Crankshafts

Every internal combustion engine has its heart—and that is the crankshaft. It is this component that converts the reciprocating motion of the pistons into rotational movement, powering the entire machine. Without it, no engine will start, and the quality of this part directly affects the power, smoothness of operation, and durability of the power unit.

In our store, you will find a wide selection of crankshafts for machinery, suitable for both popular European models and crankshafts for Chinese machines—excavators, loaders, rollers, or generators. Each product has been designed to withstand extreme working conditions and to work precisely with other engine components.

If you value reliability, smooth operation, and long service life of your equipment—choose a crankshaft from our offer. It is an investment that truly pays off.

Crankshaft – how it works and why it is so important?

Crankshaft is the component that transmits force from the pistons to the drive system. It must withstand enormous loads, operate with perfect balance, and maintain rigidity even at thousands of revolutions per minute. Any imperfection in its manufacturing can lead to vibrations, bearing wear, or even serious engine failures.

That is why it is crucial to choose crankshafts for machinery that meet the highest quality standards and are made from hardened, deformation-resistant steel. The products we offer come from reputable manufacturers and undergo rigorous durability testing. This ensures that the purchased crankshaft will withstand thousands of hours of operation without signs of material fatigue.

Whether you are repairing an excavator, loader, or roller—well-chosen crankshaft is fundamental for a properly functioning engine. Just one solid component can restore the machine’s power and smoothness of operation, just as it was when it left the factory.

Crankshafts for Chinese machines – precision, quality, and fit

The growing popularity of construction equipment from China is no coincidence. Chinese excavators, loaders, and mini-loaders from brands such as Everun, Aps, Gunstig, Wolf, KMM, ZL, Gunter, Kingway, Hercules, or CTM have gained user trust thanks to their robustness and availability of spare parts. However, to fully utilize their capabilities, properly fitted crankshafts for Chinese machines are essential. In our offer, you will find both original Chinese crankshafts and high-quality replacements made according to the same technical specifications.

We offer crankshafts for Chinese loaders and excavators with various capacities and configurations—from small units in mini-loaders to powerful engines used in mining machinery. Our assortment also includes mounting kits: Main bearings, seals, pulleys, bushings, and mounting bolts. Each product has detailed technical specifications and catalog numbers, making it easy to select the right model. If you are unsure which crankshaft for a Chinese machine will fit—our advisors will help you find the perfect solution.

Expert support, fast delivery, and quality assurance

We understand that replacing a crankshaft is a serious service operation—both in terms of time and cost. That is why our store not only offers a wide selection but also reliable technical advice. Our specialists will help you choose a crankshaft tailored to your specific engine model, and if needed—they will suggest which parts to replace during the overhaul (e.g., bearings, seals, or gears). This way, you can avoid situations where the engine needs to be disassembled again after just a few weeks. We also ensure quick order fulfillment—most crankshafts are shipped within 24 hours. We maintain a regular stock of parts for popular brands and models, and for unusual components, we source them on individual order.

Each product is carefully packed and secured for transport, as we know how delicate and precise this component is. This guarantees that you receive a crankshaft ready for installation, free from damage. Our crankshafts for machinery are a solution that works well both in professional workshops and among individual users. Many of our customers confirm that after installation, the engine runs quieter, more smoothly, and regains full power. Don’t risk downtime and costly repairs—choose a proven, durable crankshaft for Chinese loaders and excavators or other construction machinery.
