Curved Jaw Couplings
The TransDrive Curved Jaw Couplings also known as GE or CJ, are a compact, lightweight solution engineered for high-torque and high-speed industrial applications. Their advanced design includes crowned spider elements, which enhance torsional flexibility and improve the ability to accommodate misalignment between shafts.
Available with three types of durable urethane elements, these couplings deliver higher power ratings than traditional straight jaw designs, making them ideal for demanding operating conditions.
TransDrive Curved Jaw Couplings come in two hub configurations-pilot bore and taper fit ensuring quick installation and easy replacement. Each complete coupling assembly consists of two hubs and one elastomeric element (commonly referred to as a spider), with taper fit hubs requiring additional bushes.
Designed to minimise vibration and maximise efficiency, TransDrive Curved Jaw Couplings provide reliable power transmission across a wide range of industrial machinery.
Features & Benefits
- High Torque capacity for size
- Compact design
- Low weight for reduced inertia
- Machined surfaces for extended life
- Absorbs shock loads
- Vibration dampening
Coupling Model Selection
- Refer to the Power Rating tables.
- Select the Element type “Yellow 92A Shore”, “Red 98A Shore” or “Green 64D Shore”.
- Read down the left column to the required speed then read across horizontally until the design power is exceeded to select the coupling model. If the exact speed is not shown calculate based on power rating per/100rpm shown in the first column.
Bore Dimensions
Check maximum bore dimensions and select from:
- Pilot Bore model to be machined to required bore or key or
- Taper Bore option.
Selection via Torque Calculation Method
Torque
Calculate torque applied to the coupling by this formula.
Service Factor
Apply the service factor to the torque figure in Nm, this is the design torque rating.
Coupling Torque Ratings
Check the torque ratings for the Yellow 92A Shore, Red 98A Shore or Green 64D Shore as shown in the dimensions tables on Elements. Select a suitable coupling that exceeds the design torque rating.
Bore Dimensions
Check maximum bore dimensions and select from pilot bore model to be machined to required bore and key or taper fit option in available metric and imperial bore sizes.
