Important areas of application

Hydrostatic construction drives, mainly in the medium and low power range, e.g.

Excavators, vibratory rollers, loaders, cranes, dumpers, forklifts, concrete mixers, concrete pumps, road finish- ers, rail vehicles, agricultural machines, tractors and small compressors.

Salient Features and advantages

  • Compact, light, robust, safe in operation, long service life.

  • Oil resistant and suitable for temperatures of -40° to +150°C (-40° to +300°F).

  • High torsional stiffness - allowing operation below critical speed without resonances.

  • Service-free combination of steel with highly shock resist- ant, temperature stabilized special Polyamid.

  • Short mounting length, easy assembly since it can be plugged in axially.

  • The hubs can be equiped with the proven, patented CENTALOC® clamping. With this the coupling hub can be fitted to splined shafts absolutely free of movement to eliminate fretting.

  • The hubs can be modified in form and length as needed.

  • Various series for standardized SAE-flywheels and non standard flywheels.

  • Low priced and available from stock.

    Design and Materials

    Modern design to give rational and economic manufacture, good material properties, design principle proven over the years.

    Sizes 100 and 125:
    One piece boss and dogs made from

    sintered steel.

    Sizes 110, 150 and 200: High quality precision radial dogs of alloyed sintered steel are fastened to the steel hub which is machined all over (tensile strength 600 Nm/mm2). The mounting of these dogs is done in our works with precise fixtures and with controlled tightening torques (TA = 90 Nm). Hubs with dogs are called “hubstars”. This should be seen as one unit and not be dismantled. The lateral flanks of the dogs are slightly crowned, to avoid edge pressure at angular misalignments.

    As option the hubstars for the sizes 100 and 125 are also available (eg for extra long hubs) made up from steel boss with bolted on dogs, as the large sizes.
