45mm Square Parallel Axle
45mm square parallel axles are manufactured in China and other places, and it is unusual to find Australian-made goods.
We believe the Couplemate medium tensile axles are amongst the best on the market and an excellent investment.
Importantly, our axle profiles are tested on each axle; however, there is no procedure for testing imported axle balls for composition or profile accuracy.
45mm square parallel axle is perfect for your trailer, caravan or camper if you want a robust rig for remote or off-road locations.
When measuring from the face of the axle, add 117mm to this measurement to get the length from the tip of the thread to the tip of the thread.
The parallel axle helps you tow your rig straight and true, perfect if not, then below are a few tips.
45mm Square Parallel Axle Tips
One known problem is jack-knifing Bobcat trailers while reversing, which places excess pressure on the inner rear tandem tyre. Avoid sharp turns when reversing.
Parallel bearings are also known as Ford bearings. LM bearings are known as Holden or standard bearings.
These problems occur because some manufacturers rate their 45mm Square parallel axle near 1800kg per axle. While this rating is OK under normal conditions, it fails under reversing conditions.
If sharp turns are unavoidable when reversing, upgrade to 2 t axle kits, and these problems disappear. If your Square axle is bending, buy a 50mm square axle and update to 2t. It is not very expensive compared to replacing springs that have suffered fatigue.

Other Common Parallel Axle Problems and Tips:
Poorly engineered axles cause massive problems, and you may experience some of the following issues:
- Poorly machined or rough seal journals can cause a loss of grease through the rear seal ID.
- Examing 45mm square parallel axles before installation for cracks in the steel along the axle.
- Some suppliers supply non-virgin or scrap steel and forge this steel into a solid square or round shape for axle production. Always ask for Australian Steel.
- Chinese bearings are the second most significant cause of axle failure.
- If you plan to get onto a highway, use Japanese bearings.
- Combining Japanese Bearings and a 45mm square parallel Axle will help lower your rig’s maintenance costs.
- Are your tandem tyres wearing unevenly?

Solutions:
Upgrade from 45mm Square axle to a 2t axle kit. We rarely have problems with these larger kits. A Couplemate assembled axle with Japanese gives you our unconditional guarantee of a well-made, well-backed axle assembly.
Calculating The Correct Axle Measurements
- Measure the offset wheel. The wheel offset is the distance between the hub’s inside and the rubber’s outside.
- Add 50 mm to the offset. Alternatively, choose the distance between the rubber and the chassis.
- 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 Identify Bearing Combinations
You will also need to identify your bearing combination, pull off a hub, and locate the number laser engraved onto the bearing. You will require both the inner and the outer bearing numbers.
