Product Overview:
The Rotary Shaft Oil Seal (21mm x 40mm x 10mm) features a double lip (TC style) design that combines effective fluid sealing with protection from external debris. It is made with Nitrile Rubber (NBR) and reinforced with a steel case, making it ideal for medium-speed rotary applications exposed to oils and greases.

❓ Frequently Asked Questions (FAQs)
Q1: What is the function of the double lip?
A: The primary lip seals in the lubricant, while the secondary lip prevents dust and contaminants from entering the system—extending the life of both the seal and the internal components.
Q2: Can this Oil Seal handle high temperatures?
A: Yes, it can operate reliably between –40°C and +120°C, which covers most industrial environments.
Q3: Is this Oil Seal reusable?
A: No. Oil seals are single-use components and should be replaced once removed to ensure proper sealing.
