Split pins are mechanic union components preventing nuts from unsrewing. They can also be employed to block the linchpins, so that they don’t slip off location.
What are split pins?
Split pins form is similar to a nail ripped in two parts in the longitudinal direction, although it is actually made up of a semicircular metal bar folded over on itself after having formed an eyelet.
The two ends are not of the same length because they are in different sizes, so that the opening is easier.
These are the classic split pins, but there are many different types, for example the elastic split pins.
Elastic split pins
The elastic split pin is also known as Beta Pin (or R-Clip) and it is recognized at a glance by its folded bar. It is specifically composed of a straight part and a shaped part so it can flex without deformation and be re-used.
The straight part goes on the hole, while the shaped part takes hold directly on the spindle.
The elastic spit pin is especially useful in cases where the disassembling and reassembling are very frequent. For this reason, they are often employed in the agricultural processing where machines for tilling the soil down (such as ploughs) or for moving are often interchanged with each other.
