Overview Tschan shaft couplings

Tschan elastomer shaft couplings

The Tschan elastomer shaft coupling reduces torque shocks and compensates angular, radial and axial shaft misalignments. Also available with flange, hub, brake drum, brake disc, etc.

  • Tschan-B elastomer claw coupling

    Puncture proof steel claw coupling with radially arranged buffers for high torque levels and high revolutions. Buffers can be easily changed when installed, using radial extension.

    - Compensates angular, radial and axial shaft misalignments.
    - Radial mounted elastomeric buffers (VKR or Pb82), replaceable without axial disassembly of the coupling.
    - Reduces torque shocks.
    - 12 sizes of 240 up to 900 mm.
    - Torque of 2,500 up to 55,000 Nm
    - Bores up to 400 mm.
    - Various options:

    • Reinforced hub (BHHD)
    • Brake drum (BS)
    • Combinations of the above mentioned options
