The Crankshaft and Connecting Rod Assembly forms the core mechanical system of the mud pump's power end, converting rotational input into the controlled linear motion that drives the pistons. This fully integrated assembly features a vacuum-degassed forged steel crankshaft precisely matched with high-strength alloy connecting rods, engineered to work in perfect harmony under the most demanding drilling conditions.

Our assemblies undergo specialized heat treatment and precision machining to achieve optimal fatigue resistance at all critical stress points. Each unit is dynamically balanced to minimize vibration, ensuring smooth power transmission and protecting bearings and other power end components from premature wear. The integrated design guarantees perfect alignment and force distribution, significantly extending service life and reducing the risk of catastrophic failure during continuous operation.
