How do I choose the right oil seal size?

Measure your shaft's outer diameter (this becomes the seal's ID), then measure the bore housing diameter (this becomes the OD). Thickness should match the housing groove depth. For example, a 60mm shaft in an 80mm bore with a 10mm groove takes a 60 x 80 x 10mm seal. When in doubt, consult your equipment's service manual.

What does FKM mean and why does it matter?

FKM (Fluoroelastomer, also known as Viton®) is a synthetic rubber that generally withstands temperatures from approximately -20°C to +200°C (-4°F to +392°F) and resists petroleum oils, hydraulic fluids, and many chemicals. It typically outperforms standard NBR seals in high-temperature or chemically aggressive environments.

Can these oil seals be used outdoors or in wet environments?

FKM double lip seals are generally suitable for outdoor and wet conditions. The outer secondary lip acts as a dust and moisture excluder, while the inner lip retains lubricant. For fully submerged or high-pressure washdown applications, confirm the specific pressure rating with us before ordering.

What equipment are TC oil seals commonly used in?

TC skeleton oil seals are widely used in automotive gearboxes, differentials, engine crankshafts, agricultural machinery, industrial pumps, electric motors, and hydraulic cylinders — anywhere a rotating shaft exits a lubricated housing.

How do I install a TC oil seal without damaging it?

Use a seal driver or a flat press plate to push the seal in squarely — never hammer directly on the seal face. Lightly lubricate the seal lip with clean grease or the fluid being sealed before installation. Ensure the shaft has no sharp edges or burrs that could cut the lip.

TC FKM Double Lip Oil Seal — Stop Leaks on Rotating Shafts, ID 52–70mm

If you've dealt with grease weeping past a shaft seal, contaminated gearbox oil, or a pump that keeps losing lubricant, you know how quickly a failed rotary shaft seal turns into a bigger repair. Mechanics, equipment technicians, and serious DIYers working on gearboxes, differentials, motors, and hydraulic systems need a seal that holds up — not one that hardens, cracks, or lets contaminants in after a few months of service.

Each listing is for 1 piece of a TC-type skeleton oil seal made with an FKM (fluoroelastomer) sealing lip and a steel-reinforced skeleton body. Available in a wide range of sizes with an inner diameter (ID) from 52mm (≈2.05") to 70mm (≈2.76"), outer diameter (OD) from 62mm (≈2.44") to 140mm (≈5.51"), and thickness from 5mm (≈0.20") to 13mm (≈0.51"). Select your exact ID × OD × Thickness from the variant dropdown above.

These TC double lip oil seals are suited for automotive gearbox and differential shaft sealing, industrial pump and motor shaft applications, and agricultural equipment rotary shaft seals where resistance to petroleum oils, hydraulic fluids, and moderate heat is required.

ℹ️ Compatibility: Fits metric shafts and housings following ISO 6194-1 / DIN 3760 standards. Always verify your shaft OD (= seal ID), housing bore (= seal OD), and groove depth (= seal thickness) before ordering.

✅ Key Features of These TC FKM Double Lip Oil Seals

🔵 FKM Fluoroelastomer Lip — Resists petroleum oils, hydraulic fluids, and temperatures typically up to +200°C (+392°F), outperforming standard NBR seals in demanding environments.
🛡️ TC Double Lip Design — The inner lip retains lubricant while the outer dust lip excludes dirt, water, and debris — a critical advantage for gearbox shaft sealing in dirty or wet conditions.
🔩 Steel-Reinforced Skeleton Body — The rigid metal insert maintains the seal's round shape during press-fit installation and prevents distortion under housing clamping forces.
📐 Wide Size Range in One Listing — ID 52–70mm with OD up to 140mm and thickness 5–13mm covers a broad range of rotary shaft seal replacements without hunting across multiple SKUs.
⚙️ Metric Dimensions, ISO-Compatible — All sizes follow metric standards compatible with ISO 6194-1 and DIN 3760 housings, making cross-referencing to OEM specs straightforward.
🔄 Suitable for Moderate-Speed Rotating Shafts — Designed for typical shaft surface speeds found in automotive differentials, industrial pumps, and agricultural equipment drive shafts.

❓ Frequently Asked Questions

How do I measure and choose the correct oil seal size?

Three measurements determine your seal: ID = your shaft's outer diameter, OD = your housing bore diameter, Thickness = your housing groove depth. For example, a 60mm shaft in an 80mm bore with a 10mm groove needs a 60 × 80 × 10mm seal. In inches: 60mm ≈ 2.36", 80mm ≈ 3.15", 10mm ≈ 0.39". Always measure with calipers rather than relying on worn seal markings.

What is FKM and how does it compare to standard rubber seals?

FKM (Fluoroelastomer, commercially known as Viton®) generally withstands temperatures from approximately -20°C to +200°C and resists petroleum oils, gear oils, hydraulic fluids, and many chemicals. Standard NBR (nitrile) seals typically max out around +120°C and can degrade faster in high-temperature or chemically aggressive environments. FKM is the preferred choice for gearboxes, differentials, and industrial equipment running hot or with synthetic fluids.

Can I use these seals outdoors or in wet, muddy conditions?

Yes, in most cases. The TC double lip design includes an outer dust/dirt exclusion lip specifically to keep contaminants out — making it well-suited for agricultural equipment, outdoor power tools, and machinery exposed to water and debris. For fully submerged applications or high-pressure washdown environments, contact us to confirm suitability before ordering.

What shaft speed and pressure can these seals handle?

TC-type rotary shaft seals are typically rated for shaft surface speeds up to approximately 4–8 m/s, which covers most automotive, agricultural, and general industrial applications. They are generally designed for low differential pressure (typically under 0.05 MPa / ~7 psi). For high-speed spindles, pressurized housings, or unusual operating conditions, contact us with your application details.

Are these seals compatible with my metric housing and ISO standards?

All dimensions are metric and generally compatible with ISO 6194-1 and DIN 3760 housing tolerances — the most common standards for rotary shaft seals in automotive and industrial equipment worldwide. Always verify your housing bore and shaft diameter with calipers before ordering to ensure an exact fit.

What equipment are TC skeleton oil seals typically used in?

TC oil seals are widely used in: automotive gearboxes, differentials, and crankshafts; agricultural tractor and implement drive shafts; industrial electric motors and pumps; hydraulic cylinders; and general machinery wherever a rotating shaft exits a lubricated housing. If your application involves a spinning shaft and a sealed lubricant cavity, a TC seal is generally the right type.

How do I install a TC oil seal correctly without damaging it?

Use a seal driver or flat press plate sized to the OD to press the seal in squarely — never strike the seal face directly with a hammer. Lightly coat the seal lip with clean grease or the fluid being sealed before installation. Inspect the shaft for burrs, nicks, or sharp edges and smooth them before fitting the seal. Press until the seal face is flush with or just below the housing face.
