Description

A piston pin, also called a piston pin or wrist pin, is an important part in internal combustion engines that connects the piston and connecting rod. It acts as a pivot point, allowing the piston to move up and down in the cylinder bore while maintaining its connection to the connecting rod.

Attributes

  • Minimizes friction and wear between pistons
  • Ensures efficient power transmission without excessive energy loss
  • Hardened to a Rockwell C hardness of 58~65 HRC, which gives it resistance to deformation and wear

Applications

The piston pin is used to enable the reciprocating motion of the piston to transmit power.
