Are these seals suitable for outdoor or wet environments?

FKM (Viton) rubber offers good resistance to moisture, mild chemicals, and temperature extremes (typically –20°C to +200°C / –4°F to +392°F), making these seals suitable for outdoor machinery and wet environments. However, prolonged submersion or exposure to aggressive solvents should be confirmed with us before ordering.

How do I convert millimeter sizes to inches?

Divide the mm value by 25.4. For example: 180mm ÷ 25.4 ≈ 7.09" | 190mm ≈ 7.48" | 200mm ≈ 7.87" | 220mm ≈ 8.66" | 15mm ≈ 0.59". Use these conversions when cross-referencing imperial part numbers.

TC Oil Seal ID 180–200mm — FKM Rubber Dual Lip Rotary Shaft Seal for Industrial & Agricultural Equipment

When a leaking shaft seal on a gearbox, pump, or heavy-duty axle brings your operation to a halt, finding the exact replacement fast is everything. These TC oil seals with ID 180–200mm are engineered for maintenance professionals, equipment rebuilders, and industrial DIYers who need a reliable rotary shaft seal that fits right the first time — without hunting through a distributor's back catalog.

Each seal is a TC skeleton type: a steel inner reinforcing ring (skeleton) bonded to FKM (Viton) rubber, with a dual-lip design — one primary sealing lip to retain lubricant and one secondary dust-exclusion lip to block contaminants. Available in 62 size combinations spanning ID 180mm (≈7.09") to 200mm (≈7.87"), OD 200mm (≈7.87") to 250mm (≈9.84"), and thickness 10mm (≈0.39") to 20mm (≈0.79"). Sold individually (1 PCS per order).

Typical applications include industrial gearbox shaft seals, centrifugal pump rotary seals, agricultural tractor axle seals, and heavy equipment drivetrain rebuilds — anywhere a large-bore FKM dual lip oil seal is required to handle heat, oil, and outdoor exposure.

ℹ️ Compatibility Note: These seals follow standard metric TC dimensions. Verify your equipment's ID × OD × Thickness (in mm) before ordering. Cross-reference with DIN 3760 / ISO 6194 Type TC where applicable.

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

🔩Steel Skeleton Reinforcement — The inner metal ring maintains dimensional stability under press-fit installation, preventing distortion in large-bore housings common in industrial gearbox shaft seal applications.
🛡️Dual Lip Design — The primary FKM lip retains lubricant while the secondary dust lip blocks dirt, water, and debris — critical for agricultural tractor axle seals and outdoor equipment exposed to contamination.
🌡️FKM (Viton) Rubber Construction — Resists petroleum oils, synthetic lubricants, and temperatures typically from –20°C to +200°C (–4°F to +392°F), outperforming standard NBR seals in high-heat drivetrain environments.
📐62 Metric Size Combinations — ID 180–200mm × OD 200–250mm × Thickness 10–20mm covers a wide range of large-bore rotary shaft seal replacements without special ordering.
⚙️Spring-Loaded Sealing Lip — A garter spring maintains consistent radial lip pressure against the shaft surface, compensating for minor shaft runout and extending service life in centrifugal pump rotary seal applications.
🚚Ships from US Warehouse — Stocked domestically for fast delivery, so your equipment rebuild or emergency repair isn't waiting weeks for an overseas shipment.

⚠️ Before You Order: Always measure your shaft ID, housing bore OD, and housing depth (thickness) directly. Do not rely solely on part numbers from other brands — metric TC seal dimensions can vary slightly between manufacturers.

❓ Frequently Asked Questions

How do I choose the right size TC oil seal?

Measure three dimensions on your equipment: (1) the shaft's outer diameter — this is the seal's ID; (2) the housing bore's inner diameter — this is the seal's OD; (3) the housing depth — this is the seal's Thickness. All three must match. For example, a 190*220*15mm seal fits a 190mm (≈7.48") shaft inside a 220mm (≈8.66") bore with a 15mm (≈0.59") deep housing. When in doubt, measure twice and consult your equipment's service manual.

How do I convert these millimeter sizes to inches?

Divide the mm value by 25.4. Quick reference for this product range:

180mm ÷ 25.4 ≈ 7.09"
185mm ÷ 25.4 ≈ 7.28"
190mm ÷ 25.4 ≈ 7.48"
195mm ÷ 25.4 ≈ 7.68"
200mm ÷ 25.4 ≈ 7.87"
220mm ÷ 25.4 ≈ 8.66" | 230mm ≈ 9.06" | 240mm ≈ 9.45" | 250mm ≈ 9.84"
15mm ≈ 0.59" | 18mm ≈ 0.71" | 20mm ≈ 0.79"

Use these when cross-referencing imperial part numbers from OEM manuals.

What pressure and load can these seals handle?

TC-type skeleton oil seals are generally designed for low-to-medium pressure applications — typically up to 0.05 MPa (≈7 psi) of static pressure. They are not intended for high-pressure hydraulic circuits. For dynamic shaft applications, the garter spring maintains consistent lip contact under normal radial loads. Contact us to confirm suitability for your specific pressure conditions.

Are these FKM seals suitable for outdoor or wet environments?

Yes. FKM (Viton) rubber offers good resistance to moisture, mild chemicals, UV exposure, and temperature extremes — typically –20°C to +200°C (–4°F to +392°F). This makes these seals well-suited for outdoor agricultural machinery, construction equipment, and marine-adjacent applications. Prolonged submersion or exposure to aggressive solvents (ketones, esters) should be confirmed with us before ordering.

What shaft surface speed is compatible with these TC oil seals?

In this large-bore size range (ID 180–200mm), TC skeleton seals are generally compatible with shaft surface speeds up to approximately 4–8 m/s, depending on lubrication conditions, shaft surface finish (Ra ≤ 0.8 µm recommended), and operating temperature. Higher speeds may require a PTFE-lip or labyrinth seal variant. Contact us to confirm for your application.

What is the difference between a TC seal and a SC or VC seal?

TC seal: Metal skeleton + dual lip (primary sealing lip + secondary dust exclusion lip). Most common for general industrial rotary shaft applications.
SC seal: Metal skeleton + single lip only — no dust exclusion lip.
VC seal: All-rubber, no metal skeleton — used where press-fit rigidity is less critical.
TC is the standard choice when you need both oil retention and contamination exclusion, which is why it's the go-to for gearbox and pump rebuilds.

Can I use these seals in gearboxes, pumps, and agricultural equipment?

Yes. TC-type FKM oil seals in the 180–200mm ID range are commonly used in industrial gearboxes, centrifugal pumps, agricultural tractor axles (tractors, combines, harvesters), and heavy equipment drivetrains. Always verify the exact ID × OD × Thickness against your equipment's service manual before installation to ensure a proper press fit.
