The maximum capacity of 50mm Square axles is 3t. Bearing sizes determine the axle capacity. Note: It is recommended for heavier loads on farm trailers.

The 50mm square unbraked axle assembly is your solution to axle flex from smaller axles. Axle Flex will rapidly wear your springs due to the vibration reverberating from the centre of the axle back to the spring.

Effectively, your spring is working twice as hard as it should.

Calculating The Correct Axle Measurements

How to 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 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-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.
