The Isothermos or Athermos axlebox is described in considerable detail. To ensure continuous hydrodynamic lubrication a forged steel flinger arm is bolted to the end of the journal, and when rotating this lifts up the oil contained in the bottom part of the cast-steel body of the axlebox and pours it on to the top of the bearing. An adjustable substantial bottom bearing keeps, prevents, or restricts movement of the axle inside the box. Increased steadiness of the axlebox is obtained owing to the limited movement of the axle. The current Athermos axlebox incorporates a cast or forged steel front cover held in position by an embedding groove, tightened by bolts against this groove in which a flat synthetic rubber joint is fitted. The sealing device for the inner face of the box is designed on the principle of a deflector ring. After proofing the box against oil leakage, it is also necessary to prevent any infiltration of dust or water. Various materials and designs have been tried including the use of laminated pressed wood impregnated with synthetic resin or synthetic rubber compounds. A self-centring sealing gasket made of synthetic rubber compound has been designed for tipping and other wagons.
