    Pins have the functions of positioning, connecting, locking, and even dismantling. In addition to the basic cylindrical pins and tapered pins, pins also have slotted pins, split pins, pins, safety pins, etc., which are widely used in life.

    In machinery, pins are mainly used for assembly positioning, and can also be used as overload shear connections in connection and relaxation level safety devices. The types of pins are cylindrical pins, tapered pins, hole pins, cotter pins, and safety pins. Tapered pins and cylindrical pins are the most common in everyday life. What is the difference between the two?

    1、Different treatments. Cylindrical pins can be preconditioned; tapered pins usually match.

    2、Cylindrical pins are usually suitable for precise positioning (machined first); tapered pins are often used for frequent disassembly.

    3、Cylindrical pins can play a role in shear resistance; tapered pins are usually used for positioning.

    4、The cylindrical pin is fixed in the reaming hole, the interference is small, and it can bear a small load. In order to ensure the positioning accuracy and the tightness of the connection, please do not disassemble frequently. It is mainly used for positioning, and can also be used as connecting pin and safety pin. The taper of the tapered pin is 1:50, which has good self-locking performance and high positioning accuracy. It is easy to install and has little effect on positioning accuracy. It is mainly used for positioning and can also be used as a connecting pin. The pin holes require reaming.
