TC Oil Seal 46–48mm ID — Stop Leaks on Rotary Shafts with the Right Dual Lip Seal

When a worn or incorrectly sized shaft seal lets oil seep past a gearbox, differential, or pump housing, the mess is only the beginning — contamination, bearing failure, and costly downtime follow. Mechanics, equipment owners, and DIY rebuilders working on metric-shaft machinery need a seal that fits precisely and holds up under real operating conditions.

Each seal in this listing is a TC-type skeleton oil seal with a 46mm, 47mm, or 48mm inner diameter (ID). The outer diameter (OD) and thickness vary by variant — sizes range from 46×56×6mm up to 48×100×12mm, covering a wide spread of bore housings. All seals are made from NBR 70 (nitrile rubber, 70 Shore A) with a carbon-steel skeleton insert and a dual-lip design: a primary oil-retention lip with a garter spring, plus a secondary dust-exclusion lip. Available individually (1 PCS) or in a 5-pack for workshop stock.

These TC dual lip seals are commonly used in automotive gearbox and differential rebuilds, agricultural tractor PTO and axle shafts, and industrial pump and motor shaft sealing — anywhere a metric rotary shaft seal with an ID in the 46–48mm range is needed.

ℹ️ Compatibility Note: These are metric TC-type seals conforming generally to DIN 3760 / ISO 6194. Select your variant by matching all three dimensions — ID × OD × Thickness — to your application. If you are unsure of your housing bore diameter, contact us to confirm before ordering.

✅ Key Features of These TC Dual Lip Rotary Shaft Oil Seals

🔩Dual-Lip TC Design — The primary garter-spring-loaded lip retains oil while the secondary lip blocks dust and moisture ingress, making these seals well-suited for dirty or wet environments like wheel hubs and agricultural axles.
🧱Carbon-Steel Skeleton Insert — The rigid metal case maintains dimensional stability during press-fit installation into the bore housing, reducing the risk of distortion that can cause early seal failure.
🌡️NBR 70 Compound — Nitrile rubber at 70 Shore A hardness provides reliable resistance to petroleum-based oils, grease, and water across a typical operating range of -40°F to +212°F (-40°C to +100°C).
📐Wide Size Selection — With IDs of 46mm, 47mm, and 48mm and ODs from 56mm to 100mm, this listing covers a broad range of metric rotary shaft seal applications without needing to source from multiple suppliers.
📦Single or 5-Pack Quantity Options — Order one seal for a single repair or choose the 5-pack for workshop inventory, fleet maintenance programs, or applications where periodic seal replacement is part of a scheduled service interval.
🚚Ships from US Warehouse — Stocked domestically for faster delivery to US addresses, avoiding the extended lead times common with direct overseas sourcing for metric oil seal replacements.

⚠️ Before You Order: Always verify all three dimensions (ID × OD × Thickness) against your original seal or housing drawing. A seal that is even 1–2mm off in OD will not seat correctly and may leak immediately.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

Measure the shaft diameter (ID), the bore diameter (OD), and the housing depth (thickness) with calipers. For example, a 48×65×10mm seal has a 48mm (≈1.89") inner diameter, 65mm (≈2.56") outer diameter, and 10mm (≈0.39") thickness. Match all three dimensions exactly to your application. When in doubt, measure the old seal rather than relying on a parts catalog number alone.

What load or pressure can these TC oil seals handle?

TC skeleton oil seals are generally rated for low-to-medium pressure applications. They are typically designed for shaft speeds up to around 4–8 m/s and static pressures up to approximately 0.05 MPa. For high-pressure hydraulic circuits, a different seal type is recommended. Contact us if you need to confirm suitability for a specific application.

Are these seals suitable for outdoor or wet environments?

Yes. NBR (nitrile rubber) offers good resistance to water, oil, and mild chemicals, making these seals suitable for outdoor and wet environments. However, NBR is not recommended for prolonged exposure to ozone, strong acids, or ketones. For extreme outdoor UV exposure, consider FKM (Viton) alternatives.

What shaft standards are compatible with these seals?

These are metric TC-type radial shaft seals conforming generally to DIN 3760 / ISO 6194 standards. They fit metric shafts with IDs of 46mm, 47mm, or 48mm. Confirm the bore housing diameter matches the OD listed in the variant you select. They are not designed for inch-standard shafts without verifying the exact dimensions match.

How do I know if I need a single-lip or dual-lip seal?

A dual-lip TC seal (like these) provides an extra dust-exclusion lip in addition to the primary oil-retention lip. This is generally preferred in environments with dirt, dust, or moisture ingress — such as agricultural equipment, wheel hubs, and gearboxes. Single-lip seals are typically used in cleaner, controlled environments where contamination ingress is not a concern.

What is the difference between buying 1 PCS and 5 PCS?

Both options ship the identical seal. The 5 PCS pack offers a lower per-unit cost and is ideal for fleet maintenance, workshop stock, or applications where you anticipate future replacements. The 1 PCS option is best for a single repair or fitment test before committing to a larger quantity.

What temperature range can NBR 70 seals withstand?

NBR 70 (70 Shore A hardness nitrile rubber) typically performs reliably in a temperature range of approximately -40°F to +212°F (-40°C to +100°C). Short-term peaks up to around +250°F (+120°C) are generally tolerable, but continuous high-heat applications may require FKM (Viton) seals instead.
