Rotary Shaft Seals
KAFLON provides a comprehensive range of rotary shaft seals, engineered to prevent leakage, protect systems from contamination, and ensure optimal sealing performance in rotating equipment. Our rotary seals are designed to meet the demanding needs of industries such as hydraulics, automotive, industrial machinery, and fluid power systems.
We specialize in oil seals, rotary PTFE lip seals, and spring-energized seals, offering solutions tailored to specific applications that require high durability, resistance to wear, and the ability to function under extreme temperatures, pressures, and dynamic conditions.
KAFLON offers a wide range of elastomer and high-performance materials for rotary shaft seals, ensuring compatibility with diverse operating conditions.
Oil Seals (Elastomer Rotary Shaft Seals)
NBR (Nitrile Butadiene Rubber) – Cost-effective, good resistance to oils and lubricants
FKM (Fluorocarbon Rubber) – High resistance to heat, oils, and aggressive chemicals
HNBR (Hydrogenated Nitrile Rubber) – Enhanced wear resistance and mechanical strength
Rotary PTFE Lip Seals
PTFE – Low friction, excellent resistance to chemicals and high temperatures, suitable for high-speed applications and dry running conditions
Glass-filled PTFE – Enhanced strength and stability under extreme conditions
Rotary Spring-Energized Seals
Spring-energized PTFE seals – Ideal for high-pressure, high-speed environments where consistent sealing force is required, even under thermal expansion or wear.
Material selection depends on the application requirements such as shaft speed, pressure, temperature, media compatibility, and service life.
KAFLON rotary shaft seals are widely used in various industrial sectors, including:
Hydraulic & Fluid Power Systems
Automotive & Transportation
Industrial Machinery & Equipment
Construction & Mining Equipment
Heavy-duty machinery and drive systems
Seals for equipment operating in abrasive and high-load environments
Rotary Shaft Seals vs Other Dynamic Seals
| Feature | Rotary Shaft Seals | Mechanical Face Seals | O-Rings |
|---|---|---|---|
| Motion Type | Continuous rotation | Rotation / axial | Limited dynamic |
| Friction | Low | Moderate | High |
| Speed Capability | High | Moderate | Low |
| Cost Efficiency | High | Lower | High |
| Typical Use | Shafts & housings | Heavy-duty systems | Static or low-speed |
