Rotary Shaft Oil Seal | Double Lip |  Shaft Diameter (20mm) x Bore Diameter (38mm) x Width (8mm) | Nitrile Rubber Lip Material.

Product Overview:

The Rotary Shaft Oil Seal Double Lip (20 mm shaft diameter) is designed for compact mechanical systems requiring reliable sealing performance. This seal prevents the leakage of lubricants and protects against the ingress of external contaminants. The double lip design enhances operational life by combining effective fluid retention with environmental sealing.

Manufactured using Nitrile Rubber (NBR), the seal offers excellent resistance to oils, greases, and general wear. Its 8 mm width allows it to fit into narrow housings without compromising sealing integrity. Ideal for small machinery, this seal delivers robust performance in high-speed, light-duty rotary applications.

Questions and Answers: Shaft Oil Seal

Q1: What makes a double lip seal better than a single lip seal?


A1: A double lip seal includes a secondary lip that adds protection against external contaminants such as dust and moisture, while the primary lip retains lubricant — increasing overall seal life and reliability.

Q2: Why is Nitrile Rubber a good material for this application?


A2: NBR is cost-effective and resistant to oil, grease, and abrasion, making it well-suited for small machinery that uses lubricants and operates in moderate temperature ranges.
