50mm Square Overlay Axle Parallel

A 50mm square overlay axle parallel is made in Australia to your specifications.

This axle type is manufactured from solid medium tensile steel, but the stub axles are welded on top of the main structural beam.

The centre of gravity, therefore, lowers the trailer height by an amount equal to the distance from the centre of the beam to the centre of the stub axle.

After ordering, we require the following information because we like it right the first time

  1. Wheel Backspace
  2. Outside to Outside Chassis width
  3. Pick-up is recommended; however, we can use your transport or give you a price for our carrier.

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 hub’s inside and the rubber’s outside.
  2. Add 50 mm to the offset. Alternatively, choose your 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 number.

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

All our 45mm Square Overlay Axle PLLs are built identically with zero variation in camber.

Weld rings are essential to unbolt and reassemble your existing 10″ electric brake setup.

50mm Square overlays are almost standard on car trailers, horse floats and boat trailers. If you need a lower centre of gravity, a drop or overlay axle may be ideal.

Parallel axles are ideal for that extra capacity that you need from time to time.
