750KG - 39mm Round Axle. Suits small box trailers.
Suit LM bearings.
Common problem: Too much weight will bend this axle causing excess axle flex. Springs to fatigue - fail prematurely under incorrect loading.
Quite a common problem with 39mm Round Solid Axles and Hollow Axles. If your axle is 39mm Round and bending, buy a 45mm round axle and update to 1.5t. It really is not very expensive.
