How much do you know about oil seal selection considerations? Let's follow the editor of Best The plane oil seal together to have a simple understanding!
1. Movement direction: first determine the movement direction of the oil seal at the internal position of the engine oil seal, such as reciprocating, rotating, screwing or fixing;
2. Sealing concerns: for example, it is determined that the active point is the tie rod seal of the inner diameter or the active point of the sealed bearing is the piston seal of the outer diameter;
3. Temperature grade: refer to the original mechanical operating instructions or evaluate the working temperature according to the actual working environment, and decide the required materials. For the description of the temperature grade, please refer to the precautions;

4. Pressure level: Check the relevant data from the original long mechanical operating instructions, or infer the working pressure level by observing the hardness and structure of the crude oil seal, and refer to the precautions for the description of the pressure level;
5. Size: Most users will buy according to the old samples that have been used, but for example, the skeleton oil seal will be greatly affected by factors such as temperature, pressure and wear after a period of use. The original size can only be selected as one. For reference, a better method is to measure the size of the metal groove where the oil seal is located, and the accuracy will be higher;
The above is the editor of Best The plane oil seal: a brief introduction to the knowledge about the precautions for oil seal selection.
