Rotary Shaft Seal 174x190x5 NBR TC Double Lip Oil Seal

Reliable Sealing for Demanding Industrial and Automotive Applications

The Rotary Shaft Seal 174x190x5 NBR TC Double Lip Oil Seal is an advanced shaft sealing ring designed to protect rotating components from oil leakage and external contamination. Manufactured from high-quality NBR (nitrile butadiene rubber), this double lip rotary seal provides excellent resistance to oils, lubricants, fuels, and other aggressive media commonly found in industrial and automotive environments.

Its TC (double lip with spring) configuration ensures enhanced sealing efficiency. The primary lip maintains oil retention, while the secondary dust lip prevents the ingress of dirt, dust, and moisture. This makes the seal ideal for high-speed shafts, transmissions, gearboxes, and hydraulic systems, where reliability and long service life are essential.

Advantages and Technical Features

The 174x190x5 NBR TC oil seal combines robust design with precision engineering, ensuring dependable performance in heavy-duty environments.

Key advantages:

• 🔹 Material: NBR rubber - high flexibility and resistance to wear, oils, and greases.

• 🔹 Type: TC - double lip oil seal with reinforced metal case and spring-loaded sealing edge.

• 🔹 Dimensions: 174 mm (inner diameter) x 190 mm (outer diameter) x 5 mm (width).

• 🔹 Temperature range: -30°C to +100°C.

• 🔹 Features: Long service life, low friction, and high sealing reliability even under dynamic load.

Thanks to its durable construction and precise fit, this rotary oil seal ensures effective sealing in both industrial machinery and automotive powertrain systems. It minimizes lubricant loss, reduces wear on rotating components, and helps extend maintenance intervals.

Typical Applications

The 174x190x5 NBR TC double lip seal is widely used across multiple industries:

• ⚙️ Automotive sector: Crankshafts, camshafts, axle assemblies, and gearboxes.

• 🏭 Industrial applications: Electric motors, pumps, compressors, and reduction gears.

• 🚜 Agricultural and heavy machinery: Hydraulic drives, power transmission systems, and differential shafts.

This makes it an ideal sealing solution for OEM manufacturers, service workshops, and industrial maintenance providers seeking dependable, cost-effective sealing components.

FAQ

1. What is a TC-type oil seal?
A TC-type seal is a double lip rotary shaft seal with a metal outer shell and a tension spring on the primary lip. It offers superior sealing performance and protection against external contaminants.

2. What are the advantages of NBR material?
NBR (nitrile rubber) provides excellent resistance to oils, fuels, and greases, as well as flexibility and mechanical strength in a wide temperature range.

3. How is a double lip oil seal different from a single lip seal?
A double lip seal has an extra dust lip that blocks contaminants, extending the lifespan of the seal and protecting the system from wear.

4. Can this seal be used in high-speed applications?
Yes, its low-friction design and reinforced structure make it suitable for high-speed rotating shafts in both industrial and automotive systems.

5. How to select the correct rotary shaft seal size?
Measure the shaft diameter, housing bore, and width precisely. The 174x190x5 NBR TC oil seal fits shafts of 174 mm with a 190 mm bore and 5 mm width.
