The Bedford 22500 axle was fitted to the KGTE site-tipper, which was powered by the 381 cu in version of the 466 engine:-

It would have had hydraulic brakes of course but it only operated at 12 tonnes (or slightly less).
The TK KH (13/14.5 tonne) model also had hydraulic brakes and would have had either a Bedford 22500 single-speed axle or an Eaton two-speed - but it would also have 10-stud wheel-hubs!

The KG and KH artics probably had Eaton two-speed axles (and would maybe operate up to 24 tonnes).
