T38-190 mm Coupling Sleeves for Mining and Rock Drilling

Our comprehensive range of rock drilling tools includes adapter couplings, cross-over adapter couplings, and coupling sleeves designed for demanding mining and drilling applications.

Coupling Sleeves Overview

Coupling sleeves (also known as couplings) are essential components when using rock drills with male shank adapters and conventional drifter rods. They connect the adapter to the rod, ensuring proper contact for efficient energy transmission. Couplings can also connect multiple rods together and feature a middle stop to prevent over-threading onto drill rods. We manufacture both semi-bridge and full bridge coupling sleeves for percussive tools.

Semi-Bridge Coupling Features

Semi-bridge couplings are the most commonly used type in the market, featuring:

Small non-threaded bridge in the center
Steel cannot thread past bridge area
Smaller diameter steel end portions fit together in the center bridge area
Most suitable for high torque machines
Most rope and HM threaded couplings are semi-bridged

T38-190 semi-bridge type coupling provides reliable performance in demanding conditions.
