Description
Rotary Shaft Oil Seal | Double Lip | Shaft Diameter (20mm) x Bore Diameter (40mm) x Width (7mm) | Nitrile Rubber Lip Material.
Product Overview:
The Rotary Shaft Oil Seal with dimensions 20mm (shaft) x 40mm (bore) x 7mm (width) is designed for efficient and reliable sealing in rotary motion systems. Featuring a double lip configuration, it offers superior protection by retaining internal lubricants and keeping out external contaminants like dust, dirt, and moisture. The sealing lip is made from durable Nitrile Rubber (NBR), which is known for its excellent resistance to petroleum-based oils, greases, and wear. This oil seal is ideal for compact mechanical systems where tight tolerance and reliable performance are critical.

Frequently Asked Questions (FAQs):
Q1: What are the benefits of using a double lip oil seal?
A1: The double lip offers two points of sealing—one lip retains lubricant, while the second lip protects against contaminants like dust and moisture, extending the service life of the equipment.
Q2: Why is Nitrile Rubber (NBR) a preferred material for oil seals?
A2: NBR is cost-effective and offers excellent resistance to petroleum-based fluids, greases, and general wear. It is ideal for applications operating in temperatures between -30°C and +100°C.
