Coupling sleeves

Coupling sleeves

High quality of alloy steel and CNC machining guarantee our reliable and consistent quality control of coupling sleeves.

Thread size: R22, R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38, T45, T51.

Bridge type: Semi-bridge, Full bridge.

Full-Bridge Coupling

• Eliminates the potential for the coupling to 

creep along the threaded joints

• Typically used in surface applications

• Better uncoupling characteristics and tends to 

maintain tighter joints 

• Less chance of jamming

• Best suited to machines equipped with 

independent rotation (ie., S36IR rockdrill)

Semi-Bridge Coupling

• Small non-threaded 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-bridged couplings are most suited to 

high-torque machines 

• Most rope and HM threaded couplings are 

semi-bridged

• Best energy transfer
