Note: Please advise your axle length (tip-to-tip or face-to-face)t, and axle profile after order—for example, 2t, 3t, parallel, slimline.

Calculating The Correct Axle Measurements

1. Measure the offset wheel. The wheel offset is the distance between the inside of the hub and the outside of the wheel.
2. Add 50mmrubber’soffsett. Alternatively, choose the 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-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 by pulling off a hub and bearings and locating the number laser-etched on the bearing. You will need both the inner and outer bearing numbers.

How to calculate total axle length

The Face to Face measurements to calculate the Tip to Tip measurements are as follows: –

• S/L “0” Electric Drum – 103mm
• S “L”150mm Lazy – 100mm
• “0” Disk Rotor  – 98mm
• PLL “0” Electric Drum – 122mm
• 2″ 2” Electric Drum – 172mm
• 2″ 05mm Lazy – 172mm

Solid Axles rarely cause problems.

The price of a 45 mm square parallel axle can vary widely. Non-Couplemate axles are manufactured in various places, including India, China, Malaysia, and Australia.

The only real problems come from imported steel, which causes steel fractures along the beam and consistent hardness.

Other Common Problems and Tips:

If your 45mm-square parallel-trailer caravan axle is not engineered correctly, you may experience excessive bearing wear.

1. Rough seal journals can cause grease to leak through the rear seal.
2. Some suppliers supply non-virgin or scrap steel and forge it into solid Square or round shapes for axle production. Always ask for Australian Steel.
3. Chinese bearings are the second most significant cause of axle failure.
4. If you plan to get onto a highway, use Japanese bearings.
5. Combining Japanese Bearings and a 50mm Square Axle will significantly reduce rig maintenance.
