Alloy‑Steel Hollow Crankshaft Assembly

Manufactured by Dezhou Yangda Petroleum Machinery Co., Ltd, the alloy‑steel hollow crankshaft is high‑performance Petroleum machinery accessories. It is one of the critical Oil drilling equipment parts for oil‑field drilling and provides core power transmission support for mud pump systems. Finished with advanced CNC precision machining, this item is an essential Mud pump parts. It belongs to Mud pump power end and can fit precisely and cooperate smoothly with Crosshead Assembly and Mud pump fluid end, ensuring stable reciprocating operation of the complete mud pump unit. Forged from high‑strength alloy steel, the crankshaft adopts hollow‑structured main journals and crank pins with an integrated internal oil gallery. After surface quenching and fillet‑rolling strengthening heat treatment, this hollow crankshaft weighs less, features low rotational inertia, reduced running resistance, excellent lubrication performance and outstanding fatigue resistance. It can endure high‑frequency, heavy‑load and continuous impact loads in oil‑field drilling conditions and greatly lower the risk of fracture failure. Strict precision control guarantees good coaxiality with other transmission components, cutting down vibration and wear to extend the mud pump service life. Besides mud‑pump applications, this hollow crankshaft can also serve construction machinery, generator sets and other heavy‑duty power equipment. Dezhou Yangda Petroleum Machinery Co., Ltd offers OEM customization according to customer drawings. All our Mud pump parts go through flaw‑detection and load‑bearing tests before delivery.
