Trailer Axle Weight Rating for 2 Inch Square Axle


Hi, I have a triple axle trailer with 1.5 in spindle diameter with a 2x2 square tube between spindles, is there any way to verify what weight rating the axles are? Thank you


Expert Reply:

The 2x2 inch square axle is likely 3,500 lbs or less capacity. I would need more spindle dimensions or bearing numbers to assist. If you pull a hub and measure at the spindle where the bearings and seal ride using the digital caliper like # PTW80157 I may be able to give you a more specific capacity based on the spindle measurements.
