FKM TC Oil Seals — Double Lip Rotary Shaft Seals for Reliable Dust & Grease Exclusion

When a worn or incorrectly sized shaft seal lets grease escape or contaminants enter, the damage to bearings and gearboxes adds up fast. Mechanics, equipment rebuilders, and serious DIYers who work on agricultural machinery, industrial gearboxes, pumps, and automotive drivetrains need a seal they can spec with confidence — one that holds up to heat, chemical exposure, and continuous rotation without weeping.

These FKM TC double lip rotary shaft oil seals are constructed from fluoroelastomer (FKM/FPM) rubber bonded to a carbon steel case, with a garter spring that maintains consistent radial lip pressure throughout the service life. Available in inner diameters from 52 mm to 60 mm (approximately 2.05 in to 2.36 in), outer diameters from 62 mm to 120 mm (approximately 2.44 in to 4.72 in), and thicknesses from 5 mm to 13 mm (approximately 0.20 in to 0.51 in). The TC profile features a primary sealing lip with spring and a secondary dust-exclusion lip — both moulded from FKM for broad chemical resistance.

Typical applications include agricultural PTO shaft seals, industrial pump and gearbox rebuilds, hydraulic cylinder rod seals, and automotive rear axle or differential shaft seals where standard NBR seals fail prematurely due to elevated temperatures or aggressive lubricants. Sold individually (1 pcs) or in packs of 5 for workshop stock.

⚙️ Compatibility: Verify shaft diameter, housing bore, and seal width against your equipment service manual before ordering. Size format is ID × OD × Thickness (mm). Select your exact size from the variant options above.

✅ Key Features of These FKM TC Oil Seals

🔬 FKM Fluoroelastomer Lip Material — Resists petroleum oils, synthetic lubricants, and temperatures typically ranging from −20 °C to +200 °C (−4 °F to +392 °F), outperforming standard NBR seals in high-heat or chemically aggressive environments.
🌀 Garter Spring-Loaded Primary Lip — The integrated garter spring maintains consistent radial contact force on the shaft as the lip wears, extending effective sealing life and reducing the risk of early leakage.
🛡️ TC Double Lip Design — The secondary dust-exclusion lip blocks abrasive particles, moisture, and contaminants from reaching the primary sealing lip, making these seals suitable for outdoor and dirty-environment applications.
🔩 Carbon Steel Outer Case — The rigid metal shell provides a secure press-fit into the housing bore, resisting rotation and maintaining concentricity under dynamic shaft loads.
📐 Wide Metric Size Range — Inner diameters from 52 mm to 60 mm with multiple OD and thickness combinations allow precise matching to metric shafts across agricultural, industrial, and automotive equipment.
📦 Flexible Pack Quantities — Available as a single piece (1 pcs) for one-off repairs or in a 5-piece pack for workshop stock, with per-unit savings on the larger quantity.

❓ Frequently Asked Questions

How do I identify the correct seal size for my application?

Measure the shaft diameter (ID), the housing bore diameter (OD), and the depth of the seal recess (Thickness) using calipers. Cross-reference these three dimensions with the size listed in your equipment's service manual. The size format used here is ID × OD × Thickness in millimetres. If the housing is worn, measure the bore carefully — an oversized bore may require a sleeve or a different OD.

Why choose FKM over NBR for a rotary shaft seal?

NBR (nitrile) seals are suitable for standard mineral oils at moderate temperatures. FKM (fluoroelastomer) seals are the correct choice when operating temperatures exceed approximately 120 °C, when synthetic lubricants such as PAO or ester-based oils are used, or when the seal is exposed to fuels, hydraulic fluids, or aggressive chemicals. FKM also offers better ozone and UV resistance for outdoor equipment.

What does the TC designation mean on an oil seal?

TC is a standard seal profile designation indicating a double-lip seal with a metal case and a garter spring on the primary lip. The first lip (with spring) provides the primary fluid seal; the second lip acts as a dust and contamination excluder. This is the most common profile for rotating shaft applications in gearboxes, pumps, and axles.

Can these seals be used in agricultural or outdoor equipment?

Yes. The TC double lip design is specifically suited to outdoor and agricultural environments where dust, soil, water, and debris are present. The secondary lip blocks contaminants from reaching the primary sealing surface. FKM's resistance to ozone and UV degradation also makes it more durable than NBR in exposed outdoor conditions.

How do I install a TC oil seal without damaging the lip?

Clean the housing bore and shaft thoroughly. Apply a thin film of the lubricant being sealed to the seal lip before installation. Use a seal driver or a flat press plate to press the seal squarely into the bore — never hammer directly on the seal face. Ensure the seal is flush with or slightly below the housing face as specified by the equipment manufacturer. Protect the lip from sharp shaft edges or keyways during installation using a sleeve or tape.

Is the 1 pcs or 5 pcs pack better value?

The 5-piece pack offers a lower per-unit cost compared to buying five individual seals separately, making it the practical choice for workshop stock, fleet maintenance, or when the same seal size is used across multiple machines. The 1-piece option is ideal for a single repair where only one seal is needed.

What shaft surface finish is recommended for these seals?

For optimal sealing life, the shaft surface in the contact zone should have a finish of approximately Ra 0.2–0.8 µm (8–32 µin) with a lead-free ground or polished finish. Rough, scored, or corroded shaft surfaces will cause accelerated lip wear and early leakage. If the shaft is worn or grooved, a repair sleeve (speedi-sleeve) should be fitted before installing the new seal.
