39mm Round Stub Axle, Castellated Nut, washer and split pin
39mm round stub axle is used on small trailers and as spare wheel carriers on boat trailers. We understand how to make a lousy axle and know what makes an axle great. Poorly turned axles cause bearing failure.
The axle rating is 375kg each or 750kg per pair.
Hollow Axles
Hollow axles are rated the same as solid solids up to 750kg. American imported trailers have hollow axles.
How to install a stub into a hollow tube
- Cut the tube to length, including the stub measurement.
- Drill a hole no smaller than 12mm on all four sides. When inserted, mark the 45mm tube 25mm back from the end of the stub.
- Insert the stub weld into place.
- Weld the stub holes to secure the end of the stub into the tube.
- Finally, the hollow axle stub must protrude past the springs and u-bolts once affixed into position.
Standard Bearing Sizes are
| Inner LM Bearing Sizes | ID 31.75mm | OD 59.10mm |
| Outer LM Bearing Sizes | ID 19.05mm | OD 45.20mm |
| LM Seal | ID 37.5mm | OD 59.10mm |
| Dust Cap | 45.20mm |
We recommend you use only Japanese Bearings.
A 50mm round tube with a 5 mm wall thickness retains the 750kg rating of a pair of 39mm round stubs.
Reduce axle flex with a shorter length axle or more oversized diameter axle.
If your camper, caravan, or trailer is around 2400mm in length, select a 45mm Square Axle with a rating around 1500 kg.
