Applications and Function
The Rotary Shaft Seal 40x54x7 NBR TC is a double lip oil seal designed to protect shafts, bearings, and housings from lubricant leakage and the ingress of dust, dirt, and moisture. Commonly searched terms include “40x54x7 oil seal”, “shaft seal 40x54x7 NBR”, “double lip TC seal”, and “rotary shaft seal 40x54x7”.
Manufactured from high-grade NBR (nitrile rubber), this rotary oil seal combines flexibility and resilience with resistance to oils, lubricants, and moderate mechanical wear. The TC profile (rubber-coated steel case + spring-loaded sealing lip) ensures tight contact with the shaft surface, maintaining an effective seal even under continuous dynamic conditions.
This double lip design enhances protection, making it ideal for gearboxes, pumps, engines, electric motors, agricultural equipment, and industrial machinery.
Advantages and Material Features
-
Durable NBR elastomer: excellent resistance to oils, greases, and hydraulic fluids.
-
Double lip design (TC type): the primary lip retains oil, while the secondary lip protects against dust and external contaminants.
-
Temperature range: typically from -30 °C to +100 °C (briefly up to +120 °C), ensuring reliable sealing in varied environments.
-
Steel reinforcement: provides structural stability and precise installation in housings.
-
Spring-loaded sealing edge: maintains consistent radial pressure for long-term performance.
-
Versatile industrial use: suitable for both static and rotary shaft sealing in medium-speed applications.
Thanks to its proven performance and universal dimensions, the 40x54x7 NBR TC oil seal is widely used across mechanical, hydraulic, and automotive systems requiring high durability and oil resistance.

FAQ - Frequently Asked Questions
Q: What is the difference between a single lip and a double lip oil seal?
A: A single lip seal prevents oil leakage, while a double lip seal (TC) has an extra dust lip that blocks dirt and moisture, extending service life.
Q: Why is NBR commonly used for rotary shaft seals?
A: NBR offers an excellent balance of oil resistance, flexibility, and affordability, making it ideal for most industrial and automotive sealing applications.
Q: Can this oil seal operate under high pressure?
A: The NBR TC oil seal is designed for standard pressure conditions. For higher pressure applications, specialized hydraulic seals are recommended.
Q: What’s the temperature range for this NBR TC seal?
A: It performs reliably from -30 °C to +100 °C, with short-term peaks up to +120 °C.
Q: Is it suitable for both static and rotary use?
A: Yes, it can be used in both configurations, depending on system design and lubrication.
