Metric TC Oil Shaft Seal — Reliable Dust & Grease Protection for Rotating Shafts

When a worn or undersized shaft seal lets grease escape or contaminants creep in, the damage to bearings and housings adds up fast. Whether you are a maintenance technician rebuilding agricultural equipment, a small-batch manufacturer assembling gearboxes, or a repair technician servicing industrial machinery, finding the exact metric bore size you need should not be a project in itself. These metric TC double-lip oil shaft seals are stocked across a wide dimensional range — inner bore from 200 mm (7.87 in) up to 520 mm (20.47 in) — so you can match the seal to the shaft rather than the other way around.

Each seal is constructed with a nitrile rubber (NBR) sealing body bonded to a carbon steel outer case. The TC double-lip design features a primary sealing lip that retains lubricant and a secondary dust lip that blocks particulate ingress, with a garter spring behind the primary lip maintaining consistent radial load against the shaft. Depth (width) options range from 10 mm (0.39 in) to 25 mm (0.98 in) depending on the selected size combination, allowing fitment into both shallow and standard-depth housings.

Typical applications include agricultural gearbox shaft sealing for tractor PTO and axle assemblies, industrial pump and motor shaft sealing where grease retention is critical, and heavy equipment wheel hub and differential rebuilds requiring metric TC seals. Long-tail use cases also include conveyor drive shaft maintenance, hydraulic cylinder rod sealing in metric machinery, and replacement sealing in metric-dimensioned European and Asian equipment.

⚙️ Compatibility: Fits standard metric shaft and housing bores. Verify Inner Ø (shaft diameter), Outer Ø (housing bore), and Depth before ordering. Suitable for NBR-compatible media including mineral oils, greases, and water-based fluids up to approximately 100 °C (212 °F) continuous.

✅ Key Features of These Metric TC Double-Lip Oil Shaft Seals

🔩

TC Double-Lip Design

Primary sealing lip retains lubricant; secondary dust lip blocks contaminants — two lines of defence in one seal.

🌀

Integrated Garter Spring

Maintains consistent radial contact pressure on the shaft throughout the seal's service life, compensating for minor shaft runout.

🛡️

NBR Rubber Body

Nitrile rubber compound resists mineral oils, greases, and mild chemicals; rated for continuous service up to approximately 100 °C (212 °F).

🔧

Carbon Steel Outer Case

Rigid metal shell ensures a secure interference fit in the housing bore and resists distortion during installation and operation.

📐

Wide Metric Size Range

Inner bore from 200 mm to 520 mm with multiple outer diameter and depth combinations — covering agricultural, industrial, and heavy-equipment applications.

📦

Single-Piece Packing

Each variant is sold individually, letting you order the exact quantity needed for your repair or production run without overstocking.

❓ Frequently Asked Questions

How do I choose the correct seal size?

Measure three dimensions on your existing seal or housing: the inner diameter (shaft OD), the outer diameter (housing bore ID), and the depth (axial width of the housing groove). Match all three to the variant listed as Inner Ø x Outer Ø x Depth. If your shaft is worn, measure the housing bore and depth first, then confirm the shaft diameter falls within the seal's designed interference range.

What does "TC" mean for an oil seal?

TC designates a double-lip seal with a garter spring. The first (primary) lip faces the oil or grease side and is held against the shaft by the spring. The second (dust) lip faces outward and prevents dirt, water, and debris from reaching the primary lip. This two-lip arrangement makes TC seals the standard choice for most rotating shaft applications.

Are these seals strong enough for heavy agricultural and industrial use?

Yes. The carbon steel outer case provides a firm interference fit in the housing, and the NBR lip compound is formulated to withstand the mineral oils and greases used in agricultural gearboxes, industrial pumps, and heavy equipment differentials. For applications involving synthetic esters or aggressive chemicals, verify NBR compatibility with your specific fluid before installation.

What is the temperature and fluid compatibility of these seals?

The NBR rubber body is rated for continuous service up to approximately 100 °C (212 °F) and intermittent peaks up to around 120 °C (248 °F). Compatible fluids include mineral oils, petroleum-based greases, and water-based lubricants. NBR is not recommended for use with phosphate-ester hydraulic fluids, ketones, or strong acids — use FKM (Viton) seals for those media.

How do I install a large-bore metric TC oil seal without damaging it?

Clean the housing bore and shaft thoroughly. Lightly lubricate the outer case OD with clean oil or grease to ease installation. Use a seal driver or a flat pressing plate that contacts only the outer case — never strike the rubber lip directly. Press the seal in squarely until the face is flush with or just below the housing surface. Protect the primary lip from sharp shaft edges by using a sleeve or chamfer during installation.

Can I use these seals to replace OEM seals on European or Asian metric machinery?

In most cases, yes. These seals follow standard metric TC dimensions used across European and Asian equipment manufacturers. As long as the Inner Ø, Outer Ø, and Depth match your OEM seal's stamped dimensions, the replacement should fit correctly. Always cross-reference the three dimensions rather than relying solely on a part number, as OEM numbering systems vary by brand.

What if my required size is not listed as a variant?

The listed variants cover the most common metric TC seal sizes in the 200–520 mm bore range. If your exact combination of Inner Ø, Outer Ø, and Depth is not shown, please use the Contact Us link to send your three dimensions — we can advise on the closest available size or source a custom option.

These o rings are a great for my ear tunnels

These o rings are a great for my ear tunnels, always loosing one here and there, I always have a new ones in the drawer. Being silicone, don't have any reactions compared to standard rubber ones I purchased at hardware stores, plus much less expensive. Purchased 16mm I'd to use on 19mm tunnels, and stay on great, might be able to get away with 17mm rings, but really happy with my choice.

Will never order from these folks again

I waited a long time and that’s all I received was the eyebolt with no threaded rod attached to it

Perfect they are really made well and I used them for my car

Perfect they are really made well and I used them for my car. The only thing I had a great for us. It took three weeks to get here. So shipping was slow.

did not include wing nuts
