Rotary Shaft Seal 70x100x10 NBR TC (Double Lip)

Applications

This rotary shaft seal 70 x 100 x 10 mm in NBR with a TC (double-lip) design is engineered for demanding industrial applications where reliable oil retention and contaminant exclusion are critical. Use cases include hydraulic motors, gearboxes, engine crankshafts, drive units and other rotating shafts in heavy-duty machinery and automotive sectors. As a technical seal and shaft sealing ring, this oil seal ensures high durability and robust performance in industrial sealing and rotary seal scenarios.

Advantages

• Double-lip oil seal (TC) construction: The primary sealing lip delivers excellent fluid retention while the secondary lip guards against ingress of dirt and dust—ideal for environments requiring enhanced contamination resistance.

• Material: NBR (nitrile butadiene rubber): Offers strong resistance to oils, greases and common industrial fluids, ensuring long service life of the seal and minimized maintenance in applications.

• Optimised dimensions (70 x 100 x 10 mm): Standard size for many shaft and housing configurations, simplifying replacement, stock-keeping and installation in B2B operations.

• Industrial-grade sealing solution: Suitable for technical sealing in industrial applications, hydraulic and automotive seals, providing dependable performance under dynamic conditions, with low friction and high durability.

• Reduced downtime and maintenance costs: By selecting a high-quality rotary shaft seal specifically designed for double-lip sealing, you support equipment reliability and optimize lifecycle cost for your machinery.

FAQ

Q1: What is the difference between a single-lip and double-lip oil seal (TC) design?
A1: A single-lip seal has one sealing lip that retains fluid; a double-lip (TC) seal adds a secondary lip that protects against contamination (dust, debris) and enhances sealing reliability—particularly useful in heavy-duty or dirty environments.

Q2: Why choose NBR material for this shaft seal?
A2: NBR (nitrile rubber) offers excellent compatibility with oils, greases and many industrial fluids and is suitable for typical operating temperatures in machinery. It is a cost-effective material for applications where fluid resistance and durability are required.

Q3: How to select the correct size shaft seal for my equipment?
A3: Measure shaft diameter, housing bore (outer diameter), and width of the sealing groove. For this product, the dimensions are ID 70 mm, OD 100 mm and width 10 mm. Correct sizing and installation ensure optimal sealing performance and longer service life.

Q4: In what industrial applications is this seal best suited?
A4: This rotary shaft seal is designed for industrial applications including gearboxes, hydraulic motors, engine drive systems, industrial pumps and other rotating shaft assemblies requiring high-durability oil retention and contaminant exclusion.
