TC FKM Oil Seal for 45–48mm Shafts — Stop Leaks at the Source

A weeping gearbox seal or a leaking pump shaft is more than a nuisance — it contaminates surrounding components, creates slip hazards, and signals accelerating wear. Mechanics, equipment operators, and serious DIYers who need a reliable replacement rotary shaft seal for 45mm to 48mm shafts will find the right fit here. These TC-type FKM oil seals are engineered for demanding rotating shaft applications where standard rubber seals fall short.

Each seal is a single-piece TC (double-lip) design with an FKM (Viton) sealing lip and a carbon steel outer case. Sizes are expressed as ID × OD × Width in millimeters — for example, 45 × 62 × 8 means a 45mm shaft bore, 62mm housing bore, and 8mm seal width (≈ 1.77" × 2.44" × 0.31"). Available in a wide range of ID × OD × thickness combinations spanning 45mm–48mm inner diameters and outer diameters from 52mm up to 100mm, with widths of 7mm, 8mm, 10mm, or 12mm depending on the variant.

These FKM rotary shaft seals are well suited for gearbox output shaft sealing, differential pinion seal replacement, hydraulic pump shaft seals, and electric motor bearing housing seals — anywhere a metric TC oil seal for a 45–48mm shaft is required.

🔵 Compatibility Note: Verify all three dimensions — Inner Diameter (ID), Outer Diameter (OD), and Width — against your housing before ordering. Variant format: ID × OD × Width (mm). Example: 45 × 62 × 8 = 45mm shaft / 62mm bore / 8mm wide.

⚠️ Tip: If you are unsure of your seal dimensions, measure with calipers before selecting a variant. Shaft diameter = ID; housing bore = OD; groove depth = Width.

✅ Key Features of These TC FKM Rotary Shaft Oil Seals

🛡️FKM (Viton) Lip Material — Resists petroleum oils, gear oils, hydraulic fluids, and fuels across a wide temperature range, making these seals a reliable choice for high-heat gearbox shaft sealing applications.
🔄TC Double-Lip Design — The primary lip retains lubricant while the secondary dust lip excludes dirt, water, and contaminants — critical for outdoor equipment and agricultural machinery shaft seals.
⚙️Carbon Steel Outer Case — Provides a firm press-fit into the housing bore, maintaining concentricity and preventing the seal from spinning or walking out under vibration.
📐Wide Size Selection — Covers 45mm, 46mm, 47mm, and 48mm shaft diameters with multiple OD and width combinations, reducing the need to source non-standard metric TC oil seal sizes from specialty suppliers.
🌡️Broad Temperature Tolerance — FKM compound generally performs from approximately -20°C to +200°C (-4°F to +392°F), suitable for both cold-start conditions and sustained high-temperature operation in pumps and motors.
🔧Standard Metric Dimensions — Dimensioned to DIN 3760 / ISO 6194 conventions, ensuring straightforward cross-referencing against OEM part numbers and compatibility with standard metric shaft and housing tolerances.

❓ Frequently Asked Questions

How do I choose the right oil seal size?

Measure your shaft diameter (ID), housing bore (OD), and groove depth (width) with calipers. The variant format is ID × OD × Width in mm. For example, a 45 × 62 × 8 seal fits a 45mm shaft (≈ 1.77") in a 62mm bore (≈ 2.44") with an 8mm groove (≈ 0.31"). Always verify all three dimensions before ordering — a seal that is even 1mm off in OD will not press-fit correctly.

What load or pressure can these oil seals handle?

TC-type rotary shaft seals are generally designed for low-to-medium pressure applications. They typically handle lip contact pressures up to around 0.3 bar (≈ 4.4 psi) in dynamic sealing. For high-pressure hydraulic circuits, a different seal type is recommended. Contact us to confirm suitability for your specific application.

Are these seals suitable for outdoor or wet environments?

Yes. The FKM lip material offers good resistance to moisture, weathering, and many chemicals. The dual-lip TC design includes a secondary dust lip that helps exclude water and contaminants, making it suitable for outdoor machinery, agricultural equipment, and applications exposed to the elements.

What shaft and housing standards are these compatible with?

These are metric-dimensioned TC oil seals generally conforming to DIN 3760 / ISO 6194 dimensional standards. They are compatible with standard metric shafts and housings. Always verify the ID, OD, and width match your housing specifications. They are not designed for inch-dimensioned (imperial) housings without confirming the dimensions match.

What fluids and temperatures can FKM oil seals resist?

FKM (Viton) seals typically resist petroleum-based oils, gear oils, hydraulic fluids, fuels, and many synthetic lubricants. They generally perform in temperatures ranging from approximately -20°C to +200°C (-4°F to +392°F), making them suitable for high-heat gearboxes, engine applications, and industrial pump shaft sealing where standard NBR seals degrade prematurely.

How do I install a TC oil seal correctly?

Clean the housing bore and shaft. Lightly lubricate the seal lip 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. Protect the lip from keyways or splines during installation using a thin sleeve or tape.

Can I use these seals in gearboxes and differentials?

Yes. TC FKM oil seals are commonly used in gearboxes, differentials, axles, pumps, and electric motors where a rotating shaft exits a housing. They are a frequent choice for gearbox output shaft seal replacement and differential pinion seal applications. Verify shaft speed and fluid compatibility for your specific unit before installation.
