Männänvarret

Männänvarret, often translated as piston rods, are a critical component in reciprocating engines and hydraulic/pneumatic cylinders. Their primary function is to transmit the linear motion of a piston to another part of a mechanism or to convert linear motion into rotational motion through a connecting rod and crankshaft. These rods are typically made from strong, durable materials like steel or aluminum alloys to withstand the significant forces and stresses they experience during operation.

The design of a männänvarsi is generally straightforward, consisting of a cylindrical rod with a connection point at each end. One end is directly attached to the piston, while the other is connected to a crosshead or a crankshaft assembly via a connecting rod. Precision machining is essential to ensure smooth operation, minimize friction, and prevent premature wear. The surface finish and dimensional accuracy are crucial for optimal performance and longevity of the entire assembly. Männänvarret are found in a wide range of applications, including automotive engines, industrial machinery, pumps, and compressors.
