Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (8mm) x Bore Diameter (21.5mm) x Width (10mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal 8x21.5x10mm is a compact and high-performance sealing component engineered for small rotary shafts. With its double lip configuration, this seal offers enhanced protection by retaining lubricants within the system while effectively blocking out contaminants such as dust, dirt, and moisture. Built from durable Nitrile Rubber (NBR) and supported by a steel-reinforced outer casing, this oil seal ensures secure fitment and long-lasting resistance to oils, greases, and wear. It is ideally suited for use in precision equipment, automotive parts, motors, and hydraulic systems.

❓ Frequently Asked Questions (FAQs):
Q1: What does the double lip do in this rotary shaft seal?
A1: The primary sealing lip retains internal lubrication, while the secondary (dust) lip prevents contaminants like dirt and moisture from entering the system.
Q2: Why is Nitrile Rubber (NBR) used in this oil seal?
A2: NBR offers excellent resistance to petroleum-based oils, greases, and moderate chemicals, and functions reliably in temperatures from -30°C to +100°C.
