CARDAN SHAFT SET

The CARDANSHAFT SET 5112 3146 03 (also indicated as 5112314603 and 5112-3146-03) is a complete cardanshaft assembly engineered for Epiroc and Atlas Copco drilling rigs, ROC-series platforms, and underground jumbos. The CARDANSHAFT SET 5112 3146 03 includes matched yokes, cross bearings, shafts, and couplings designed to transmit rotary power efficiently between offset or dynamically moving components under severe mining conditions.

This CARDANSHAFT SET 5112 3146 03 is built from high-strength alloy steel with hardened universal joints, precision-machined interfaces, and balanced rotational dynamics. It handles high torque loads, absorbs shock impacts, and remains stable despite vibration, oil contamination, and rock dust exposure. OEM identifiers 5112314603 and 5112-3146-03 ensure full compatibility with Atlas Copco and Epiroc drivetrain systems.

The CARDANSHAFT SET 5112 3146 03 maintains constant torque transfer between engines, pumps, reducers, and drive mechanisms even when machine frames flex or components shift. It prevents power loss, minimizes drivetrain wear, and ensures smooth drilling, feeding, and tramming operations.

Inspect the CARDANSHAFT SET 5112 3146 03 for bearing play, lubrication condition, seal integrity, yoke cracking, and rotational imbalance. Replace 5112 3146 03 immediately if vibration increases, noise develops, or joint stiffness appears.
