How to Order a Replacement Axle Beam
Answers to the following questions will provide all of the necessary information to get your axle beam ordered and in your hands quickly. Make sure you have the answers to these questions close at hand when placing your order.
Tubular Axle Beams

  1. Spindles - Are they straight, drop, or E2 lube?
  2. Inner and Outer bearings - What are the bearing numbers?
  3. Seal - What is the I.D. and O.D. or part number of the seal?
  4. Tube - What is the outside diameter?
  5. Spring Pads - What is the measurement from centre to centre of the pads?
  6. Hub Face - What is the measurement from the outside face of hub to outside face of other hub? or
  7. Brake Flange - What is the measurement from outside to outside of brake flanges?
Equation to Figure Hub Face From Flange to Flange Dimension
This chart is a handy guide for figuring the hub face dimensions, when you only have a bare beam with a flange from which to measure.

Note:
These equations are valid for any axle the same hub is used. That is to say, for example, any hub that goes on a 3,500 lb axle has a total flange to hub face difference of 6.34" regardless of whether it is a straight, drop, or torflex.
Torflex Axle Beams

  1. Spindles - Are they standard or E2 lube?
  2. Inner and Outer bearings - What are the bearing numbers?
  3. Seal - What is the I.D. and O.D. or part number of the seal?
  4. Beam and Suspension - What is the weight capacity of the axle?
  5. Mounting Brackets - What is the outside frame measurement of the trailer?
  6. Hub Face - What is the measurement from the outside face of hub to outside face of other hub? or
  7. Brake Flange - What is the measurement from outside to outside of brake flanges?
