35x62x10 AO/TC FPM FKM Viton Rotary Shaft Oil Seal Double Lip

What Is the 35x62x10 AO/TC FPM FKM Viton Oil Seal?

The 35x62x10 AO/TC FPM FKM Viton Rotary Shaft Oil Seal is a high-performance radial shaft seal designed for demanding operating conditions where conventional NBR seals may not provide sufficient thermal or chemical resistance. Manufactured from FPM (FKM Fluorocarbon Rubber), commonly known as Viton®, it offers outstanding resistance to high temperatures, mineral and synthetic oils, fuels and a wide range of aggressive industrial chemicals.

The AO/TC design incorporates two sealing lips. The primary spring-loaded lip retains lubricant inside the system, while the secondary dust lip protects against dirt, dust and moisture entering the equipment. With dimensions of 35 mm inner diameter, 62 mm outer diameter and 10 mm width, this oil seal is widely used in industrial machinery, pumps, gearboxes, compressors, hydraulic equipment and OEM manufacturing.

Design and Construction

The AO/TC profile is specifically developed for applications requiring enhanced environmental protection.

Key construction features include:

• AO/TC double-lip design
• Primary spring-loaded sealing lip
• Secondary dust protection lip
• FPM (FKM Viton®) sealing material
• Precision sealing edge
• Excellent chemical resistance
• Long-term sealing reliability

The additional dust lip significantly reduces contamination, helping extend the service life of bearings, shafts and lubricants.

How Does an AO/TC Oil Seal Work?

A rotary shaft oil seal creates a dynamic seal between a rotating shaft and a stationary housing.

The primary sealing lip:

• Retains lubricating oil
• Maintains internal sealing pressure
• Reduces lubricant leakage

The secondary dust lip:

• Prevents dust ingress
• Protects against dirt
• Reduces moisture contamination
• Extends bearing service life

This dual-lip configuration is particularly effective in dusty, dirty and demanding industrial environments.

Why Choose FPM FKM Viton®?

FPM is one of the highest-performance sealing materials used in industrial engineering.

Its advantages include:

• Excellent high-temperature resistance
• Outstanding resistance to mineral and synthetic oils
• Excellent fuel compatibility
• Superior chemical resistance
• Excellent ozone and UV resistance
• Outstanding ageing resistance
• Low compression set
• Long operational service life

These characteristics make FPM the preferred sealing material for demanding industrial and automotive applications.

Selecting the Correct Oil Seal

When choosing a rotary shaft seal, engineers should consider:

• Shaft diameter
• Housing bore diameter
• Seal width
• Operating temperature
• Shaft speed
• Lubricant type
• Working environment
• Chemical compatibility

Selecting the appropriate sealing material is particularly important in high-temperature and chemically aggressive applications.

Installation Recommendations

For maximum sealing performance:

• Clean all mounting surfaces.
• Inspect the shaft sealing area.
• Lubricate the sealing lip before installation.
• Use proper installation tools.
• Install the seal squarely into the housing.
• Avoid damaging either sealing lip during assembly.

Proper installation significantly extends seal service life.

Common Causes of Oil Seal Failure

Typical causes include:

• Incorrect material selection
• Installation damage
• Excessive shaft runout
• Contamination
• Dry running
• High operating temperatures
• Insufficient lubrication
• Worn shaft surfaces

Preventive maintenance and proper material selection greatly improve seal reliability.

Frequently Asked Questions (FAQ)

What does AO/TC mean?

AO/TC identifies a double-lip rotary shaft oil seal with a primary spring-loaded sealing lip and a secondary dust protection lip.

Are FPM and FKM the same material?

Yes. FPM and FKM are internationally recognized designations for fluorocarbon rubber. Viton® is the best-known commercial trade name.

Is this oil seal resistant to fuel?

Yes. FPM provides excellent resistance to gasoline, diesel fuel, synthetic oils and many aggressive industrial chemicals.

Can it operate at high temperatures?

Yes. FPM is specifically designed for elevated operating temperatures where conventional NBR seals may no longer perform reliably.

Why choose a double-lip oil seal?

The additional dust lip provides extra protection against contamination, helping extend the service life of bearings, shafts and lubricants.

Where is this oil seal commonly used?

It is widely installed in industrial machinery, pumps, compressors, hydraulic equipment, automotive systems, OEM production and industrial maintenance applications.
