Piston Skirt

The cylindrical portion of the piston between the last scrapper ring and the open end is called the piston skirt. The piston skirt acts as a bearing surface for the side thrust. The length of the skirt should be such that the bearing pressure due to side thrust is restricted to 0.2 MPa on the projected area. In high-speed engines, the bearing pressure up to 0.5 MPa is allowed to reduce the weight of the reciprocating piston. The maximum side thrust will occur during the expansion stroke.
