The 91620 Roller Spindle is a heavy-duty zinc-plated steel boat trailer roller pin designed for compatible 12" flat roller brackets. Measuring 358mm overall length with a stepped 22–24mm diameter, it provides a strong mounting shaft for larger keel and centre roller assemblies. Its corrosion-resistant zinc-plated finish makes it an excellent replacement for boat trailer spindles that have become bent, worn, grooved or heavily corroded.

Important Fitment Information

Before ordering, confirm the existing overall spindle length, shaft diameter, roller bore and bracket dimensions. The 91620 measures 358mm overall and is described as having a 22–24mm stepped diameter, with approximately 23mm nominal shaft diameter.

Signs the Roller Spindle Needs Replacing

Replace the spindle when it shows heavy corrosion, bending, deep roller wear grooves, excessive shaft wear, deformation or damaged retaining points. Also inspect the roller bore and bracket at the same time, as excessive clearance can indicate wear in multiple components.
