R28 CNC Milling Threaded Rod Coupler Threaded Rod Coupling Sleeve

Description

Standard coupling using R28 thread system

• R25 thread system
• Widely used in drifting and tunneling

Color: Green or Based on Customer requirements

Material: Tungsten carbide and high strength alloy steel

Processing: CNC milling and proprietary heat treatment process

Type: R28 Standard Coupling

Specification and function of the coupling sleeve:

Full-Bridge Coupling sleeve
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
Best suited to machines equipped with independent rotation.

Semi-Bridge Coupling sleeve
Small non-threaded bridge in the center
Steel cannot thread past bridge area
Smaller diameter steel end portions fit together in the centre bridge area of the coupling
Semi-bridged couplings are most suited to high torque machines
Most rope and T threaded couplings are semi-bridged

Same diameter Coupling sleeve
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
Best suited to machines equipped with independent rotation.
