TC Oil Seal ID 100–115mm — Stop Leaks on Rotary Shafts Before They Become Costly Repairs

Mechanics, equipment operators, and maintenance professionals know the frustration: a weeping gearbox seal that turns a routine service into a full teardown. Whether you're rebuilding an agricultural gearbox, servicing an industrial reducer, or replacing a worn pump shaft seal, finding the exact TC oil seal size — inner diameter, outer diameter, and thickness — in one place saves hours of sourcing time.

Each seal in this listing is a TC-type skeleton oil seal constructed with an NBR (nitrile rubber) sealing element bonded to a steel skeleton (metal case). The dual-lip design features a primary sealing lip that retains lubricant and a secondary dust lip that blocks contaminants. Available inner diameters span 100mm to 115mm (≈3.94" to 4.53"); outer diameters range from 115mm to 215mm (≈4.53" to 8.46"); thickness options run from 7mm to 16mm (≈0.28" to 0.63"). Select your exact ID × OD × Thickness from the variant dropdown — sold individually (1 PCS per order).

Typical applications include agricultural tractor gearboxes and PTO shafts, industrial gearbox output shafts, centrifugal pump housings, and heavy-equipment axle seals — anywhere a rotary shaft NBR dual lip seal ring is needed to contain petroleum-based lubricants under moderate speed and pressure.

🔵 Compatibility: Fits standard metric bore housings. Verify your shaft ID, housing bore OD, and housing depth (thickness) before ordering. Dimensions listed as ID × OD × Thickness in millimeters.

✅ Key Features of These TC Skeleton Oil Seals

  • 🔩 Dual-Lip TC Design — The primary lip seals lubricant in; the secondary dust lip keeps abrasive particles and moisture out, extending bearing and gear life in dirty environments.
  • 🛡️ NBR Nitrile Rubber Construction — Resists petroleum-based oils, gear lubricants, hydraulic fluids, and greases across a typical service range of −40°F to +250°F (−40°C to +120°C).
  • ⚙️ Steel Skeleton Reinforcement — The metal case maintains dimensional stability during press-fit installation and prevents the seal from distorting under housing clamping forces.
  • 📐 160+ Size Variants in One Listing — Inner diameters from 100mm to 115mm paired with multiple OD and thickness combinations, covering a wide range of rotary shaft seal ring replacements without hunting across multiple SKUs.
  • 🔄 Drop-In Replacement Geometry — Metric dimensions follow standard DIN 3760 / ISO 6194 envelope sizing, making these seals direct replacements for OEM parts in agricultural gearboxes, industrial reducers, and pump housings.
  • 🚚 Ships from US Warehouse — Stocked domestically for fast delivery; no extended international lead times when you need a rotary shaft NBR dual lip seal ring quickly.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

Measure three dimensions: the shaft diameter (= seal ID), the housing bore diameter (= seal OD), and the housing depth (= seal thickness). Match all three to the variant listed as ID × OD × Thickness. For example, a 110×140×12mm seal fits a 110mm (≈4.33") shaft, 140mm (≈5.51") bore, and 12mm (≈0.47") housing depth. When in doubt, measure the old seal with calipers before ordering.

What does "TC" mean on an oil seal?

TC designates a double-lip radial shaft seal with a metal skeleton (case). The primary lip retains lubricant inside the housing; the secondary lip generally acts as a dust excluder to prevent contaminants from reaching the primary lip and the bearing. This dual-lip design is the most common configuration for gearboxes, pumps, and axles.

What shaft speed and pressure can these seals handle?

NBR TC oil seals typically handle shaft surface speeds up to approximately 4–6 m/s and low differential pressures (generally under 0.05 MPa / 7 psi). Exceeding these limits can cause lip wear, heat buildup, and premature leakage. If your application involves higher speeds or pressures, contact us to confirm suitability before ordering.

Are these seals suitable for outdoor or wet environments?

NBR offers good resistance to petroleum-based oils, greases, and mild water splash. The secondary dust lip provides additional protection against dirt and moisture ingress. For prolonged outdoor UV exposure, saltwater immersion, or aggressive chemical environments, a FKM (Viton) seal is generally recommended. Contact us to confirm compatibility with your specific conditions.

What fluids are compatible with NBR oil seals?

NBR is compatible with mineral oils, petroleum-based hydraulic fluids, gear oils, greases, and diesel fuel. It is generally not recommended for use with ketones (MEK, acetone), esters, aromatic solvents, or brake fluids. If you are sealing a non-petroleum fluid, contact us to confirm material compatibility.

What is the operating temperature range?

NBR TC oil seals typically operate between −40°F and +250°F (−40°C to +120°C). Continuous operation near the upper limit may accelerate rubber hardening and lip wear. For high-temperature applications above 250°F, a silicone or FKM seal is generally more appropriate.

How do I install a TC skeleton oil seal correctly?

1. Clean the housing bore and shaft journal thoroughly. 2. Lightly coat the seal lip with the lubricant being sealed. 3. Press the seal squarely into the bore using a seal driver or flat plate sized to the OD — never strike the seal face directly with a hammer. 4. Seat the seal until the metal case is flush with or slightly below the housing face. 5. Check that the shaft passes through the lip without cutting or rolling the rubber.

Can I use these seals on agricultural or industrial equipment?

Yes. TC skeleton oil seals in the 100–115mm ID range are commonly used in agricultural tractor gearboxes, PTO shafts, industrial speed reducers, centrifugal pump housings, and heavy-equipment axle ends. Confirm the ID, OD, and thickness match your housing dimensions before ordering. If you need help cross-referencing an OEM part number, contact us.
