Rotex Couplings
Rotex coupling is a type of flexible coupling that transmits torque between two shafts while damping vibrations through an elastomeric intermediate element (coupling insert – spider). Also known in industry as a “jaw coupling” or “spider coupling,” this coupling type is widely used in applications requiring high-performance power transmission and shock absorption.
Thanks to the elastomeric spider piece positioned between metal hubs, Rotex couplings absorb vibrations and tolerate shaft misalignment, ensuring longer equipment life and stable operation.
Product Features and Advantages
- High torque transmission capacity
- Vibration and shock damping feature
- Ability to tolerate angular, radial, and axial misalignments
- Quiet and vibration-free operation
- Easy installation and quick maintenance
- High resistance to wear and fatigue
- Application-specific solutions with different hardness options
Application Areas
Rotex couplings are used safely in many industrial applications:
Electric motors and gearbox systems
Pump and compressor systems
Fan and ventilation equipment
Conveyor and production lines
CNC machines and automation systems
Textile, food, and packaging machinery
Technical Structure and Material Options
Rotex couplings consist of two metal hubs and an elastomeric spider (coupling insert) element positioned between them. The elastomeric structure absorbs vibrations and shocks in the system, helping to protect the equipment.
NBR (Nitrile Rubber): Resistant to oil and fuel
EPDM: Resistant to water, steam, and outdoor conditions
Polyurethane (PU): High wear resistance and high torque capacity
Silicone: High temperature resistance
Production with different shore hardness values provides application-specific performance.
