What material are these oil seals made from?

These TC oil seals are typically constructed with a nitrile rubber (NBR) sealing lip bonded to a steel outer case. NBR is generally compatible with petroleum-based oils, gear oils, and common automotive fluids. For high-temperature or aggressive chemical environments, confirm compatibility before installation.

Can these seals be used outdoors or in wet environments?

The steel outer case can be susceptible to surface rust if exposed to standing water or salt spray over extended periods. For outdoor or marine applications, applying a thin film of grease to the outer case during installation is generally recommended. The NBR lip itself is resistant to water and most common lubricants.

Are these seals compatible with metric shafts and housings?

Yes. All dimensions listed (ID, OD, Height) follow metric standards in millimeters. They are compatible with metric shafts and housings conforming to ISO 6194 / DIN 3760 standards. For inch-size shafts, convert your measurements to mm and select the closest matching variant.

What vehicles and equipment are these oil seals used on?

TC oil seals in this size range are commonly used on car camshafts, crankshafts, gearbox input/output shafts, differential pinion shafts, power steering pumps, agricultural equipment, and general industrial rotating machinery. Always verify the exact ID×OD×H dimensions match your application.

TC Oil Seal Lipped Rotary Shaft Sealing Ring — Stop Leaks at the Source

A leaking camshaft or gearbox seal is one of those problems that starts small and turns expensive fast. Whether you're rebuilding an engine, replacing a worn differential seal, or maintaining industrial rotating equipment, finding the exact ID×OD×height combination you need shouldn't require a trip to a specialty supplier. These TC FB TG4 lipped rotary shaft oil seals cover inner diameters from 60mm (≈2.36") to 400mm (≈15.75"), giving mechanics, engineers, and serious DIYers a single source for a wide range of shaft sealing needs.

Each seal is a TC (double-lip) design with a steel-reinforced outer case and a nitrile rubber (NBR) sealing lip. Variants are available in three dimensions: Inner Diameter (ID), Outer Diameter (OD), and Height (H). ID ranges from 60mm to 400mm, OD from 80mm to 440mm, and height from 8mm to 20mm — all in metric millimeters. Sold individually (1 Pcs) or in value packs (5 Pcs) to suit single repairs or workshop stock.

Typical applications include automotive camshaft front and rear seals, crankshaft seals, manual gearbox input shaft seals, differential pinion seals, agricultural PTO shaft seals, and general industrial rotary shaft sealing where a metric TC-type seal is specified. The double-lip construction makes these a go-to choice when searching for a double lip rotary shaft oil seal or a metric TC oil seal for camshaft.

ℹ️ Compatibility Notice: Always verify all three dimensions — Inner Diameter (ID), Outer Diameter (OD), and Height (H) — against your shaft and housing before ordering. Dimensions are in millimeters. Select your exact size from the variant dropdowns above.

✅ Key Features of These TC Oil Seals

🔒Double-Lip TC Design — The primary sealing lip retains lubricant while the secondary dust lip blocks contaminants, making this a reliable double lip shaft seal for both oil retention and ingress protection.
🔩Steel-Reinforced Outer Case — The rigid steel shell provides a firm press-fit into the housing bore, maintaining concentricity and resisting distortion during installation and operation.
🛢️NBR Sealing Lip — Nitrile rubber (NBR) offers broad compatibility with petroleum-based engine oils, gear oils, and common automotive fluids — a standard material for automotive rotary shaft seals.
📐Wide Size Range (60–400mm ID) — Over 100 ID×OD×H combinations in one listing, covering small camshaft seals up to large industrial shaft seals without needing multiple suppliers.
📦Flexible Quantity Options — Available as a single piece (1 Pcs) for one-off repairs or a 5-piece pack for workshop stock, fleet maintenance, or production line use.
⚙️Metric Dimensions, ISO-Compatible — All sizes follow metric standards consistent with ISO 6194 / DIN 3760, making these seals straightforward to cross-reference against OEM part numbers and engineering drawings.

⚠️ Size Confirmation: If you are unsure of your seal dimensions, measure the shaft OD (= seal ID), the housing bore ID (= seal OD), and the groove depth (= seal height) with calipers before ordering. Incorrect sizing is the most common cause of seal failure.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

Measure three dimensions with calipers: (1) the shaft diameter — this becomes the seal's Inner Diameter (ID); (2) the housing bore diameter — this becomes the seal's Outer Diameter (OD); (3) the groove or housing depth — this becomes the seal's Height (H). For example, a 60mm shaft in an 80mm bore with an 8mm groove needs a 60×80×8mm seal (≈2.36"×3.15"×0.31"). Always confirm all three before ordering.

What does "TC" mean on an oil seal?

TC designates a double-lip oil seal. The primary lip faces inward to retain lubricant; the secondary lip faces outward to exclude dust and moisture. This is generally preferred over single-lip (SC) seals in automotive and industrial applications where both oil retention and contamination exclusion matter.

What material is the sealing lip made from, and what fluids is it compatible with?

The sealing lip is typically made from Nitrile Rubber (NBR), which is generally compatible with petroleum-based engine oils, gear oils, automatic transmission fluid (ATF), and water. NBR is not recommended for use with phosphate ester hydraulic fluids or highly aromatic fuels. For synthetic or specialty fluids, contact us to confirm compatibility before ordering.

Can these seals be used outdoors or in wet/corrosive environments?

The NBR lip is resistant to water and most common lubricants. The steel outer case can develop surface rust if exposed to standing water or salt spray over extended periods. For outdoor, marine, or high-humidity applications, applying a thin film of grease to the outer case during installation is generally recommended to help prevent corrosion at the housing interface.

What shaft speed and pressure can these TC oil seals handle?

TC-type rotary shaft seals are typically rated for shaft surface speeds up to approximately 4–8 m/s (depending on shaft finish and lubrication) and low-to-moderate pressure differentials (generally under 0.05 MPa / ~7 psi). For high-speed spindles or pressurized housings, contact us to confirm suitability for your specific application.

Are these seals compatible with metric shafts and ISO standards?

Yes. All dimensions (ID, OD, Height) are in millimeters and are consistent with ISO 6194 / DIN 3760 metric oil seal standards. They are designed for metric shafts and housings. If your application uses inch-size shafts, convert your measurements to millimeters (1 inch = 25.4mm) and select the closest matching variant, then verify the fit before final installation.

What vehicles and equipment are these oil seals commonly used on?

TC oil seals in this size range are commonly used on: car and truck camshaft seals, crankshaft front and rear seals, manual gearbox input/output shaft seals, differential pinion seals, power steering pump seals, agricultural tractor PTO shaft seals, and general industrial rotating machinery. Always verify the exact ID×OD×H dimensions match your application's specifications.
