axle load capacity?

Hi all,i am building an off road camper and am now sourcing the axle.can anyone tell me the load cap of the axle as follows.45mm square,six stud cruiser hubs,ten inch electric brakes,ford bearings,31"x10-5" wheels on sunraysia type rims.aside to that i am running 7leaf 8mm tapering to6mm 1050mm eye to eye x 65mm wide springs.I am waiting on a quote for parallell bearings but would like some info to digest re suitability for my trailers o/all weight which should go about 750kg loaded.cheers danny

Hey Danny.
Ordinarily, a Slimline axle (45mm sq., Falcon bearings) is rated to 1400Kg with passenger car wheels and tyres, However, the extra unsprung weight of an Off-Road wheel and tyre will drop its rated capacity to 1300Kg. Similarly, a 50mm sq. Parallel axle is rated to 1600Kg on passenger car tyres, and 1500Kg Off-Road. The Parallel axle will jump a fair price as it runs a special brake drum, and for your application (750Kg), probably not required.

thanks yonnee,much appreciated,i can now let the heavy axle go and save a couple of hundred dollars as well.cheers,danny.
