Rokee® Customized WJ8 Barrel Coupling for Customers, Rokee® is a well-known high-quality supplier of couplings and technical services in China.
The WJ barrel coupling is a spherical roller flexible coupling designed specifically for heavy-duty lifting equipment, mainly responsible for the power connection between the reducer output shaft and the wire rope drum.
Core Functionality
Composite bearing: synchronous transmission of torque and bearing of radial load
Adaptation to special working conditions: frequent start stop and heavy load impact scenarios such as port gantry cranes, mining hoists, metallurgical casting cranes, etc
System integration advantage: replacing the traditional "coupling+support bearing" split structure, saving installation space by more than 40%
Modular Components
Spherical roller system: composed of high chromium alloy rollers and quenched steel spherical tracks, with a contact fatigue life of>1 million times
Double sealing design: Fluororubber skeleton oil seal+labyrinth seal, suitable for dust/humid environments
Intelligent monitoring interface: optional vibration sensor and temperature probe, real-time data transmission to equipment management system
Dynamic Compensation Mechanism
Angular compensation: The drum tooth design allows for a deviation angle of ± 1.5 °, while the spherical roller structure provides an additional ± 0.5 ° dynamic compensation
Radial floating: The spherical bearing effect can absorb radial displacement of 0.3-1.2mm (depending on specifications)
Anti torsional vibration characteristics: The linear range of torsional stiffness reaches 150% of the rated torque, effectively suppressing start stop impact
Selection Suggestions
Frequent forward and reverse operating conditions require a 20% increase in torque margin
It is recommended to choose WJA type (with dust cover) for environments with high dust levels
Special low-temperature lubricating grease is required for ultra-low temperatures (<-30 ℃)
