Axle Capacity of 1-1/2 Inch Square Axle.
Updated 07/28/2015 | Published 07/27/2015 >
Question:
Hi- I was wondering if you could help me determine what my axles are rated for. They are an old axle and they are 1.5inch square tubing. I cant find a marking any where. The inside hub bearing is a timken m12649. Any help would be appreciated. Thank you

The only way to know for sure the capacity of your axle is based on the information from the manufacturer when the axle is new. Typically, 1-1/2 inch square axels have a capacity somewhere between 1,000 - 2,000 pounds. Sometimes the spindle and hub can also help point us in the direction of finding axle capacity, but even then it is still an approximation since it is impossible to tell if they are the same size as what came on the axle.
The bearing number your provided does not match any of our axles or hubs, and it is not a typical size for a trailer bearing. This makes it more difficult for us to determine the actual capacity of your trailer axle.
Buying a new axle is the only way to be sure of your axle's capacity. I have also attached a link to our trailer axles. If you would like to let me know the hub face measurement, the spring center measurement, the wheel bolt pattern, and brake type, I will be happy to make an axle recommendation for you.
I have attached a diagram of where to measure to find the hub face and spring center measurements for you.
