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.
| Seal Type | TC (Skeleton, Spring-Loaded, Dual Lip) |
|---|---|
| Inner Diameter (ID) Range | 180mm (≈7.09") — 200mm (≈7.87") |
| Outer Diameter (OD) Range | 200mm (≈7.87") — 250mm (≈9.84") |
| Thickness Range | 10mm (≈0.39") — 20mm (≈0.79") |
| Lip Material | FKM (Fluoroelastomer / Viton) |
| Inner Reinforcement | Steel Skeleton Ring |
| Number of Lips | 2 (Primary sealing lip + secondary dust exclusion lip) |
| Spring Type | Garter spring (lip-loaded) |
| Operating Temperature | Typically –20°C to +200°C (–4°F to +392°F) |
| Pressure Rating | Typically up to 0.05 MPa (≈7 psi) static; contact us to confirm |
| Shaft Surface Speed | Generally up to 4–8 m/s; see variant options |
| Standard Reference | DIN 3760 / ISO 6194 Type TC (metric) |
| Quantity per Order | 1 PCS |
| Finish / Color | Black rubber with bare metal skeleton |
| Compatible Lubricants | Petroleum oils, synthetic gear oils, greases (verify for specialty fluids) |
| Exact Size | See variant options |
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.
Divide the mm value by 25.4. Quick reference for this product range:
Use these when cross-referencing imperial part numbers from OEM manuals.
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.
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.
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.
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.
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.
