The M-121080 Roller Spindle is a heavy-duty zinc-plated steel boat trailer roller pin measuring 285mm overall length × 18mm diameter. Designed for compatible keel, centre and bow roller assemblies, it provides a strong mounting shaft with corrosion protection for marine trailer use.

Suitable Applications
- The M-121080 is suitable for compatible boat trailer keel roller assemblies, centre rollers, bow rollers, roller brackets and marine trailer roller systems requiring a 285mm × 18mm spindle.
Before ordering, confirm the existing overall spindle length, shaft diameter, roller bore and bracket width. The critical dimensions are
- 285mm overall length × 18mm diameter
- 11.22" overall length × approximately 23/32" diameter
- Do not select the replacement solely by roller width. Different bracket and eye-post arrangements can require different spindle lengths even when using the same diameter shaft.
Signs the Roller Spindle Needs Replacing
- Replace the spindle if it develops bending, heavy corrosion, deep wear grooves, shaft deformation, excessive wear or damaged retaining points. The roller bore and mounting bracket should also be inspected, as excessive clearance can indicate wear in more than one component.
