CENTAMAX 1800 Coupling | CENTA CM-1800-SB – Highly Flexible Coupling for Diesel Engine Drives
The CENTAMAX 1800 Type SB is a torsionally flexible rubber-in-shear coupling designed for diesel engine drives with high torsional vibrations. Built by CENTA Germany, this size and type are commonly used in large generator sets, marine propulsion systems, and industrial power units where resonance-free operation and long service life are critical.
Key Features & Technical Data
- Coupling type: CENTAMAX SB (single-bearing supported version)
- Nominal torque capacity: 1800 - 2500 Nm (exact value per Shore hardness)
- Shore hardness options: NR typically 50 / 60 / 70
- Material: Natural Rubber (black color)
- Temperature range: –45 °C to +80 °C (NR)
Applications
The CENTAMAX 1800 coupling is widely applied in:
- 🚢 Marine propulsion systems (main drives, thrusters, auxiliaries)
- ⚡ Diesel generator sets for continuous or standby operation
- 🏭 Industrial power units with variable load cycles
- 🚂 Railway traction and auxiliary drives
The SB version is especially suited for engines with free-end bearings, where the coupling itself provides support.
OEM Identification
All genuine CENTAMAX couplings are marked with:
- CENTA logo
- Size (1800)
- Type (SB)
- Shore hardness number
- May also include patent codes
If your current coupling carries these marks, you can be sure it’s an original CENTA element.
