Frequently Asked Questions

What is the primary function of these couplings?

Couplings are used to connect extension rods, transmitting impact energy and rotation torque from the rock-drill piston to the drill string with minimal energy loss.

What materials are used for manufacturing?

The products are manufactured using high-quality Carbon Steel and 23crni3mo alloy through a precision forging and spray-painting process.

What thread types and sizes are available?

We offer a wide range of thread sizes including R22, R25, R28, R32, R38, T38, T45, and T51, including cross-over sizes like R25-R32.

How are the products packaged for delivery?

Standard packaging involves secure wooden cases or cartons to ensure safe transport. The typical package size is 30x30x30cm with a gross weight of approximately 5kg.

What is the monthly production capacity?

Our manufacturing facility has a production capacity of 500,000 pieces per month to meet large-scale industrial demands.

Can these couplings withstand high-frequency impacts?

Yes, they are designed to withstand and transmit up to 6,300 blows per minute from the piston with high endurance and dependability.
