Coupling Components

Underground Mining Coupling Sleeve R25 R28 R32 R38 T38 T45 T51 Forging Processing

Underground Mining Coupling Sleeve R25 R28 R32 R38 T38 T45 T51 Forging Processing

Semi-Bridge Coupling

Small non-thread bridge in the center

Steel cannot thread past bridge area

Smaller diameter steel end portions fit together in the center bridge area of the coupling

Semi-bridge coupling are most suitable to high orque machines
Underground Mining Coupling Sleeve R25 R28 R32 R38 T38 T45 T51 Forging Processing

Full-Bridge Coupling

Eliminates the potential for the coupling to creep along the threaded joints

Typically used in surface applications

Better uncoupling characteristics and tend to maintain tighter joints

Less chance of jamming

Adapter Coupling

Used when changing from one thread type, or size, to another and are typically required only in special circumstances
