Rotary Shaft Seal 95x120x15 NBR TC

Applications

The Rotary Shaft Seal 95x120x15 NBR TC is designed for sealing rotating shafts in mechanical assemblies where oil, grease, or lubricant retention is essential. Commonly used in industrial machinery, gearboxes, pumps, electric motors, hydraulic equipment, and automotive powertrain systems. The TC construction features a primary sealing lip combined with a secondary dust lip to prevent contamination from particles and moisture.

Advantages

Manufactured from high-quality NBR (Nitrile Rubber), this oil seal provides reliable resistance to mineral oils, lubricants, and standard hydraulic fluids. The metal outer case ensures secure press-fit installation and dimensional stability during operation. The single-lip TC design supports effective sealing performance under moderate speeds and pressures, delivering high durability and consistent sealing over extended service intervals.

Technical Information

• Size: 95x120x15 mm
• Type: TC (primary sealing lip + dust lip)
• Material: NBR (Nitrile Rubber)
• Outer Structure: Metal reinforcement
• Operating environment: oils, lubricants, greases
The seal ensures controlled lubricant retention and prevents leakage, reducing wear of contacting surfaces and maintaining efficiency of the shaft system.

Main Description

This rotary shaft seal 95x120x15 NBR TC is a technical sealing component designed to maintain lubrication integrity and protect rotating machinery from contaminants. The seal’s NBR elastomer formulation provides robust resistance to oils and greases commonly encountered in industrial and automotive environments, making it suitable for gearboxes, transmissions, motor drives, and hydraulic systems. The reinforced metal case ensures stable housing alignment, preventing seal deformation during installation and operation.
The TC profile integrates a secondary dust lip, improving protection against fine contaminants and extending the service span of adjacent bearings and shaft surfaces. The seal’s geometry delivers reliable sealing performance at moderate rotational speeds and temperatures typical of industrial equipment and engines. This oil seal is commonly required during preventive maintenance, overhaul, or unit replacement to ensure leak-free operation and optimal system lifespan.

FAQ

Q1: What is the difference between TC and SC oil seals?
TC has a double-function profile: sealing lip + dust lip. SC is a single-lip variant without an integrated dust barrier.
Q2: Is NBR suitable for high temperatures?
NBR performs well in typical oil-lubricated systems but for continuous high-temperature operation, FKM/FPM seals may be recommended.
Q3: How to select the correct shaft seal size?
Match the seal inner diameter to the shaft and the outer diameter to the housing bore, ensuring correct width and profile.
Q4: Can this seal be used in hydraulic pumps?
Yes, provided operating conditions fall within standard NBR temperature and speed ranges.
