Import Coupling Sleeves — Buy in Bulk from Supplier in China

The coupling sleeves from Kelleg International Trade (Shanghai) Co., Ltd. are engineered specifically for rock drilling applications, serving as a critical link between drill rods or shank rods. These components endure significant mechanical stresses, including axial tension, compression, bending, torsion, and friction, making them essential for efficient stress wave propagation during drilling operations. The supplier offers full-bridge and reducing coupling sleeves, with thread sizes such as R32, R38, T38, T45, and T51.

Manufactured to withstand the extreme conditions of rock drilling, these coupling sleeves are typically produced from high-grade alloy steel to ensure superior strength and wear resistance. Thread structures vary, with options including wave thread, compound thread, and trapezoidal thread, each designed for specific drilling environments and load requirements. The geometric structure may be straight-through, reducing, or middle-stop-type, providing versatility for different drilling configurations.

These coupling sleeves are primarily used in geotechnical anchorage and mining operations, where reliability and precision are paramount. The supplier’s focus on supply chain management and quality control ensures that each component meets the rigorous demands of rock drilling applications.
