39mm Round Unbraked Axle Assembly

39mm round unbraked lazy axle assembly is ideal for small trailers and boat trailers up to 750kg capacity. Boat trailer 39mm axle buyers may like to call us for galvanised equipment.

Australian MadeIf you require a 39mm round galvanised axle, please click this link.

We manufacture our axles from Australian steel and hot-dip galvanise them in Brisbane. We then machine the finished galvanised product.

39mm round assemblies are supplied with Japanese bearings and hubs, ensuring the best quality. It consists of the following:

  • 1 x 39mm round axle
  • Two lazy hubs
  • 2 x Japanese Bearings

It’s ideal for small trailers with a weight of up to 750 kg and comes greased and wholly assembled for your convenience.

39mm Round Axle Assembly, however, is not suitable over 2100mm or tandem trailers. In the case of a wide trailer axle assembly, the axle tends to suffer from axle flex. This wears out the springs rapidly as a result of reverberation of vibration starting from the centre of the axle to the spring. The springs wear out much more than they should.

Some of the models, this is suitable for our Ford, HT Holden, Commodore, HQ Holden, and Landcruiser 6-stud.

Calculating The Correct Axle Measurements

As a result of viewing the video above, calculate the face to face measurement.
  1. Measure the offset wheel. The wheel offset is the distance between the inside of the hub and the outside of the rubber.
  2. Add 50 mm to the offset. Alternatively, choose your own distance between the rubber and the chassis.
  3. Multiply by 2 for both sides. Add your chassis width to the above number.

Metric to Imperial Converter

Convert 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

How To Measure An Axle

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 numbers.

Where to identify bearing number. Look for the laser engraved number on the bearing.
