utility trailer axle capacity

admin

Not a welding question but I'm trying to determine the capacity of a used single axle trailer. The axle has numbers stenciled on it 629598 T3569 64139 and I haven't found any reference to these. Don't know the manufacturer.Other data: hub face spacing 69", spring centers 54", spring length 25.5", shaft OD 2 3/8, primary frame angle iron 3" x 2" @ 3/16" thk, bed size just under 5' x 10'.Thanks in advance for any help.
Reply:You said thanks for any help.I have a 2000 pound rated trailer and the bore of the outer wheel bearing is one and one sixteenth inch, a tapered roller bearing.  You should see brake stuff for anything over 3000 pounds.  Good chance 2990  is it but some of that would go on the tongue not the wheels.  Does it have tires? read the rating of the tires add together and subtract some perhaps 25% or so see what that is.fran
Reply:a good trailer supply house can i.d. your bearings and determine an approx. weight rating, along with spring width, thickness, and pack numbers.Lincoln SA 200Esab Caddy 160Thermal Arc 201TSMiller Dialarc HFI don't like making plans for the day because then the word "premeditated" gets thrown around the courtroom....
Reply:2 3/8" OD is typically 3500 lbs. but that is dependent on the thickness of the wall. taking the bearings in to a local parts store should be able to tell you too. another tell is the number of lugs on the wheels. based on the size of the trailer, spring length, and OD of the tube, I'd guess the axle is rated for 3500. but if it doesn't have brakes the trailer may only be rated for 2990.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger

Reply:There is more to trailer capacity than just the axle.   If someone puts a 3000# axle on a light frame, that doesn't make it a safe 3000# trailer.   Axles are probably fairly standard but the design and structural frame depends on the manufacturer.Ken
