NBR TC Double Lip Oil Seal — Reliable Shaft Sealing for Rotating Equipment

Leaking grease, contaminated bearings, and premature shaft wear are costly problems for mechanics, equipment operators, and DIY rebuilders alike. Whether you're rebuilding a gearbox, servicing agricultural machinery, or replacing worn seals on industrial rotating shafts, getting the right TC oil seal makes the difference between a lasting repair and a repeat failure.

Each seal in this listing is a TC-type (double lip) skeleton oil seal made from NBR (Nitrile Butadiene Rubber) with a steel skeleton insert for dimensional stability. Available in a wide range of metric sizes with an inner diameter (I.D.) from 45mm (≈1.77") to 62mm (≈2.44"), outer diameter (O.D.) from 60mm (≈2.36") to 100mm (≈3.94"), and heights of 7mm, 8mm, 10mm, or 12mm — covering the most common shaft and housing combinations in this bore range. Order as a single piece, a pack of 5, or a pack of 10 for workshop stock.

These NBR TC double lip oil seals are well suited for gearbox shaft seals on agricultural and construction equipment, axle and differential seals on light vehicles and trailers, and pump shaft sealing in irrigation and industrial fluid-handling systems where dust exclusion and grease retention are both required.

🔵 Compatibility: Fits standard metric shafts and housings per ISO/DIN tolerances. Match seal I.D. to shaft diameter, O.D. to housing bore, and height to groove depth. See variant selector for all available size combinations.

✅ Key Features of These NBR TC Double Lip Oil Seals

  • 🔒 Double Lip TC Design — The primary lip retains lubricant while the secondary dust lip blocks dirt, moisture, and debris from reaching the bearing — a key advantage over single-lip seals in contaminated environments.
  • 🧱 Steel Skeleton Insert — An internal metal skeleton maintains the seal's circular shape during installation and under operating loads, preventing distortion and ensuring consistent contact with the shaft and housing bore.
  • 🛢️ NBR Rubber Compound — Nitrile Butadiene Rubber provides solid resistance to mineral oils, greases, gear lubricants, and water — making these rotation shaft seal rings a practical choice for most standard lubrication systems.
  • 📐 Wide Metric Size Range — I.D. from 45mm to 62mm, O.D. from 60mm to 100mm, and heights of 7–12mm cover a broad range of gearbox, axle, and pump shaft sealing applications without needing custom parts.
  • 📦 Flexible Pack Quantities — Available as 1 pc, 5 pcs, or 10 pcs per order, so you can buy a single replacement seal or stock up for workshop use without overpaying for quantity you don't need.
  • ⚙️ Drop-In Replacement Fit — Dimensioned to standard metric tolerances, these TC skeleton oil seals are designed to install into existing housings without machining or modification in most standard applications.

❓ Frequently Asked Questions

How do I choose the right oil seal size?

Match the seal's I.D. to your shaft diameter and the O.D. to your housing bore. The height (width) should fit within the housing groove depth. For example, a shaft of 45mm (≈1.77") typically uses a seal with a 45mm I.D. Always verify all three dimensions before ordering — I.D., O.D., and height must all match.

What load or pressure can these seals handle?

TC-type oil seals are generally designed for low-to-medium pressure applications. They are typically rated for shaft surface speeds up to around 4–8 m/s and pressures up to approximately 0.05 MPa. For high-pressure or high-speed applications, consult your equipment specifications and consider a seal rated for those conditions.

Are these seals suitable for outdoor or wet environments?

NBR offers good resistance to water, grease, and common mineral oils, making it generally suitable for outdoor and wet conditions. However, NBR is not recommended for prolonged exposure to ozone, strong UV, or certain synthetic fluids such as phosphate ester hydraulic fluids. For highly aggressive chemical environments, FKM (Viton) seals are typically a better choice.

What shaft or housing standards are these compatible with?

These TC skeleton oil seals follow standard metric dimensions and are generally compatible with ISO and DIN metric shaft and housing tolerances. They are commonly used as direct replacements in gearboxes, axles, and pumps that specify metric TC seals. Always verify the I.D., O.D., and height against your equipment's service manual before installation.

Why choose a double lip (TC) seal over a single lip seal?

TC-type seals feature a double lip design: the primary lip retains lubricant inside the housing while the secondary (dust) lip excludes contaminants from outside. In most cases, this makes TC seals a better choice than single-lip seals in environments with dust, dirt, water spray, or moisture ingress — which is common in agricultural, construction, and outdoor equipment.

Can I use these seals with gear oil or hydraulic fluid?

NBR is generally compatible with mineral-based gear oils, hydraulic fluids, and greases. It is not recommended for use with phosphate ester hydraulic fluids, aromatic fuels, or ketones. When in doubt, confirm fluid compatibility with an NBR chemical resistance chart or contact us to confirm before ordering.

What is the difference between the 8mm, 10mm, and 12mm height options?

The height (also called width or cross-section) must match your housing groove depth. A taller seal (12mm) provides more sealing surface area but requires a deeper housing groove. A shorter seal (7mm or 8mm) fits shallower grooves. Always measure your housing groove depth before selecting the height — using the wrong height will prevent the seal from seating correctly even if the I.D. and O.D. are correct.
