Coupling and Cardan Shaft Applications

Application guidance for coupling and cardan-shaft inquiries in metallurgy, mining, cement, paper, power, chemical processing, wind power, petroleum and port machinery.

Use the application to define the drive duty

Coupling and cardan-shaft selection begins with the actual machine, load pattern, shaft arrangement and installation conditions. Application fields considered for this product range include the following industrial equipment contexts.

Metallurgy

Review shock load, reversing duty, roll-line geometry, surrounding heat and maintenance access.

Mining

Review starting torque, dust, impact loading, alignment and guarding requirements.

Cement

Review continuous duty, dust exposure, peak torque and access for inspection or lubrication.

Paper

Review continuous operating speed, alignment, production continuity and maintenance intervals.

Power

Review speed, torsional duty, shaft interfaces, reliability requirements and operating environment.

Chemical processing

Review corrosion, temperature, sealing environment and material requirements.

Wind power

Review variable load, reversing conditions, environmental exposure and service access.

Petroleum

Review hazardous-area requirements, corrosion, duty cycle and equipment interfaces.

Port machinery

Review outdoor exposure, shock load, reversing, braking and high-utilization duty.

Information required for preliminary review

  • Driving and driven equipment
  • Power, operating speed, nominal torque and peak torque
  • Starts, stops, reversing, shock load and braking conditions
  • Shaft diameters, bore forms, keyways and installed length
  • Radial, axial and angular displacement
  • Temperature, dust, humidity, corrosion and outdoor exposure

Application name is not enough

Two machines in the same industry may require different coupling structures. Use the application only as context; confirm the selected family and model from the actual operating and connection data.
