The MW-4309 Galvanised Roller Spindle is a compact boat trailer roller pin measuring 132mm overall length × 16mm diameter. Designed for compatible bow, keel and centre roller assemblies, the galvanised steel construction provides strength and corrosion protection for marine trailer use. Its 16mm shaft suits rollers with the appropriate bore clearance, making it an ideal replacement for worn, bent, grooved or heavily corroded boat trailer roller spindles.

Suitable Applications
- Suitable applications include boat trailer roller brackets, bow roller assemblies, keel rollers, centre rollers and other marine trailer roller systems requiring a 16mm spindle with approximately 132mm overall length.
Before ordering, measure the existing overall spindle length, shaft diameter, roller bore and inside bracket width. For this MW-4309, the critical dimensions are
- 132mm overall length × 16mm diameter
- 5.20" overall length × approximately 5/8" diameter
- Do not select a spindle based solely on the roller's nominal size, as different brackets can use different spindle lengths.
Signs the Roller Spindle Needs Replacing
- Replace the spindle if you find bending, corrosion, deep wear grooves, shaft deformation, damaged retaining points or excessive wear where the roller rotates. Check the roller bore at the same time, as a badly worn roller can quickly damage a new spindle.
