TA, B and BH drawn-cup bearings also have separate product pages.
Wholesale and OEM Supply
MARATO supplies outboard motor bearing components to importers, wholesalers, marine repair workshops and aftermarket parts distributors. Mixed dimensions, samples, bulk quantities, customized packaging and OEM branding are available.
