CENTA Couplings and Original Replacement Elements

Explore original CENTA couplings, flexible elements and replacement components for demanding power transmission systems. AWELASTIC supplies genuine CENTA products for marine, industrial, power-generation, construction, agricultural and mobile equipment applications.

Our CENTA product range includes CENTAFLEX, CENTAMAX and CENTAX coupling families in multiple sizes, designs, elastomer materials and Shore hardness options. Products should always be selected according to the exact coupling series, size, type and drivetrain specification.

Original CENTA Couplings and Replacement Elements

CENTA develops flexible coupling and power transmission solutions designed to transfer torque while helping control torsional vibration, absorb shock loads and protect connected drivetrain components.

Different CENTA coupling families are developed for different operating conditions. Some designs prioritise high torsional flexibility and vibration damping, while others provide compact installation, higher torsional stiffness, axial movement compensation or compatibility with engine flywheels and hydraulic pumps.

For this reason, a replacement coupling should not be selected only by its appearance or approximate dimensions. The complete product marking and technical specification must be checked before ordering.

CENTA Coupling Product Families

CENTAFLEX A Couplings

CENTAFLEX A couplings are highly flexible elastomeric couplings used in a wide variety of diesel-engine, generator, pump, compressor, marine and industrial drive systems.

The elastic element helps damp torsional vibration and shock loads while compensating for axial, radial and angular displacement. CENTAFLEX A elements are available in multiple sizes, mounting types and Shore hardness specifications.

Common versions include Type 0 and Type 0-S. Although these variants may appear similar, their mounting arrangement and installation requirements differ. Always confirm the complete type designation shown on the existing coupling.

CENTAFLEX H Couplings

CENTAFLEX H couplings are commonly used in diesel-hydraulic drive systems. Their robust elastomer elements incorporate metal bushes and are designed for reliable torque transmission in demanding mobile and industrial machinery.

These couplings are frequently installed between diesel engines and hydraulic pumps in excavators, construction equipment and other heavy machinery. Identification should be based on the coupling size, number and arrangement of bushes, dimensions and equipment specification.

CENTAFLEX K Couplings

CENTAFLEX K couplings provide a compact connection for diesel-driven hydraulic systems and other space-restricted applications.

The coupling normally consists of an engineered polymer element combined with matching inserts or hubs. Different versions may have similar external shapes but different bore dimensions, spline profiles, bolt patterns or torque capacities.

CENTAFLEX K products are used in construction, agricultural and mobile machinery from a wide range of equipment manufacturers.

CENTAFLEX X Couplings

CENTAFLEX X couplings combine low weight and low rotational inertia with reliable power transmission. They are used in drives where compact dimensions, higher permissible speeds and efficient torque transfer are important.

The correct CENTAFLEX X replacement must be matched according to the complete product code, coupling size, hub execution and installed machine configuration.

CENTAX V Couplings

CENTAX V coupling elements are designed for demanding mobile, marine, railway and industrial drive applications.

Their flexible elements help isolate torsional vibration and shock loads while allowing reliable torque transmission between connected drivetrain components. CENTAX V elements are available in different sizes and must be selected according to the original coupling specification.

CENTAMAX Couplings

CENTAMAX couplings are torsionally flexible coupling systems widely used in marine propulsion, generator sets, railway equipment and heavy industrial machinery.

The CENTAMAX product family includes multiple sizes, elastomer compounds, Shore hardness options and connection designs. Depending on the coupling size and application, available fitment types may include SB, SBE, SC and SCE executions.

These type designations are important because they describe different fastening and mounting concepts. A coupling with plain holes may not be interchangeable with a version using threaded holes, even when the nominal size is the same.

CENTAMAX G Couplings

CENTAMAX G couplings are designed particularly for generator and genset drive systems where torsional vibration control is essential.

Different sizes and Shore hardness specifications provide different torsional characteristics. The original Shore value should always be maintained unless an alternative has been approved through the relevant drivetrain calculation or technical documentation.

CENTA Couplings for Different Applications

CENTA coupling products are used in a broad range of power transmission systems, including:

• Marine propulsion and auxiliary drives
• Diesel and gas generator sets
• Industrial pumps and compressors
• Hydraulic pump drive systems
• Construction and earthmoving machinery
• Agricultural and forestry equipment
• Railway and mobile equipment
• Industrial power units and test systems

The application alone is not sufficient to identify a replacement. The same equipment range may have been manufactured with different engines, pumps, flywheel housings or coupling versions.

How to Identify the Correct CENTA Coupling

Before ordering a CENTA coupling element, inspect the existing component and record all available information.

Please provide:

• The complete CENTA series and size marking
• The full product or part number
• The coupling type or fitment designation
• The elastomer material and Shore hardness
• The engine, gearbox, pump or generator model
• The machine manufacturer and model
• External and internal dimensions
• The number and arrangement of holes, bushes or inserts
• Clear photographs of both sides of the coupling
• Photographs of the complete installed coupling assembly

Markings such as patent numbers may appear on an original element but may not identify its size, type or Shore hardness. Always check all available markings instead of relying on a single number.

Why Shore Hardness and Coupling Type Matter

The Shore hardness of a flexible coupling element affects its torsional stiffness and dynamic behaviour. Installing an element with an incorrect Shore hardness can change how the complete drivetrain responds to vibration and torque fluctuations.

The coupling type is equally important. Two elements of the same nominal size may use different mounting systems, hole executions, hubs, inserts or flywheel connections.

For critical marine, generator and industrial applications, the replacement should correspond with the original equipment specification and any available torsional vibration analysis.

Genuine CENTA Replacement Parts

AWELASTIC supplies new, original CENTA coupling elements and related replacement components. Product pages show the available size, type, Shore hardness, stock status and other relevant identification information.

Using an original element helps preserve the dimensions, material characteristics and drivetrain behaviour specified for the installed coupling system.
