FKM TC Oil Seal — Reliable Rotary Shaft Sealing for 50–60mm ID Applications

When a worn or incorrect oil seal lets grease escape or lets dirt in, the damage to bearings and shafts can be costly. Mechanics, equipment technicians, and serious DIYers working on gearboxes, axles, pumps, and industrial machinery need a FKM TC oil seal that holds up under heat, pressure, and contamination — not one that cracks or leaks after a few months.

Each seal in this listing is a TC double-lip rotary shaft oil seal made from FKM (Viton) elastomer with a carbon steel outer case and a garter spring that maintains consistent lip contact. Inner diameters (ID) range from 50mm (≈1.97") to 60mm (≈2.36"), outer diameters (OD) from 62mm (≈2.44") to 120mm (≈4.72"), and thicknesses from 5mm (≈0.20") to 13mm (≈0.51"). Over 150 size combinations are available — select your exact ID × OD × Thickness from the variant dropdown.

These seals are commonly used in automotive differential and transmission rebuilds, agricultural equipment driveshafts, hydraulic pump shafts, electric motor end caps, and industrial gearbox overhauls where a reliable rotary shaft grease seal with double-lip protection is required.

🔵 Compatibility Note: These are metric TC-type oil seals. Verify your shaft ID, housing bore OD, and housing depth (thickness) before ordering. Size format: ID × OD × Thickness (mm). Not interchangeable with inch-standard seals without measurement confirmation.

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

  • 🌡️FKM (Viton) Elastomer — Withstands continuous temperatures typically up to 200°C (392°F), outperforming standard NBR seals in high-heat engine and industrial environments.
  • 🔒TC Double-Lip Design — Primary sealing lip retains oil and grease; secondary dust lip blocks dirt, debris, and moisture ingress for extended bearing and shaft life.
  • 🌀Garter Spring Loaded — Internal coil spring maintains consistent radial lip pressure against the shaft, compensating for minor wear and ensuring a reliable seal over time.
  • 🏗️Carbon Steel Outer Case — Rigid metal shell provides a secure press-fit into the housing bore, resisting blowout under pressure and preventing seal rotation.
  • 📐150+ Metric Size Variants — ID range 50–60mm, OD range 62–120mm, thickness 5–13mm. Covers a wide range of gearbox oil seal, axle seal, and pump shaft seal replacement needs.
  • 🧪Broad Chemical Resistance — FKM compound is generally compatible with petroleum oils, synthetic lubricants, hydraulic fluids, and fuels — suitable for demanding rotary shaft grease seal applications.

⚠️ Sizing Tip: If you are unsure of your seal dimensions, measure the shaft diameter (ID), the bore hole diameter (OD), and the housing depth (thickness) with a caliper before selecting a variant. Contact us to confirm if your size is not listed.

❓ Frequently Asked Questions

How do I choose the right oil seal size?

Measure the shaft diameter (ID), the bore diameter (OD), and the housing depth (thickness) with calipers. Match all three dimensions to the variant listed as ID*OD*Thick. For example, 60*80*10mm means 60mm inner diameter, 80mm outer diameter, and 10mm thick (≈0.39"). When in doubt, go by the shaft and bore measurements first — thickness is generally the most forgiving dimension.

What is the difference between TC and SC oil seals?

TC seals have two sealing lips — a primary lip that contacts the shaft and a secondary dust lip — making them generally more effective at keeping contaminants out. SC seals have a single lip. For most rotary shaft applications involving grease, oil, or dust exposure, TC is the recommended choice.

What temperature range can FKM oil seals handle?

FKM (Viton) seals typically withstand continuous operating temperatures from approximately -20°C to +200°C (-4°F to +392°F). This makes them suitable for high-heat environments such as engine bays, industrial machinery, and hydraulic systems where standard NBR seals may degrade or harden prematurely.

Are these oil seals suitable for outdoor or wet environments?

Yes. FKM material is generally resistant to water, weathering, ozone, and many chemicals. The double-lip TC design adds an extra barrier against moisture and dirt ingress, making these seals a solid choice for outdoor equipment, agricultural machinery, and marine-adjacent applications.

What shaft speed can these seals handle?

Rotary shaft oil seals of this type are typically rated for shaft surface speeds up to approximately 4–8 m/s depending on the specific size, lubrication, and installation conditions. For higher-speed applications, ensure the shaft surface finish is smooth (typically Ra 0.2–0.8 µm) and the seal lip is lubricated at installation.

What fluids are these FKM seals compatible with?

FKM seals are generally compatible with petroleum-based oils, synthetic oils, hydraulic fluids, fuels, and many aggressive chemicals. They are not typically recommended for use with ketones, certain esters, or hot steam. Always verify compatibility with your specific fluid before installation.

How do I install a TC oil seal correctly?

Clean the housing bore and shaft. Lightly lubricate the seal lip and shaft with the fluid being sealed. Press the seal squarely into the bore using a seal driver or a flat plate — never hammer directly on the seal face. Ensure the seal sits flush or slightly below the housing face. Avoid nicking the lip during installation, as even minor damage can cause immediate leakage.
