40mm Square Stub Axle
40mm square stub axle LM or otherwise known as a standard profile.
The axle length is measured from tip to tip.
The stub axle is supplied with a nut, washer, and split pin.
Welding a 40mm Square Stub into a 50mm tube with 5mm walls makes a good farm trailer.
Select from an electric or marine turn. An electric turn suits both electric and hydraulic backing plates, while a marine turn suits marine or unbraked axles.
Hollow Axles
Hollow axles are rated the same as solid solids up to 1600kg.
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 4 sides. Mark the 50mm tube 25mm back from the end of the stub when inserted.
- 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.
