45mm round axle galvanised is rated at 1450kg on slimline bearings and 1600kg on parallel bearings and suited to single axle boat trailers

Heavy loads on light axles create what we call axle flex. Axle flex results in vibration at high speeds. This vibration occurs in the middle of the axle.

The result of axle flex is premature aging of the trailer spring and trailer vibration at high speeds.

When should I replace my galvanised axle?

Replace your 45mm round galvanised axle with a 45mm Square Axle if it is bending in the middle by more than 10mm. Place a straight edge along your existing axle to measure axle fatigue.

Round trailer axles up to 1800mm in slimline or parallel configurations are ideal for trailer weights up to 1450kg. The 45mm round axle may start to flex at full load over 1800mm long, causing axle fatigue.

Wider trailers require square axles for the best suspension performance.
