2t Hydraulic Disc Braked Axle

The 2t hydraulic disc braked axle kit utilises a 50mm square galvanised to form the basis of the boat trailer setup.

The 50mm square hydraulic braked axle kit is a robust choice, and when you use it in tandem, extend the rating 4.5t.

Important: Axle pads locate and centre the axle of the trailer springs. Please advise the outside chassis width of your trailer. We are then able to weld axle pads into the correct position. This service is not included in the price as some customers do not require this service.

The axle kit consists of the following:

Galvanised axle kits have almost zero chance of rusting.

Calculating the face-to-face measurement on your axle is important to know whether this would be the right fit. Here’s how you can do it:

  1. Measure the whole wheel offset, that distance between the inside of the hub inside the rim and outside of the rubber
  2. Measure the distance between the chassis and rubber or add 25 mm
  3. Add the chassis width by multiplying the number by 2

Technical Specifications

  • Weight –  120 kg.
  • Dimensions – 200 x 30 x 30 cm.

Calculating The Correct Axle Measurements

  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.

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.
