The wheels consist of two forged half-wheels made of light alloy.
They are attached together with bolts made of high-tensile steel and self-locking nuts.
An O-ring seal is put between the two half-wheels.
The wheels are equipped with:
  • taper roller bearings with protective seals,
  • drive keys for the brake rotor disks,
  • six fuse plugs which deflate the tire in the event of excessive brake overheat and thus protect against tire burst because of excessive pressure,
  • one standard inflating valve which you can replace by a valve with an incorporated pressure indicator (PSI type),
  • a provision for installation of a transducer for the Tire Pressure Indicating System (optional system).
Each wheel is installed on the axle with an axle sleeve.
Characteristics:
  • weight: 60.6 kg max.
  • melting point of the fuse plug:
    . first set, inside keys: 300 deg.C (572.00 deg.F),
    . second set, on wheel web: 183 deg.C (361.40 deg.F).

An O-ring seal is put between the two half-wheels.
The wheels are equipped with:
  • taper roller bearings with protective seals,

  • three fuse plugs which deflate the tire in the event of excessive brake overheat and thus protect against tire burst because of excessive pressure,
  • one standard inflating valve which you can replace by a valve with an incorporated pressure indicator (PSI type),
  • one overpressure relief valve,
  • a provision for installation of a transducer for the Tire Pressure Indicating System (optional system).
Each wheel is installed on the axle with an axle sleeve which the manufacturer supplies.
Characteristics:
  • weight: 87 kg max.
  • melting point of the fuse plug: 183 deg.C (361.40 deg.F).
These wheels can be equipped with tires of following dimensions:
  • 46X17 R20 for radial tires
  • 46X16-20, 49X17-20, 49X19-20 for bias tires.

    But as the BSCU and the aircraft pin programming depend on the tire dimension (stopping distance, anti skid tuning), you must install the tire corresponding to the aircraft configuration (pin programming, MLG door podger,...).
    The tire mixability configurations which are authorized are shown in the AMM Task 32-41-00-910-001.
It is possible to use either 1270 X 455 - R22 radial tires or 49 X 18 - 22 conventional tires on these wheels.
