Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
SC Oil Seal - Premium Single - Lip Sealing Solution
For Efficient Lubricant Retention and Dust Prevention in Mechanical Systems
The SC oil seal stands out as a premium single-lip sealing solution, engineered to deliver reliable performance for diverse mechanical systems. Its thoughtfully designed structure combines flexible, high-quality sealing elements (typically NBR or FKM) for tight, leak-proof contact and stable support components to maintain shape integrity during installation and operation.
Beyond core sealing, it excels at retaining lubricants to reduce friction and wear, while blocking dust and debris that could harm internal parts. Suitable for industries like automotive, marine, and home appliances, it boosts equipment durability, cuts maintenance needs, and ensures smooth, long-term operation—making it a practical choice for optimizing mechanical efficiency.

1. Product Advantages
Superior Sealing Performance: Crafted with high-quality materials (NBR or FKM), the SC oil seal ensures tight, leak-proof contact with sealing surfaces. It effectively retains lubricants and blocks dust, debris, and external contaminants, reducing equipment friction and wear.
Durable & Stable: The integrated structure of flexible sealing elements and rigid support components maintains shape integrity even under frequent installation and long-term operation. It withstands a wide temperature range (-15℃-200℃ for FKM, -15℃-100℃ for NBR) and pressure up to 0.03Mpa, adapting to harsh working conditions.
Low Maintenance Cost: By preventing lubricant leakage and component damage from contaminants, it extends equipment service life, minimizes downtime for repairs, and lowers overall maintenance expenses for users.
2. Working Principle
The SC oil seal operates on a simple yet efficient mechanism. Its single-lip design, paired with a built-in garter spring (for enhanced contact), creates consistent pressure against the rotating or stationary shaft. When the equipment runs, the flexible sealing lip adheres tightly to the shaft surface, forming a barrier that traps lubricants inside the mechanical system. Simultaneously, the lip blocks external dust, water, and debris from entering, ensuring the internal components stay clean and well-lubricated for smooth operation.
3. Product Details
Material Options: Available in nitrile rubber (NBR) for general-purpose applications (excellent oil resistance) and fluororubber (FKM) for high-temperature, chemical-resistant needs.
Structural Features: Single sealing lip with garter spring, reinforced metal or composite support ring (ensures easy installation and shape stability), and precision-machined sealing surface (guarantees tight fit).
Performance Parameters: Maximum speed up to 12M/S, compatible with most industrial lubricants, and meets international quality standards for dimensional accuracy.
4. Application Range
Ideal for sealing scenarios across multiple industries, including:
Automotive: Engine crankshafts, camshafts, and transmission systems.
Marine & Railway: Propulsion systems, gearboxes, and hydraulic components of ships and railway vehicles.
Home Appliances: Motors in washing machines, air conditioners, and refrigerators.
Industrial Machinery: Pumps, compressors, and gearboxes in manufacturing plants.
5. FAQ
Q1: Can the SC oil seal be used for high-temperature applications?
A1: Yes. Choose the FKM material option, which withstands temperatures up to 200℃, suitable for high-heat environments like engine compartments.
Q2: How to select the right size of SC oil seal?
A2: Provide the shaft diameter, housing bore diameter, and seal width to our sales team—we offer customized sizing to match your equipment.
Q3: What is the service life of the SC oil seal?
A3: Under normal working conditions, NBR seals last 1-2 years, while FKM seals can last 2-3 years. Service life may vary based on temperature, pressure, and lubricant type.
