Disc couplings
OVERVIEW
John Crane’s Metastream® disc couplings
John Crane’s Metastream® power transmission disc couplings perform reliably whether operating remotely in sub-zero temperatures of Alaska, the dusty heat of the Middle East or the corrosive environment of the North Sea.
John Crane’s broad range of power transmission disc couplings is designed to:
- Transfer torque accurately
- Accommodate misalignment
- Eliminating the need for lubrication
- Support equipment performance to ensure they operate safely and reliably

IN MORE DETAIL
John Crane Metastream® disc couplings in more detail
Our T-series disc couplings are fully compliant with API 610 and can be supplied to meet API 671 requirements.
For turbomachinery applications where full API 671 compliance is required as standard, John Crane offers high-performance H-series disc couplings.
The L-series disc couplings are perfect for general industry applications.
John Crane Metastream® disc couplings feature a multiple-disc (membrane) design that does not require any lubrication.
The industry-leading scalloped disc helps improve the efficiency of your equipment.
Applications for disc couplings include centrifugal pumps, ANSI pumps, mixers and agitators.

Common questions
What is a disc coupling?
A disc coupling is a type of power transmission coupling that uses thin metal discs to transmit torque between rotating shafts. John Crane Metastream® disc couplings are designed to accommodate misalignment while providing accurate, slip-free power transmission in demanding applications.
What is a metal disc coupling?
A metal disc coupling is a high-performance, flexible coupling used to connect two rotating shafts without lubrication. John Crane’s metal disc couplings are engineered for high-speed applications and offer reliable performance alongside low maintenance.
How does a disc coupling work?
A disc coupling works by flexing metal discs to accommodate angular, axial and parallel misalignment while transmitting torque between shafts. In John Crane Metastream® disc couplings, the disc pack design enables precise power transmission with minimal reaction forces, helping protect connected equipment and bearings.
How do you install a disc coupling?
Installing a coupling disc involves aligning the shafts, positioning the disc pack correctly and tightening fasteners to specified torque values. John Crane recommends following application specific installation instructions and recognised industry practices to ensure proper alignment, safe operation and reliable performance of disc coupling assemblies.
