HOW TO MEASURE YOUR TRAILER AXLE
WHEN REPLACING THE SAME LENGTH AXLE
When ordering a replacement trailer axle, we will need to know the overall length (tip to tip) or the hub face to hub face measurement.
It is important to ensure these measurements are correct as the slightest change in axle length can cause wheels to rub on your chassis or guards.
HOW TO MEASURE A TRAILER AXLE
FOR A NEW TRAILER BUILD
When ordering an axle for a new trailer build you will need to know several things:
What is the trailers chassis width
What wheels will I be using and what is their back space
What axle rating will I require
A:STUB MEASUREMENT – The measurement from the face of the hub to the tip of the axle. Each axle rating has a different stub measurement (see below).
B:WHEEL BACKSPACE – The measurement from the face of the hub to the rear tyre bulge (see below).
C:WHEEL GAP – The measurement of the space between the tyre bulge and the trailer chassis.
D:CHASSSIS – The measurement of the trailer chassis on the outer most points.
AXLE LENGTH = A B C D E F G
A & B TYPE AXLES 100mm (50mm EACH SIDE)
PARALLEL 114mm (57mm EACH SIDE)
2 TONNE 170mm (85mm EACH SIDE)
3 TONNE 184mm (92mm EACH SIDE)
WHEEL BACK SPACE
To measure your wheels backspace, place the wheel on the ground face up.
Then measure from the ground to where the wheel meets the hub face. (mm)
This is to ensure the wheel wont rub on the trailer chassis.
