Industrial Rotary Shaft Seal – Applications
The 17x28x7 NBR AO TC double lip oil seal is a precision-engineered rotary shaft seal designed to deliver effective sealing performance in demanding mechanical environments. With dimensions 17 mm inner diameter x 28 mm outer diameter x 7 mm width, this oil seal is ideal for a wide range of industrial applications, including gearboxes, pumps, motors, compressors, automotive assemblies, and hydraulic systems where reliable fluid retention is critical.
This shaft sealing ring features a double lip (AO TC) construction that enhances sealing efficiency. The primary lip delivers robust protection against lubricant escape, while the secondary lip helps prevent contamination from dust and debris. Such design improves the lifespan of bearings and other rotating components by maintaining optimal lubrication and preventing premature wear.
Manufactured from high-quality NBR (nitrile butadiene rubber), this technical seal provides excellent resistance to oils and grease, as well as stable performance across a broad temperature range. Its resilience to industrial fluids makes it suitable for heavy-duty operations in automotive, manufacturing, and hydraulic applications.
Advantages – High Durability and Seal Performance
• Enhanced Double Lip Design: The AO TC double lip configuration improves dynamic sealing capability, offering superior retention of lubricants and resistance to ingression of contaminants.
• Material Resilience: NBR elastomer provides strong resistance to oils, greases, fuels, and many industrial fluids, ensuring long-lasting performance in rotary shaft sealing.
• Industrial Reliability: Designed for continuous rotation and oscillation, this oil seal delivers high durability even in rigorous working conditions.
• Versatile Use Cases: Suitable for automotive engines, gearboxes, pumps, compressors, and other heavy machinery requiring dependable rotary sealing solutions.
• Precision Fit: Accurate dimensions ensure effective contact pressure and consistent seal performance, reducing the risk of leakage and maintenance downtime.
This double lip oil seal stands out as a reliable engine seal and general-purpose rotary sealing solution, balancing tight sealing performance with resistance to mechanical wear. Its versatility and robust construction make it a preferred choice for engineers and procurement specialists focused on long-term system integrity.

FAQ – Common Technical Questions
1. What is a double lip oil seal (AO TC)?
A double lip oil seal uses two sealing edges: a primary lip to retain lubricant and a secondary lip to block dust and external contaminants for better overall performance.
2. How does this seal differ from a single lip oil seal?
Double lip seals offer enhanced protection against contamination while maintaining lubricant retention, whereas single lip seals primarily focus on fluid retention.
3. Can this oil seal handle high speeds and harsh conditions?
Yes, the NBR material and double lip design are engineered for industrial applications involving continuous rotation and moderate to high operating speeds.
4. Which industrial systems use this type of rotary shaft seal?
Common systems include hydraulic pumps, automotive transmissions, electric motors, gear assemblies, compressors, and other machinery requiring reliable shaft sealing.
5. How do I choose the correct oil seal size?
Verify the shaft diameter, housing bore, and required width. This seal’s dimensions – 17x28x7 mm – must match the system’s specifications for proper sealing effectiveness.
