Oil Seal 140x180x12 NBR TC

Industrial Applications & Use Cases

The oil seal 140x180x12 NBR TC is engineered for demanding industrial environments where reliable sealing of rotating shafts is critical. With an inner diameter of 140 mm, outer diameter of 180 mm and width of 12 mm, this rotary shaft seal is ideally suited for installation in bearing housings, bearing units or shaft assemblies. The “TC” classification indicates a double-lip oil seal design, providing enhanced performance against lubricant leakage and ingress of contaminants. Typical industrial applications include gearboxes, electric motors, pumps, drive units and automation systems where high durability, resistance to oils and grease, and minimal maintenance are key.

Key Advantages & Technical Features

• High durability: Made from NBR (nitrile-butadiene rubber), the seal offers strong resistance to mineral oils, greases and lubrication fluids common in industrial applications, supporting long service life in harsh conditions.

• Double-lip configuration (TC): The double lip ensures the primary lip retains the lubricant while the secondary lip acts as a barrier against dust, dirt and external contamination—ideal for rotary seal or shaft sealing ring usage in industrial settings.

• Standard dimensions (140x180x12 mm): These common dimensions enable quick identification, easy fitting into standard housings and compatibility with bearing units or obudowa łożyskowa assemblies.

• Versatile industrial sealing solution: This oil seal is suitable for a variety of industrial applications—engine seal tasks, hydraulic and automotive seals, technical seal uses—where robust rotary seal performance is required.

• B2B readiness: For procurement specialists, maintenance managers and engineers, this sealed component is stocked and ready to dispatch, supporting fast turnaround, minimal downtime and high operational availability.

FAQ

Q1: What is the difference between a single-lip and a double-lip oil seal?
A1: A single-lip oil seal features one sealing edge to retain lubricant, while a double-lip design (like TC) includes a second protective lip to guard against external contaminants. This makes the double-lip type better suited for industrial applications where dust, dirt or external exposure are factors.

Q2: Why is NBR material used for these seals and what are its benefits?
A2: NBR (nitrile-butadiene rubber) offers excellent resistance to mineral oils, greases and common lubricants, making it highly suitable for oil seals and rotary shaft seals in industrial settings. It combines durability, wear-resistance and compatibility with many media.

Q3: How should I select the correct oil seal size for my application?
A3: Determine the shaft diameter (inner diameter), the housing bore (outer diameter), and the available width/thickness of the seal. For this seal: 140 mm bore, 180 mm outer, 12 mm width. Also consider the seal design (double-lip vs single-lip), material compatibility (oil, grease, temperature) and the intended use (rotary vs stationary).

Q4: Is this oil seal suitable for hydraulic and automotive applications?
A4: Yes—this oil seal is designed for industrial rotary shaft sealing and can serve in hydraulic or automotive seals where the dimensions, material (NBR) and double-lip design align with the operating conditions. Confirm the specific application demands (speed, media, temperature) before selection.
