1000KG - 40mm Round Axle. Suits box and some tandem 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 40mm Square Solid Axles and Hollow Axles. If your axle is 40mm Square and bending, buy a 45mm round or square axle and update to 1.5t. It really is not very expensive.
