Features:

These cylindrical pins are equipped with slots along their axial length, allowing elastic deformation during installation, thus facilitating insertion and fixation.
These cylindrical pins are made of carbon steel or other high-strength materials, enabling them to withstand significant tensile and shear forces.
The ends of the pins are machined into chamfered surfaces, making insertion more convenient and reducing the risk of damaging other components during assembly.
Once inserted into a hole, the pins expand slightly, creating an outward tension that secures them tightly against the walls of the hole, ensuring a stable connection.

Advantages:

Thanks to their slotted design and chamfered ends, heavy-duty straight slotted spring pins can be effortlessly inserted into prefabricated holes, eliminating the need for complex installation tools or specialized techniques.
The pins' expansive nature results in a tighter fit against the walls of the hole, enhancing the stability of the connection. This allows it to withstand greater vibration and shock, ensuring durability and prolonging the overall lifespan of the application.
Heavy-duty straight slotted spring pins are designed for ease of installation and removal, making them ideal for use in a wide array of machinery and equipment, particularly in situations where frequent disassembly and reassembly are required, such as in hinges, springs, and power transmission components. Their versatility ensures significant benefits in these applications.

Applications:

Hinge Connections: Heavy-duty Straight Slotted Spring Pins are commonly used in hinge connections, providing a stable connection that allows the hinge to rotate freely when needed.
Spring Fixation: In spring applications, these pins can be used to secure the ends of springs, preventing movement or loosening.
Power Transmission Components: In power transmission systems, heavy-duty straight slotted spring pins are utilized to connect and secure various transmission components, such as gears, shafts, and couplings.
