TC Skeleton Oil Seal 22mm ID — Stop Leaks and Keep Contaminants Out

If you're dealing with grease leaking past a worn shaft seal, or grit working its way into a bearing housing, a reliable rotary shaft seal is the fix. These TC skeleton oil seals are built for mechanics, equipment technicians, and serious DIYers who need a dependable metric seal that fits right and lasts.

Each seal features a 22mm (≈7/8") inner diameter with outer diameters ranging from 32mm (≈1-1/4") to 52mm (≈2"), and heights of either 7mm (≈9/32") or 10mm (≈3/8"). The construction combines an NBR 70 nitrile rubber body with a rigid metal skeleton frame and an internal garter spring — the spring keeps constant radial pressure on the shaft for a consistent, leak-free seal. Available in quantities of 1, 2, 5, or 20 pieces.

These seals are well-suited for automotive gearboxes, small engine crankshafts, agricultural equipment axles, and general industrial machinery where a metric double-lip rotary shaft seal is required. The double-lip TC design is the go-to choice for applications exposed to both lubricant retention and external contamination.

ℹ️ Compatibility Note: These seals have a fixed 22mm inner diameter. Select your OD and height from the variant options to match your housing bore and axial space. Refer to your equipment manual or measure your existing seal before ordering.

✅ Key Features of These TC Skeleton Oil Seals

🔩Double-Lip TC Design — The primary lip retains lubricant while the secondary dust lip blocks dirt, debris, and moisture — ideal for double lip rotary shaft seal applications in dirty or wet environments.
🌡️NBR 70 Nitrile Rubber — Resists petroleum-based oils, greases, and water across a wide temperature range (typically -40°F to +250°F), making it a reliable nitrile rubber oil seal for most automotive and industrial fluids.
🏗️Rigid Metal Skeleton Frame — The embedded steel case maintains the seal's round shape during press-fit installation and prevents distortion under operating loads.
🔄Garter Spring Loaded Lip — An internal coil spring applies consistent radial force against the shaft, compensating for minor shaft runout and maintaining sealing contact over time.
📐Multiple OD Options (32–52mm) — Nine size combinations with ODs from 32mm to 52mm let you find the exact metric skeleton oil seal that matches your housing bore without modification.
📦Flexible Pack Quantities — Order 1, 2, 5, or 20 pieces — whether you need a single replacement seal or a shop stock of TC oil seals for ongoing maintenance.

❓ Frequently Asked Questions

How do I choose the right OD and height for my application?

Match the ID (22mm / ≈7/8") to your shaft diameter and the OD to your housing bore. Heights of 7mm (≈9/32") and 10mm (≈3/8") are available — choose based on the axial space in your housing. When in doubt, measure the old seal or consult your equipment manual. A seal that is too tall will not seat flush; one that is too short may not seal properly.

What load or pressure can these seals handle?

TC skeleton oil seals are generally designed for low-to-moderate pressure applications (typically up to 0.05 MPa / ~7 psi). They are not intended for high-pressure hydraulic systems. For pressurized applications, a different seal type — such as a lip seal with a backup ring — is recommended.

Can these seals be used outdoors or in wet environments?

NBR (Nitrile) rubber offers good resistance to water, oil, and grease, making it suitable for many outdoor and wet environments. However, NBR is generally not recommended for prolonged exposure to ozone, UV radiation, or aromatic/halogenated fuels. For harsh outdoor or chemical environments, a VITON (FKM) seal may be a better fit.

What shaft and housing standards are these compatible with?

These TC-type seals follow metric dimensions and are generally compatible with ISO 6194 / DIN 3760 standard housings. The TC designation indicates a double-lip design with a metal outer case. Always verify the ID, OD, and height against your equipment specs before ordering to ensure a proper press fit.

What temperature range can NBR seals withstand?

NBR rubber typically performs well in temperatures ranging from approximately -40°F to +250°F (-40°C to +120°C). Sustained exposure above this range may cause premature hardening, cracking, or seal failure. If your application runs hotter, consider a silicone or VITON seal instead.

What is the difference between a single-lip and double-lip (TC) oil seal?

A single-lip seal retains lubricant on one side only. A double-lip TC seal adds a secondary dust lip that faces outward, blocking contaminants like dirt, grit, and moisture from entering the bearing or housing. This makes the TC double lip rotary shaft seal the preferred choice for most automotive, agricultural, and general machinery applications where both retention and exclusion are needed.

How do I install a TC skeleton oil seal correctly?

Clean the housing bore and shaft thoroughly. Apply a thin film of clean grease to the seal lip and the housing bore. Press the seal in squarely using a seal driver or a flat block — never hammer directly on the seal face, as this can distort the metal case. Ensure the primary lip faces the lubricant side (inward). Do not over-drive the seal past flush.
