Carbon steel crescent key, half-circle pin key, half-moon key

Brief description of semicircular key pin:
Semi-circular key pins are mainly used for connections in mechanical transmission to transmit torque or bear loads. It can be used to connect the shaft and the hub so that the two can rotate together and can withstand certain radial and axial loads. Half-round keypins are usually installed in keyways, which can be machined into the shaft or hub. Semi-circular key pins have the characteristics of simple structure, easy installation, and large load-bearing capacity, so they have been widely used in mechanical transmission.

When using half-circle key pins, you need to pay attention to the following points:

1. Select the appropriate key size and type to ensure it can withstand the required load and torque.
2. When installing the semi-circular key pin, it is necessary to ensure that the keyway is clean and flat to avoid impurities and burrs that may affect the installation quality.
3. When installing the semi-circular key pin, you need to use appropriate installation tools and methods to avoid damaging the key pin or keyway.
4. During use, it is necessary to regularly check the tightening and usage status of the semicircular key pins, and promptly replace damaged or severely worn key pins.

In short, the semi-circular key pin is an important mechanical transmission connection component. When using it, you need to pay attention to selecting the appropriate model and size, follow the correct installation method, and perform regular inspection and maintenance to ensure that it can work properly and extend its service life.
