45mm Round Galvanised Lazy Axle

45mm round galvanised lazy or unbraked axle is used on tandem trailers and has a maximum weight rating of 1450kg.

Australian MadeWhen used on a single axle, the rating is 750kg due to having no brakes.

Parallel axles are perfect for launching trailers in a hardstand boatyard or as the rear axle in a 2000kg tandem axle set.

Why use a parallel axle in a tandem set?

If your rig runs 15″ or 16″ wheels, the parallel rear axle will require less maintenance than a slimline axle suited to the larger bearing setup.

Parallel setups are suitable for 15″ and 16″ wheels only. Smaller wheels use the 1450kg slimline setups.

The Galvanised Unbraked Axle kit comprises:

Unbraked axles include axle nuts and split pins. All shafts are made and galvanised in Australia.

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.

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.
