Description
Double lip dustproof oil seal is an oil seal designed with double sealing lips, which is specially used to prevent external dust, dirt, moisture, etc. from entering the interior of mechanical equipment and protect the lubricating oil or liquid of the equipment from contamination. It is commonly used in automobiles, engineering machinery, industrial equipment and other fields, and can effectively extend the service life of bearings and other seals. Double lip dustproof oil seal has strong sealing performance and is suitable for use in harsh working environments, especially in places where dust and dirt need to be prevented from invading. Its design not only focuses on the sealing effect, but also provides additional dust protection, delays equipment failure and reduces maintenance costs.

Production
Process
Metal frame manufacturing
The oil seal frame is made of high-strength metal or reinforced materials to ensure its structural strength and stability.
Rubber molding
According to the design requirements, select appropriate rubber materials (such as NBR, FKM, etc.) for molding to ensure that the sealing lip of the oil seal has good elasticity, wear resistance and oil resistance.
Vulcanization
The vulcanization process enhances the rubber's resistance to high temperatures, wear and aging, ensuring the stability of the product in long-term use.
Finishing and assembly
The sealing surface of the oil seal is precisely machined to ensure a good sealing effect and correct size.
Quality Inspection
Each product undergoes rigorous performance testing to ensure that temperature resistance, sealing and pressure resistance meet standards.
Packaging and delivery
The products are cleaned and packaged to ensure they are not damaged during transportation.
