Description
Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (50mm) x Bore Diameter (80mm) x Width (8mm) | Nitrile Rubber Lip Material.
Product Overview:
Rotary Shaft Oil Seal | 50x80x8mm | Double Lip | Nitrile Rubber (NBR)**
The Rotary Shaft Oil Seal – Double Lip (50x80x8mm) is a high-performance sealing component engineered to provide effective barrier protection in rotary shaft applications. Its double lip design, along with an integrated garter spring, ensures continuous radial contact with the shaft surface for optimal sealing performance—helping retain lubricants and exclude dust, dirt, and moisture.
Made with Nitrile Rubber (NBR) for the sealing lips, this oil seal resists oils, greases, light chemicals, and abrasion. The steel-reinforced inner core maintains structural stability, while the rubber-coated outer diameter guarantees a secure and vibration-resistant fit in the housing bore. Designed for a shaft diameter of 50mm, bore diameter of 80mm, and width of 8mm, it’s ideal for medium-duty rotating machinery in both industrial and automotive environments.

❓ Questions & Answers:
Q1: What is the purpose of a double lip in an oil seal?
A1: The double lip configuration provides two lines of defense: the primary lip retains the lubricant inside, while the secondary lip prevents contaminants from entering, improving overall reliability and service life.
Q2: What is the seal lip made from?
A2: The lip is made from Nitrile Rubber (NBR), a durable material known for its excellent resistance to oil, grease, and wear, making it ideal for automotive and industrial applications.
