ROCKTOOLS SLEEVE

The threaded connection sleeve has been made of high quality alloy steels and CNC processing guarantees our reliable and consistent quality control of the sleeves.
Thread dimensions: R22, R25, R28, R32, R35, R38, T38, T45,T51;
Two categories: Standard connecting sleeves, adapter (cross) sleeves;
The semi-bridged clutching, the most popular one until today, has a small, non-threaded bridge in its center. The driller bar cannot pass through the center of the couplings, and smaller diameter bar sections are connected to each other in the central bridge region of the coupling. Semi-bridge couplings are the most appropriate ones for high torque machines. Most of the rope (R) and Trapezoidal (T) threaded connections are semi-bridged.
The full-bridged coupling provides a great advantage in positively eliminating the creep potential of the coupling through the threaded connections. These clutches are typically used in a Trapezoidal thread, in surface drilling application; they have better dissolution properties and tend to maintain tighter connections.¬ In full bridged clutches, there is less possibility of jamming and they are best suited for machines with independent rotation.
Adapter couplings are used when switching from one gear type or size to another and they are generally required only in special circumstances.
