50mm Square Galvanised Lazy Axle
50mm square galvanised lazy or unbraked axle is used on tandem trailers and has a maximum weight rating of 1600kg in a parallel configuration.
Tandem axles under 2,000kg require brakes on one axle. Tandem trailers over 2t require electric brakes on all axles. In the case of braking requirements for boat trailers over 2t, electrically activated hydraulic brakes are acceptable.
The seal shoulder is an essential factor when selecting stub axles.
- Electric stub axles have a seal should set back 128mm for standard slimline bearings and 140mm for parallel bearings
- Marine stub axles have a rear shoulder 115mm to accommodate a marine seal
- Parallel Marine is 125mm to the rear shoulder
- 2t Electric is 180mm to the weld ring shoulder
- 2t Marine is 141mm to the back shoulder
Please measure the back shoulder before ordering.
Why should I use Dome Nuts?
I had a problem adjusting my bearings for the trip home from the Hawkesbury River.
No problem removing three wheels, however, the fourth wheel refused to move this wheel nut
No amount of leverage would unfreeze the rusty wheel nut.
The wheel nut protruded past the nut and has become rusted.
One of the guests in the caravan park produced a Hilti rattle gun. To my surprise, the rattle gun removed the rusty wheel nut immediately.

Trailer Axle Alignment
Installing a new axle is tricky for most installers.
Measure the distance from the chassis rail to the back of the hub on both sides. Once correctly aligned, install the u-bolts over the axle.
Alternatively, measure the chassis width of the trailer. This measurement allows us to weld the axle pads onto the axle before delivery. As a result of the installed axle pads, the axle will auto-locate over the spring centre pins.
In seconds, the axle is perfectly aligned and ready for the u-bolt kit to be installed.
