So where does this steel come from?

Newcastle in New South Wales continues its rolling bar mill that pulls its feedstock from Whyalla in South Australia.

The other major arm of the Newcastle steel industry is Commonwealth Steel at Waratah, NSW. This wire works mill pulls its steel from 1000 car bodies per day.

Australian Steel is a fascinating story. Such a pity the Television media reporting on Australian success stories is not better supported.

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

Other Common Problems and Tips:

If your 50mm square parallel trailer, caravan axle is not properly engineered you may experience excessive bearing wear.

  1. Rough seal journals can cause a loss of grease through the rear seal.
  2. Some suppliers supply non-virgin steel or scrap steel and forge this steel into solid square or round shape for axle production. Always ask for Australian Steel.
  3. Chinese bearings are the second biggest cause of axle failure.
  4. If you plan to get onto a highway, use Japanese bearings.
  5. The combination of Japanese Bearings and 50mm Square Axle will help you greatly with lower maintenance for your rig.
