1、 Definition of sales axis
A pin shaft is a mechanical connector composed of two parts. One of the parts is a pin, usually circular, and the other part is a shaft sleeve or hole sleeve, usually a circular hole. One end of the pin has a head, which is inserted into another part through the hole or passage of the shaft sleeve or hole sleeve. A pivot pin is used to connect two or more components, allowing them to move relative to each other along the axis of the pivot pin.

2、 Application fields of sales shafts
The sales shaft is widely used in various mechanical fields, such as automobiles, construction machinery, agricultural machinery, ships, machine tools, electrical appliances, household products, etc. For example, a pivot pin can be used as a component of a vehicle engine or as a fastener in furniture manufacturing.
3、 Is it a standard part
Pins are usually customized and manufactured according to the needs of their application field, so they cannot be completely classified as standard parts. However, some shafts can also be produced according to national and industry standards, and these shafts that meet the standards can be considered standard parts. In any case, for reasonable use and maintenance, appropriate specifications and models should be selected based on specific circumstances.
In summary, the pin shaft is a mechanical connector widely used in various mechanical fields. Although shafts can sometimes be produced according to standards, they are usually customized and manufactured according to the needs of the application field. Mastering the correct method of using the pivot pin is one of the key factors in ensuring the smooth operation of the mechanical system.
