FKM TC Oil Seals Metric Size — Stop Leaks and Protect Bearings on Large Industrial Shafts

When a rotary shaft seal fails on a gearbox, hydraulic pump, or industrial motor, the result is more than an oil puddle — it means contaminated bearings, unplanned downtime, and costly repairs. Maintenance technicians and equipment rebuilders working on large-bore metric machinery need a seal that can handle heat, aggressive fluids, and continuous rotation without breaking down. Standard NBR seals often fall short in high-temperature or chemically demanding environments, leaving equipment vulnerable.

These FKM TC Oil Seals are made from FKM fluorine rubber — a fluoroelastomer engineered for demanding service conditions. Each seal follows the TC (double-lip) design: a primary sealing lip retains lubricant inside the housing while a secondary dust-exclusion lip blocks contaminants from entering. Available in metric sizes with an inner diameter (ID) range of 80mm–190mm (≈3.15"–7.48") and an outer diameter (OD) range of 105mm–220mm (≈4.13"–8.66"), with thickness from 8mm–18mm (≈0.31"–0.71"). Color is brown, consistent with standard FKM compound identification.

These fluorine rubber rotary shaft seals are well suited for industrial gearbox rebuilds, hydraulic pump maintenance, agricultural equipment overhauls, and heavy-duty electric motor servicing — anywhere a metric shaft seal rated for extreme temperatures and chemical exposure is required.

🔧 Compatibility: Designed for metric shaft and bore standards. Verify your shaft ID, housing OD, and depth before ordering. ID range: 80–190mm | OD range: 105–220mm | Thickness: 8–18mm.

✅ Key Features of These FKM TC Oil Seals

  • 🌡️ Wide Temperature Rating — Rated from -30°C to 250°C (-22°F to 482°F), these fluorine rubber rotary shaft seals maintain their sealing integrity in high-heat industrial environments where standard rubber compounds soften and fail.
  • 🛡️ Double-Lip TC Design — The dual-contact lip construction provides a primary oil-retention lip and a secondary dust-exclusion lip, reducing bearing contamination and extending service intervals on rotating equipment.
  • ⚗️ FKM Chemical Resistance — FKM fluoroelastomer resists petroleum oils, hydraulic fluids, fuels, and many industrial solvents — a significant advantage over NBR in chemically aggressive applications like hydraulic pump sealing.
  • 📐 Broad Metric Size Range — Covering ID 80mm–190mm and OD 105mm–220mm, this range addresses large-bore metric shaft sealing needs across gearboxes, motors, and agricultural machinery without requiring custom orders.
  • 💪 70 Shore Hardness — The 70 Shore A durometer rating balances flexibility for effective lip contact with enough firmness to resist extrusion under pressure, maintaining a reliable seal on rotating shafts.
  • ☀️ UV and Ozone Stable — FKM rubber resists UV radiation and ozone degradation, making these metric oil seals suitable for outdoor machinery and equipment operating in variable environmental conditions.

❓ Frequently Asked Questions

How do I choose the right size FKM TC oil seal?

Measure the shaft inner diameter (ID), the bore outer diameter (OD), and the housing depth (thickness) with calipers before ordering. This listing covers ID 80mm–190mm (≈3.15"–7.48") and OD 105mm–220mm (≈4.13"–8.66"). Select the variant that matches your shaft and housing dimensions exactly — a seal that is even 1mm off will not seat correctly. When in doubt, consult your equipment's service manual for the OEM seal part number and cross-reference the dimensions.

What temperature range can these FKM oil seals handle?

FKM (fluoroelastomer) rubber is rated for continuous service from -30°C (-22°F) to 250°C (482°F). This makes it suitable for high-heat applications such as industrial gearboxes, hydraulic pumps, and engine accessories where standard NBR seals would soften, swell, or crack. For intermittent peak temperatures, FKM generally tolerates brief excursions above 250°C, but continuous operation at the upper limit will reduce service life.

Are these oil seals resistant to chemicals and hydraulic fluids?

Yes. FKM fluorine rubber offers excellent resistance to petroleum-based oils, mineral hydraulic fluids, fuels, and many industrial solvents. It generally outperforms NBR and silicone rubber in aggressive chemical environments. For highly specialized fluids such as phosphate-ester hydraulic fluids or certain synthetic lubricants, verify compatibility with your fluid supplier before installation.

Can I use these seals outdoors or in wet environments?

FKM rubber has good UV and ozone resistance, making it suitable for outdoor machinery and equipment exposed to moisture and weathering. The TC double-lip design adds a secondary dust-exclusion lip that helps keep water and particulate contaminants out of the bearing housing, which is particularly useful in agricultural and construction equipment applications.

What does "TC" mean, and how does it differ from other seal types?

TC stands for double-contact lip seal. It features a primary sealing lip that retains lubricant inside the housing and a secondary lip that excludes dust and moisture from outside. This dual-lip construction is the most common configuration for rotary shaft sealing in industrial and automotive applications. Single-lip (SC) seals omit the secondary lip and are typically used where contamination ingress is not a concern.

What equipment are these metric oil seals compatible with?

These metric-dimensioned TC seals are generally compatible with industrial gearboxes, electric motors, hydraulic pumps, agricultural machinery (tractors, combines), and heavy construction equipment that use metric shaft and bore standards. Always verify the ID, OD, and thickness against your equipment's service manual or OEM seal specifications before installation to confirm fitment.

How do I install a large-diameter TC oil seal correctly?

Installation typically requires a seal driver or a flat press plate to push the seal squarely into the housing bore without cocking it. Lightly lubricate the outer diameter with clean oil before pressing in, and apply a thin film of grease to the sealing lip. Never hammer directly on the seal face. For seals in this size range (80–190mm ID), a hydraulic press is recommended for even, controlled seating. Ensure the seal is flush with or slightly below the housing face per your equipment's specification.
