Dongfeng Cummins C3950549 Piston Pin

The piston pin is used to connect the piston to the connecting rod and transfer the force borne by the piston to the connecting rod or vice versa.

There are three ways to fix the piston pin:

The first uses a floating pin that rotates in both the piston pin seat and the small head of the connecting rod.

Second, the piston pin is fixed to the piston pin seat and can be rotated in the small head of the connecting rod.

Third, the piston pin is fixed on the small head of the connecting rod and can be rotated in the piston pin seat.

A new generation of forging steel technology has created the durability and practicability of Dongfeng Cummins accessories, greatly improving the mechanical strength and wear resistance of products;

The latest precision equipment reduces the error of the product to 0.001, which greatly reduces the distortion of the product.

Floating pin design principle, floating pin design and semi-floating pin and fixed piston pin, compared to the working surface of the relative sliding speed is smaller, the heat generated by friction is correspondingly reduced, wear is smaller and uniform, prolong the life of the floating pin. In addition, the floating pin also has the advantages of not easy to be stuck in the operation and convenient assembly.
