39mm Round Galvanised Lazy Axle
39mm round galvanised lazy or unbraked axle has a maximum capacity of 750kg. Axles over 750kg require brakes.
Tandem axles under 2,000kg require brakes on one axle. Tandem trailers over 2t require electric brakes on all axles. In the case of braking requirements for boat trailers over 2t, elecrtrically activated hydraulic brakes are acceptable.
Axles and hubs are Australian made by Couplemate and Galvanised in Brisbane; as a result, you are purchasing the best equipment money can buy.

Calculating The Correct Axle Measurements
As a result of viewing the video above, calculate the face to face measurement.
- Measure the offset wheel. The wheel offset is the distance between the inside of the hub and the outside of the rubber.
- Add 50 mm to the offset. Alternatively, choose your own distance between the rubber and the chassis.
- Multiply by 2 for both sides. Add your chassis width to the above number.
Metric to Imperial ConverterConvert Imperial (inches) to metric (mm)
Still unsure of what measurements to take? Check out this handy guide below:
[P] – Check material specifications. What size and profile is the axle (for example, 45mm Square)
[T] – Overall axle length (tip to tip)
[F] – Hub face to hub face measurement
[A] – Chassis width
[C] – Tyre clearance
[B] – Back offset
[H] – Tyre to chassis
[G] – Axle pad centres
Identifying Bearing Combinations
You will also need to identify your bearing combination which can be done by pulling off a hub and bearings, and locating the number laser engraved onto the bearing. You will require both the inner and the outer bearing number.
