Oil Seal 32x52x5 NBR AO/TC - Rotary Shaft Seal

Applications

This Oil Seal 32x52x5 NBR AO/TC is designed for sealing rotating shafts in mechanical assemblies where protection against oil leakage, grease displacement, and external contamination is required. It is commonly used in industrial gearboxes, small engines, pumps, electric motors, power transmission equipment, agricultural machinery, and automotive systems. The AO/TC double-lip design ensures effective sealing under dynamic conditions, maintaining lubrication inside while preventing dust and moisture from entering the system.

Advantages and Performance

Manufactured from NBR (nitrile butadiene rubber), this rotary oil seal offers excellent resistance to mineral oils, hydraulic fluids, fuels, and lubricants. The material retains flexibility under continuous shaft rotation and temperature variations. The double-lip (TC) structure improves sealing stability by providing a primary lip for fluid retention and a secondary wiper lip for dirt exclusion, ensuring extended service life. This design supports high durability, stable operation, and reduced downtime in mechanical systems.

Main Description

The Oil Seal 32x52x5 NBR AO/TC is a high-performance rotary shaft seal engineered for demanding industrial and automotive applications. Its NBR construction ensures superior resistance to oils, fuels, and lubricants, making it suitable for environments with constant exposure to petroleum-based fluids. The double lip oil seal (TC type) with an integrated garter spring provides consistent contact pressure on the shaft surface, enhancing sealing reliability and reducing leakage risk during continuous rotation.

This shaft sealing ring effectively prevents contamination ingress caused by dust, moisture, and particles, supporting the long-term performance of gears, pumps, motors, and power transmission components. The compact 5 mm width makes it ideal for equipment where installation space is limited, while the robust sealing geometry ensures stability even at variable shaft speeds.

Designed for engineers, maintenance professionals, and industrial procurement teams, this technical seal combines durability, cost-effectiveness, and operational reliability. Whether used in manufacturing plants, vehicle servicing, or machinery repair, it delivers consistent performance and extended service intervals.

FAQ

1. What is the difference between single lip and double lip oil seals?
A single lip seal retains fluid only, while a double lip (TC) seal includes an additional dust lip to prevent external contamination.

2. What temperatures is NBR suitable for?
NBR typically operates reliably between -30°C and +100°C, depending on specific fluid contact conditions.

3. How do I select the correct shaft seal size?
Match the inner diameter to the shaft, the outer diameter to the housing, and the width to available installation space.

4. When should an oil seal be replaced?
Whenever leakage, visible wear on the sealing lip, or shaft scoring is observed during inspection.
