Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (25mm) x Bore Diameter (40mm) x Width (7mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal 25x40x7mm is a high-quality sealing solution designed to protect rotating shafts and prevent lubricant leakage in mechanical systems. Featuring a double lip design, this oil seal offers dual sealing action—retaining oil on the inside and excluding dirt, dust, and other contaminants from entering the system. The seal is constructed with a steel-reinforced outer shell and Nitrile Rubber (NBR) lips, providing excellent resistance to petroleum-based oils, greases, and wear. It is ideal for a wide range of automotive, industrial, and agricultural applications operating under moderate speed and temperature conditions.

❓ Frequently Asked Questions (FAQs):
Q1: What does the double lip on this oil seal do?
A1: The primary lip retains the lubricant inside the system, while the secondary dust lip blocks out dirt, moisture, and other contaminants for longer service life.
Q2: What is NBR and why is it used?
A2: Nitrile Rubber (NBR) is an elastomer that resists petroleum-based fluids, greases, and wear, performing well in temperatures from -30°C to +100°C.
