Eccentric Shafts & Crank Shafts

The four primary types of forging are open-die forging, closed-die (impression-die) forging, seamless rolled ring forging, and cold forging. Open-die forging shapes metal between flat dies, while closed-die forging uses shaped dies for greater precision. Ring forging produces circular components, and cold forging forms metal at room temperature for tight tolerances. Krupa Services utilizes forging and machining processes to produce high-strength eccentric and crank shafts.

Eccentric and crank shafts can be manufactured from a variety of metals depending on the application requirements. Common materials include carbon steel, stainless steel, brass, copper, and aluminum. Steel and stainless steel are preferred for high-strength, high-torque applications such as automotive and mining equipment, while aluminum offers a lightweight alternative for less demanding or weight-sensitive applications.

Yes. Krupa Services offers full customization of eccentric and crank shafts based on customer-supplied specifications. This includes material selection, dimensional tolerances, surface finishes, and geometry. Whether you require prototypes for component development or high-volume production runs, the engineering team can work with you to deliver components that meet your exact technical and performance requirements.

Eccentric shafts and crank shafts are critical components across multiple industries. They are used in automotive transmission systems, mining and crushing equipment, construction machinery, agricultural equipment, industrial machinery, and off-highway vehicles. Their ability to convert rotational motion into precise oscillating or reciprocating force makes them indispensable in any application requiring controlled mechanical movement.

An eccentric shaft features a cylindrical section whose center is offset from the shaft's rotational axis, producing a cam-like motion ideal for crushers and compressors. A crankshaft converts rotational motion into linear reciprocating motion through its crank throws and journals, and is most commonly found in internal combustion engines and piston-driven machinery. Both are precision-forged components requiring tight dimensional control.

Pricing and lead times for eccentric shafts and crank shafts vary based on material selection, complexity, tolerances, and order volume. Krupa Services provides pricing on request and is committed to timely delivery through streamlined production systems and a robust global supplier network.
