60mm Round 2t - 3t Mechanical Disc Braked Axle

60mm round 2t mechanical brake setups are rated to a maximum of 2t on the road for single axles.

Offroad usage in rural or agricultural applications achieves a rating of up to 3t for a single axle. Note: 2t brake calipers are installed on 3t mechanical disc brake assemblies.

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.

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

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.
