SAE 14 Flywheel Adapter – For CENTAMAX-G Couplings
Showing the single result
The SAE 14 flywheel adapter is an OEM component engineered by CENTA Germany to connect CENTAMAX-G elastic couplings with engines equipped with an SAE 14 flywheel interface (SAE J620).
This adapter ensures correct centering, precise bolt alignment, and stable torque transfer, preserving the torsional behavior defined by CENTA’s engineering.
For the CENTAMAX-G 1800 size, SAE 14 adapters are manufactured from aluminum, combining sufficient structural strength with reduced weight—an advantage in generator and industrial power installations.
SAE 14 Dimensional Data
- SAE Size: 14
- XE – Inner Diameter: 18.375 in (467 mm)
- XF – Bolt Circle Diameter: 17.25 in (438 mm)
- XG – Pilot Depth / Distance to Flywheel Face: 1.00 in (25 mm)
- Tapped Holes: 8
These dimensions follow the SAE J620 standard, ensuring full compatibility with SAE 14 flywheels used by major diesel engine manufacturers.
Fitment & Compatibility
- Adapter Type: CM-G SAE 14
- Compatible Couplings: All CENTAMAX-G 1800 NR and CENTAMAX-G 4600 variants (Shore 50 / 60 / 70 / 72 / 75)
- Material: Aluminum
- Typical Applications:
- Diesel generator sets
- Auxiliary power units (APUs)
- Industrial diesel engines
- Stationary and mobile power systems
Designed specifically for the CENTAMAX-G, this adapter allows seamless installation without modification and maintains correct torsional characteristics between engine and coupling.
Why the Correct SAE 14 Adapter Matters
Using the proper OEM SAE adapter is essential to ensure:
- accurate flywheel centering
- correct axial positioning
- stable vibration behavior
- long coupling service life
- safe torque transmission
Incorrect or non-OEM adapters may lead to misalignment, increased vibration, and premature wear of both coupling and engine components.
