Cylinders in the Cylinders & Pistons category are mechanical components designed to contain and guide the piston's movement, converting compressed fluid or air into mechanical energy. They are fundamental in systems where precision force and motion control are required, such as in hydraulic and pneumatic systems. These cylinders are typically made from strong, durable materials like steel or aluminum to withstand high pressures and repeated use. They come in various types, including single-acting cylinders, which allow movement in one direction, and double-acting cylinders, which enable control of motion in two directions. Cylinders are essential in numerous industrial, automotive, and construction applications, providing the necessary mechanism for lifting, pushing, and pulling actions.
