TC Oil Seal Lipped Rotary Shaft Seal — Precise Fit for ID 8mm–30mm Shafts

When a worn or leaking shaft seal turns a routine service into an oil-soaked headache, having the right TC oil seal on hand makes all the difference. Mechanics, fleet technicians, and serious DIYers working on automotive camshafts, gearboxes, differentials, and small industrial machinery need a seal that fits precisely, installs cleanly, and holds up under continuous rotation — not a generic part that leaks within a season.

Each seal in this listing is a TC-type double-lipped rotary shaft oil seal with a metal outer casing and a flexible elastomer lip. Inner diameters (ID) range from 8mm (≈5/16") to 30mm (≈1-3/16"), outer diameters (OD) from 17mm (≈11/16") to 72mm (≈2-13/16"), and housing heights (H) of 5mm, 7mm, 8mm, 10mm, or 12mm. Available in single-piece (1 Pcs) or value packs (5 Pcs). Select your exact ID × OD and height from the variant dropdowns above.

Typical use cases include replacing camshaft front and rear seals on passenger cars and light trucks, sealing gearbox input shafts on motorcycles and ATVs, and servicing pump shafts on agricultural and construction equipment — anywhere a metric rotary shaft seal is specified.

🔵 Compatibility: Fits metric shaft and bore applications per ISO 6194 / DIN 3760. Verify your shaft ID, housing bore OD, and housing depth (H) before ordering. Not for high-pressure hydraulic circuits.

✅ Key Features of These TC Oil Seal Lipped Rotary Shaft Seals

🔩Double-Lip TC Design — The outer metal casing provides a firm press-fit into the housing bore, while the inner dust lip and primary sealing lip work together to retain lubricant and exclude contaminants on rotating shafts.
📐Wide Metric Size Range — ID 8–30mm paired with OD options up to 72mm and five height choices (5, 7, 8, 10, 12mm) cover the majority of light-vehicle camshaft seals, gearbox shaft seals, and small-machinery rotary shaft seals in a single listing.
🛡️Elastomer Sealing Lip — The flexible lip maintains consistent radial contact force against the shaft surface, generally tolerating minor shaft runout and surface finish variations typical of production machining.
⚙️Metal Outer Shell — The rigid outer casing resists distortion during press-fit installation and maintains housing bore concentricity, reducing the risk of seal walk-out under vibration or thermal cycling.
🔄Suitable for Continuous Rotation — Engineered for dynamic rotary shaft sealing applications, making these seals a direct-fit replacement for OEM-spec metric shaft seals on automotive and industrial equipment.
📦Single or 5-Pack Quantity Options — Order one seal for a single repair or choose the 5 Pcs pack for workshop stock and fleet maintenance — both ship from our US warehouse for fast domestic delivery.

⚠️ Sizing Note: Always measure your shaft ID, housing bore OD, and housing depth (H) with calipers before ordering. A seal that is even 0.5mm undersized on the OD will not seal the housing bore correctly.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

Measure the shaft inner diameter (ID), the bore outer diameter (OD), and the housing depth (H) with calipers. Match all three dimensions to the variant you select. For example, a shaft of 20mm with a 40mm bore and 7mm housing depth needs the 20mm × 40mm / H7mm variant. When in doubt, round up to the nearest available OD to ensure a snug housing fit.

What load or pressure can these TC oil seals handle?

TC-type lipped oil seals are generally rated for low-to-medium pressure applications — typically up to 0.3 bar (4.4 psi) of continuous lip pressure. They are designed for dynamic rotary shaft sealing rather than high-pressure hydraulic containment. Contact us to confirm suitability for your specific application.

Can these oil seals be used outdoors or in wet environments?

TC oil seals with a nitrile (NBR) lip are generally suitable for outdoor and wet environments, resisting water, light oils, and common greases. For prolonged UV exposure or salt-spray conditions, a fluoroelastomer (FKM) seal is typically recommended. Check the variant description or contact us to confirm the lip material before outdoor installation.

What shaft and bore standards are these seals compatible with?

These TC oil seals follow metric dimensional standards (ISO 6194 / DIN 3760) and are compatible with metric shafts and bores. They are commonly used in automotive, agricultural, and industrial equipment that specifies metric shaft seals. Imperial-shaft equipment may require an adapter or a different seal series — contact us to confirm.

How do I install a TC rotary shaft oil seal correctly?

Clean the housing bore and shaft. Lightly lubricate the seal lip with the fluid it will retain. Press the seal squarely into the bore using a seal driver or a flat block — never hammer directly on the seal face. The metal OD should be flush with or slightly below the housing face. Avoid nicking the lip on keyways or splines during installation.

Which applications are these TC oil seals typically used in?

TC lipped rotary shaft seals are commonly used in automotive camshafts, crankshafts, gearbox input/output shafts, differential pinion shafts, water pumps, hydraulic cylinders, and general industrial rotating equipment. The wide size range (ID 8–30mm) covers most light-vehicle and small-machinery shaft diameters.

What is the difference between ordering 1 Pcs vs 5 Pcs?

Both options ship the same seal. The 5 Pcs quantity option provides a per-unit discount and is ideal for workshop stock, fleet maintenance, or when replacing multiple seals of the same size. The 1 Pcs option is best for a single repair or to test fitment before ordering in bulk.
