The Mitsubishi 4140A302 is a premium quality coil spring designed for industrial and commercial applications. This spring, manufactured by Mitsubishi Heavy Industries, is engineered to deliver exceptional performance and durability.

This coil spring boasts a diameter of 41.4 millimeters and a length of 302 millimeters. The wire diameter used in its construction is 8.5 millimeters.

The steel undergoes a series of rigorous processes to ensure its strength and uniformity. These processes include heat treatment, tempering, and shot peening. The result is a spring that not only performs consistently but also maintains its shape and resilience over extended periods.

This particular coil spring from Mitsubishi features a square-wave spring profile, which provides a more uniform load distribution compared to other spring shapes. This profile allows the spring to handle heavy loads more efficiently while minimizing deflection and ensuring accurate positioning.

The Mitsubishi 4140A302 coil spring is designed for use in various industries and applications, including manufacturing, automotive, construction, and agriculture. It can be used to support heavy machinery, provide tension or compression, or act as a damper in hydraulic systems.

In conclusion, the Mitsubishi 4140A302 coil spring is a top-tier industrial component, offering superior performance, durability, and load capacity. Its precise dimensions, high spring rate, and robust construction make it an excellent choice for heavy-duty applications where reliability is essential.
