40mm Square Galvanised Axle

40mm square galvanised axle max rating is 1000kg on Holden LM bearings and 1250kg on Composite bearings.

Measure your trailer axle from tip to tip. Axles supplied with nut, washer and split pin.

Causes of Axle Flex

1. Heavy loads on light axles create what we call axle flex.
2. Axle flex is a result of axle vibration at high speeds.
3. This vibration occurs in the middle of the axle.

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

If your 40mm Square Axle is bending in the middle by more than 5mm your axle needs replacing with 45mm Round or Square axle depending on the width of your trailer.

Wider trailers require square axles for best suspension performance.
