How a Teddy axle is built
Six steps from a length of steel to a production-ready axle your line can bolt on without touching it.
Grade 50 steel
Beams start as ASTM A572 Grade 50 steel. The grade is the number that matters: 50,000 psi minimum yield strength.
Cut to your numbers
Hub face and spring centers come off your drawing, or outside-of-bracket width on a torsion axle. Nothing is forced to a stock length.
Spindles on
Machined spindles go on each end. Their bearing and seal journals are held to tight tolerances, because that is what keeps a hub running true.
Seats, flanges, brackets
Spring seats, brake flanges and torsion brackets are welded on in position, so the axle drops onto your frame the same way every time.
Wheel ends built
Seals, bearings, hubs, drums and brakes are assembled and set. You get a complete axle, ready to install.
Proven, then shipped
Axles are fatigue tested to one million cycles and built under IATF 16949 and ISO 9001 certified systems. They ship wrapped, capped and quality-checked.
