If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating or those made of stainless steel.When selecting the shaft hole specification without thread type, the fixing screws are not included.For detailed dimensions of the keyway hole, please refer to 
Technical Data. The position relationship between the keyway and the teeth is not fixed.Processing Method
| Material |  | Cut-off | | Turning |
 |  |  | ||
| Purchase raw materials from material manufacturers and add them to inventory. | Select a rod with a diameter larger than the finished product. Cut to the appropriate size using a cutting machine. | Place the cut blank on the lathe for machining. Form the shape of the gear and make a gear blank. | ||
 | ||||
| Apply anti-rust oil |  | Deburring | | Hobbing |
 |  |  | ||
| Apply rust preventive oil evenly to prevent product rusting. | Remove excess burrs from the gear. To ensure the service life of the gear. | Place the gear blank on the hobbing machine for processing. After hobbing, a large amount of burrs will appear on the gear tooth end face. |
