Axle specific questions should be directed to the axle manufacturer. LOAD RATINGS The load/capacity rating of a given axle is determined by the axle housing strength, bearing capacity, and hub capacity. For some ultra- lightweight axles, the reduced axle housing thickness may be the weak link, but usually it is the bearings or hub that will be the limiting factor. These axles and components are typically designed under the assumption that the action line of the tire load is located between the two bearings. This is typically found with dual tire mounting or with single tires with very low outset wheels with the axle rating being similarly determined. If wheels with greater outset are used, the resulting cantilever loading may require lower ratings for some of the axle components. The level of de-rating and the implications thereof are determined by the axle manufacturer, so they should be consulted prior to fitment of outset single wheels. Prior to contacting the axle manufacturer, you should consult the axle identification tag to obtain the following information: – Axle Manufacturer –Manufacturer’s Model # – Axle Serial Number – Axle Capacity Information on actual operational axle loading (as opposed to rated load) is crucial, since the axle manufacturer may recommend de-rating the axle below the vehicle manufacturer’s GAWR (Gross Axle Weight Rating). With this data in hand, contact the particular axle manufacturer at the numbers listed below for specific application information.
