CENTAMAX-G Size 1800 – OEM Torsionally Flexible Couplings & SAE Flywheel Adapters
CENTAMAX-G 1800 series is a torsionally flexible coupling system developed by CENTA Germany for diesel generator sets, auxiliary power units, and medium-to-high power industrial drives.
Positioned in the mid-range of the G-Series, Size 1800 combines high vibration damping, compact dimensions, and reliable torque transmission, making it one of the most frequently used CENTAMAX-G sizes in generator applications.
This size category includes:
- CENTAMAX-G 1800 elastic coupling elements (NR, multiple Shore hardness options)
- Taper-lock hubs (Taper 3535, Stiebel version available)
- SAE flywheel adapters for common generator flywheel standards
All components are engineered to work together as a system, ensuring correct torsional behavior, precise alignment, and long service life.
Key Characteristics of CENTAMAX-G 1800
Optimized for Generator Drives
Size 1800 is specifically tuned for generator systems where torsional vibrations, load fluctuations, and thermal stability must be controlled to protect both the engine and alternator.
High Damping with Stable Torque Transfer
The natural rubber elastic element absorbs torsional peaks and smooths rotational irregularities, supporting stable generator output and reducing stress on connected machinery.
Taper-Lock Hub System (3535)
CENTAMAX-G 1800 typically uses the Taper-Lock 3535 hub, providing:
- fast and repeatable installation
- accurate shaft centering
- secure torque transmission
- simplified maintenance and replacement
A Stiebel hub version is also available for specific installations.
SAE Flywheel Compatibility
Size 1800 couplings can be combined with OEM SAE flywheel adapters, supporting multiple SAE standards commonly used in generator engines.
Adapters ensure correct centering, bolt-pattern matching, and safe torque transfer between engine flywheel and coupling.

Technical Overview – CENTAMAX-G 1800 (NR)
(Values depend on Shore hardness: 50 / 60 / 70 / 72 / 75)
- Rubber Quality: Natural Rubber (NR)
- Nominal Torque (TKN): 1,800 – 2,800 Nm
- Maximum Torque (TKmax): 3,600 – 7,000 Nm
- Continuous Vibratory Torque (TKW): 720 – 1,120 Nm
- Permissible Power Loss (PKV): 265 – 330 W
- Dynamic Torsional Stiffness: 6,600 – 140,000 Nm/rad
- Relative Damping: 1.05 – 1.40
- Maximum Speed (nmax): 3,000 – 3,200 rpm
- Standard Hub: Taper-Lock 3535
- Alternative Hub: Stiebel version available
- Flywheel Compatibility: SAE standards (via adapters)
These parameters make Size 1800 suitable for engines where torsional tuning is critical but space and weight must remain controlled.
Typical Applications of CENTAMAX-G 1800
- Industrial diesel generator sets
- Marine auxiliary gensets
- Standby and emergency power units
- Mobile generator containers
- Industrial engines driving pumps, compressors, or fans
The combination of torsional softness and compact size makes CENTAMAX-G 1800 a reliable OEM solution across many generator platforms.
Why Use Original CENTAMAX-G 1800 Components
Only genuine CENTA Germany components guarantee:
- correct Shore hardness and stiffness curves
- torsional behavior validated through TVA
- compatibility between elastic element, hub, and SAE adapter
- predictable damping and thermal performance
- long service life in continuous-duty generator operation
Non-original alternatives often deviate in stiffness and damping, increasing the risk of resonance, vibration issues, and premature coupling failure.
AWELASTIC supplies OEM-only CENTAMAX-G 1800 elements, hubs, and adapters, ensuring correct system performance.
