Shaft Couplings for Reliable Power Transmission Without Interruptions

Reliability Where It Rotates – Industrial Shaft Couplings

Every industrial drive system requires one key component – one that compensates for misalignments, absorbs vibrations, connects the driving and driven shafts, and transmits torque without damage. These are shaft couplings – essential mechanical elements for reliable torque transmission in all types of drive systems.

Our offering includes a wide range of couplings and shaft connections suited for various operating conditions – from light-duty automation tasks to heavy-duty industrial loads. Available in materials such as plastic, aluminum, cast iron, or steel, they adapt to the demands and operating conditions of your system.

Functions of Shaft Couplings

Couplings and shaft connections serve multiple functions, the key ones being:

• Transmission of torque between two shafts
• Absorption of dynamic shocks and vibrations
• Compensation of axial, radial, and angular misalignments
• Protection of the drive system from mechanical damage
• Compact connection between different shaft types

They ensure stable and safe drive operation – even in the presence of mechanical irregularities like inaccurate alignment, angular displacement, or axial offset.

Overview of Shaft Coupling Types

Jaw Couplings

Composed of two jaw elements with an intermediate rubber insert. Suitable for medium-duty systems where minor shock absorption is needed.

• Excellent vibration damping
• Easy to install
• Allow slight axial and radial misalignments

Elastic Couplings

Use elastic rubber or plastic inserts to transmit torque while damping mechanical loads.

• Ideal for applications with frequent starts
• Compensate for axial, radial, and angular deviations
• Act as shock absorbers and protect the motor

Chain Couplings

Designed with a chain and two sprockets, providing a robust solution for heavy-duty industry.

• Capable of high power transmission
• Easy maintenance (just remove the chain)
• Excellent shock resistance

Clamp Shaft Couplings

Operate backlash-free and ensure rigid yet precise power transmission.

• Easy adjustment without a key
• Ideal for servo drives
• Compact design

Rubber Shaft Couplings

Made from highly elastic rubber materials, these couplings offer quiet and secure shaft connections.

• Quiet, maintenance-free operation
• Dampen high-frequency vibrations
• For low-demand or automated applications

Gear Shaft Couplings

With radial gear teeth, they allow for highly precise angular and axial misalignment compensation.

• High torsional stiffness
• Angular displacement compensation up to 2°
• Used in CNC, robotics, and machinery construction

Universal Joints (Cardan Shafts)

Designed to transmit power at significant angular displacements.

• Compensate angular misalignments up to 30°
• Available in telescopic versions
• Ideal for machines with dynamic axis displacements

Elastic vs. Rigid Couplings – What to Choose?

• Elastic Couplings: Absorb shocks, dampen vibrations, and tolerate greater misalignments (perfect for fluctuating or unstable loads).
• Rigid Couplings: Best where exact, direct power transmission without torsional losses is needed (e.g. positioning systems, servo motors).

Also available:

• Compensating couplings with axial movement
• Toothed couplings for combined axial and radial compensation
• Universal joints for extreme angular offsets
