Rotary shaft seals are essential for preventing leaks and protecting rotating components in motors, pumps, and gearboxes. Choosing the right seal improves equipment efficiency and reduces failure risks.
What Is a Rotary Shaft Seal and How Does It Work?
A rotary shaft seal (oil seal) forms a barrier between a rotating shaft and the housing to retain lubrication and block contaminants.
Functions of Rotary Shaft Seals:
- Prevents lubrication loss
- Blocks dust, dirt, and moisture
- Extends equipment lifespan by minimizing wear

What Material Is Best for Rotary Shaft Seals?
Each material offers unique benefits:
| Material | Best For | Key Advantages |
|---|---|---|
| NBR | General use | Cost-effective, oil-resistant |
| FKM | High-temp & chemical | Heat/chemical resistance |
| PTFE | High-speed use | Low friction, durable |
Explore material comparisons.
What Factors Should You Consider Before Buying?
To choose the correct seal:
- Temperature range – Use FKM for high heat
- Rotational speed – PTFE suits high RPMs
- System pressure – Choose high-pressure-rated oil seals
