45mm Round Axle Galvanised
45mm round axle galvanised is rated at 1450kg on slimline bearings and 1600kg on parallel bearings and suited to tandem boat trailers
Measure your axle length from tip to tip. Axles supplied with nut, washer and split pin.
Parallel Bearing Sizes
2 x 68149 – 59.10 OD, 35.00 ID – Large Inner Bearing
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 from axle flex is premature ageing of trailer spring and trailer vibration at high speeds.
Replace your 45mm Round Axle Galvanised with a 45mm Square Axle if it is bending in the middle by more than 5mm.
Round 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 over 1800mm causing axle fatigue.
Wider trailers require square axles for best suspension performance.
