Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (22mm) x Bore Diameter (42mm) x Width (7mm) | Nitrile Rubber Lip Material.
Product Overview
The Rotary Shaft Oil Seal with a Double Lip design and dimensions of 22mm (shaft diameter) x 42mm (bore diameter) x 7mm (width) is designed for reliable sealing performance in compact rotary shaft systems. Crafted from high-quality Nitrile Rubber (NBR) and supported by a steel-reinforced outer case, this seal delivers superior resistance to oils, greases, water, and moderate chemicals. The double lip configuration enhances performance by retaining lubricants and effectively excluding contaminants such as dust, dirt, and moisture — extending equipment life and minimizing maintenance.

❓Questions & Answers
Q1: What is the function of a double lip oil seal?
A: The double lip design provides two sealing edges: the inner lip retains internal fluids such as oil or grease, while the outer lip blocks external contaminants like dust, dirt, and moisture — ensuring greater sealing efficiency and longer service life.
Q2: Why is Nitrile Rubber (NBR) a preferred material?
A: NBR offers excellent resistance to petroleum-based oils, greases, fuels, and many industrial fluids. It also maintains flexibility and durability across a wide range of temperatures, making it suitable for both static and dynamic sealing applications.
