Product Description
NM50-265 NBR Polyurethane Coupling for Industrial Metal Shaft Applications
The NM50-265 Polyurethane Coupling is engineered for industrial metal shaft connections, featuring advanced NM-type rubber coupling technology for superior performance and durability.
Structure and Design
The NM-type rubber coupling consists of two cast iron half-couplings and an intermediate rubber elastomer:
- NM Rubber Coupling Spider: Spider-shaped elastomer with multiple claw structures that interlock with the half-couplings' convex claws for secure torque transmission
- NM Rubber Element: Key rubber components made from specially designed synthetic nitrile rubber (NBR) that provide the coupling's elastic functionality
Key Features and Benefits
| Superior Shock Absorption | Effectively absorbs vibration and impact, reducing equipment damage and extending service life |
| Excellent Oil & Chemical Resistance | Nitrile rubber provides outstanding resistance to oils, acids, alkalis, and chemical solvents |
| High Wear Resistance | Maintains transmission efficiency and stability even under long-term, frequent use |
| Easy Installation & Maintenance | Simple design allows for quick installation and disassembly, reducing downtime |
| Shaft Misalignment Compensation | Compensates for axial, radial, and angular deviations during installation and operation |
Industrial Applications
This coupling is widely used across multiple industrial sectors:
- Pump Systems: Centrifugal pumps, gear pumps, screw pumps for connecting pump and motor shafts
- Fan Equipment: Centrifugal fans, axial fans to reduce vibration and ensure stable operation
- Compressors: Air compressors, refrigeration compressors handling high torque and intermittent loads
- Transportation Machinery: Conveyors, elevators, cranes ensuring smooth power transmission
- General Industrial Equipment: Mixers, crushers, reducers, printing machines, textile machinery
Technical Specifications
Available in standard outer diameter sizes: 50mm, 67mm, 82mm, 97mm, 112mm, 128mm, 148mm, 168mm, 194mm, 214mm
Performance Advantages
| Economical & Practical | Cost-effective solution for various industrial applications |
| Quiet Operation | Smooth performance with minimal noise generation |
| High Torque Capability | Suitable for machines with high torque and intermittent operation |
| Advanced Material Properties | Synthetic rubber provides proper elasticity and resistance to damping, oil, acids, and alkalis |
Industry Applications
Serving multiple sectors including mining, metallurgy, cement, chemicals, construction, building materials, power generation, telecommunications, textiles, and transportation.
