TC Double Lip NBR Oil Seal with Stainless Steel Spring — Stop Leaks on Rotating Shafts

A weeping gearbox, a leaking wheel hub, or a dripping pump shaft is more than a nuisance — it leads to contaminated lubricant, accelerated bearing wear, and costly downtime. Whether you are a professional mechanic, a farm equipment technician, or a hands-on DIYer rebuilding a differential or hydraulic pump, finding the exact replacement TC oil seal in the right metric size is often the hardest part of the job.

Each seal in this listing is a TC-type double lip rotary shaft oil seal made from NBR (nitrile rubber) with a stainless steel garter spring and a steel outer case. Available in inner diameters (ID) from 32mm (≈1.26") to 40mm (≈1.57"), outer diameters (OD) from 42mm (≈1.65") to 85mm (≈3.35"), and heights of 5mm, 7mm, 8mm, 10mm, or 12mm. Order as a single piece or save with a 10-piece pack.

These TC double lip NBR oil seals are widely used in automotive gearbox and differential rebuilds, agricultural and construction equipment shaft sealing, and industrial pump and motor shaft applications where a reliable metric rotary shaft seal is needed to retain oil and exclude contaminants simultaneously.

🔵 Compatibility Note: These are metric TC oil seals. Match the seal's ID to your shaft diameter, OD to your bore diameter, and height to your housing depth before ordering. Dimensions are listed as ID × OD in the variant selector. If you are unsure of your measurements, contact us to confirm.

⚠️ Tip: Always measure your existing seal or housing with calipers — do not rely solely on part numbers from other brands, as cross-references can vary by manufacturer.

✅ Key Features of These TC Double Lip NBR Oil Seals

🔒Double Lip Sealing Design — The primary lip retains oil and lubricant while the secondary dust lip blocks dirt, water, and debris from reaching the sealing surface, extending service life in contaminated environments.
🌀Stainless Steel Garter Spring — The corrosion-resistant stainless steel spring maintains consistent radial lip pressure against the shaft throughout the seal's service life, even as the lip material wears slightly over time.
🧪NBR Nitrile Rubber Lip — NBR compound resists petroleum-based oils, greases, hydraulic fluids, and water, making these metric rotary shaft seals suitable for gearboxes, differentials, pumps, and wheel hubs.
📐Wide Metric Size Range — With ID options from 32mm to 40mm and OD from 42mm to 85mm, this listing covers dozens of common shaft seal sizes used in automotive, agricultural, and industrial equipment.
🏗️Steel Outer Case for Secure Press Fit — The rigid steel outer shell ensures the seal presses squarely into the bore and stays in place under vibration and thermal cycling, preventing the spinning or walking common with all-rubber seals.
📦Single or 10-Piece Pack Options — Buy one seal for a single repair or order a 10-piece pack for fleet maintenance, workshop stock, or production line use — both options ship from our US warehouse.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

Measure the shaft diameter (this is your ID), the bore diameter (this is your OD), and the housing depth (this is the height). Match all three to the variant you select. For example, a 32mm shaft in a 52mm bore with a 7mm housing depth needs a 32mm × 52mm, 7mm seal. When in doubt, measure twice — a seal that is even 1mm off will not seat correctly.

What load or pressure can these TC oil seals handle?

TC-type double lip oil seals are generally designed for low-to-medium pressure dynamic applications. They are typically rated for shaft speeds up to approximately 4–8 m/s and pressures up to around 0.05 MPa (0.5 bar) under normal operating conditions. For high-pressure hydraulic circuits, a dedicated hydraulic seal is recommended.

Are these oil seals suitable for outdoor or wet environments?

Yes. The NBR lip material generally resists water, common oils, and greases well. The stainless steel spring resists corrosion better than carbon steel springs. However, NBR is not recommended for prolonged exposure to ozone, strong acids, or ketone-based fluids. For highly corrosive outdoor environments, consider a FKM (Viton) seal instead.

What shaft standards are these seals compatible with?

These are metric TC oil seals compatible with metric shafts and bores. The ID dimension corresponds directly to the shaft diameter. They are generally interchangeable with seals meeting ISO 6194-1 and DIN 3760 standards. Always verify the ID, OD, and height match your housing before installation.

What temperature range can NBR oil seals withstand?

NBR (nitrile rubber) oil seals typically operate reliably in a temperature range of approximately −40°F to +250°F (−40°C to +120°C). Short-term peaks up to +275°F (+135°C) are generally tolerable. For continuous high-temperature applications above 250°F, a silicone or FKM seal is typically recommended.

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

A TC double lip seal adds a secondary dust-exclusion lip behind the primary oil-retention lip. This secondary lip keeps contaminants — dirt, water, and debris — from reaching the primary sealing surface, extending seal life in dirty or wet operating environments such as agricultural equipment, gearboxes, and wheel hubs.

How do I install a TC oil seal correctly?

Clean the bore and shaft thoroughly. Apply a thin film of the sealed fluid or clean grease to the seal lip before installation. Press the seal in squarely using a seal driver or a flat block — never hammer directly on the seal face. The seal should sit flush with or just below the bore face. Avoid nicking the lip on sharp shaft edges; use a chamfer or installation sleeve if needed.
