What does the ID x OD x Thickness measurement mean?

ID = Inner Diameter (fits over the rotating shaft), OD = Outer Diameter (fits into the housing bore), and Thickness = the axial width of the seal. For example, 55*80*10mm means 55mm ID (≈2.165"), 80mm OD (≈3.150"), 10mm thick (≈0.394").

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

NBR (Nitrile Butadiene Rubber) offers good resistance to water, oils, and mild chemicals, making these seals suitable for general outdoor and wet environments. However, NBR is not recommended for prolonged exposure to ozone, UV, or aromatic fuels. For harsh outdoor conditions, consider FKM (Viton) alternatives.

Are these seals compatible with standard metric shaft and housing dimensions?

Yes. These TC skeleton oil seals follow standard metric dimensions and are generally interchangeable with seals from major manufacturers (SKF, FAG, NSK, etc.) of the same ID x OD x Thickness. Always verify the exact dimensions match your application.

What lubricants are compatible with NBR 70 oil seals?

NBR 70 is compatible with most petroleum-based oils, hydraulic fluids, gear oils, and greases. It is generally not compatible with synthetic esters, phosphate esters, or ketone-based fluids. When in doubt, check your fluid's compatibility with NBR before installation.

TC Oil Seal 55–58mm ID — Stop Shaft Leaks with a Reliable Rotary Shaft Seal

When a worn or missing shaft seal lets oil migrate past a rotating shaft, the result is contaminated bearings, damaged housings, and unplanned downtime. Mechanics, equipment technicians, and serious DIYers working on gearboxes, pumps, axles, and agricultural machinery need a seal that installs correctly and holds up under continuous rotation — not one that fails after a few hundred hours.

Each seal in this listing is a TC-type skeleton oil seal sold individually (1 PCS) or in a value pack (5 PCS). The inner diameter (ID) covers 55mm (≈2.165"), 56mm (≈2.205"), 57mm (≈2.244"), and 58mm (≈2.283"), with outer diameters ranging from 65mm up to 120mm and lip thicknesses from 5mm to 13mm — select the exact ID × OD × Thickness combination that matches your housing and shaft. The seal body is a carbon steel skeleton overmolded with NBR 70 (Nitrile Butadiene Rubber), and the dual-lip TC design adds a secondary dust-exclusion lip behind the primary oil-retention lip.

Typical applications include agricultural tractor PTO shafts and gearbox output shafts, industrial pump and motor shaft sealing, automotive differential and transfer-case rebuilds, and hydraulic cylinder rod sealing where a TC-type rotary shaft seal is specified. The wide size range makes this listing a practical single-source solution for shops that service multiple equipment lines.

🔵 Compatibility Note: These seals follow standard metric dimensions and are generally interchangeable with TC-type seals from SKF, FAG, NSK, and other major brands of the same ID × OD × Thickness. Always verify all three dimensions against your original seal or service manual before ordering.

⚠️ Size Confirmation: With 100+ size combinations available, please double-check your ID, OD, and thickness measurements before adding to cart. If you are unsure, contact us with your equipment make/model and we will help confirm the correct size.

✅ Key Features of These TC Rotary Shaft Oil Seals

🔩TC Dual-Lip Design — The primary lip retains oil and grease while the secondary dust lip blocks contaminants from entering the bearing cavity, extending bearing service life in dirty or wet environments.
🛡️NBR 70 Compound — Nitrile rubber with 70 Shore A hardness resists petroleum oils, hydraulic fluids, gear oils, and water — the standard choice for rotary shaft sealing in general industrial and agricultural equipment.
📐Wide Size Coverage — ID options of 55mm, 56mm, 57mm, and 58mm with OD from 65mm to 120mm and thickness from 5mm to 13mm cover a broad range of gearbox, pump, and axle shaft seal applications in a single listing.
⚙️Carbon Steel Skeleton — The rigid metal case maintains dimensional stability during press-fit installation and prevents the seal from distorting under housing bore pressure, ensuring consistent lip contact with the shaft.
📦Flexible Pack Quantities — Available as 1 PCS for a single repair or 5 PCS for maintenance kits and fleet servicing, with the multi-pack offering a lower per-unit cost for shops that service multiple units.
🚚Ships from US Warehouse — Stocked domestically for faster delivery to US customers, reducing wait times compared to overseas-only suppliers for common rotary shaft seal sizes.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size for my shaft?

Measure three dimensions: (1) your shaft's outer diameter — this is the seal's ID; (2) the bore diameter in the housing — this is the seal's OD; (3) the groove or housing depth — this determines the required thickness. For example, a 55mm shaft in an 80mm bore with a 10mm groove depth needs a 55×80×10mm seal. Always measure the original seal or consult your service manual rather than estimating by eye.

Quick inch conversions: 55mm ≈ 2.165", 56mm ≈ 2.205", 57mm ≈ 2.244", 58mm ≈ 2.283".

What does the ID × OD × Thickness format mean on the variant selector?

The three numbers represent: ID (Inner Diameter — fits over the rotating shaft), OD (Outer Diameter — presses into the housing bore), and Thickness (axial width of the seal). For example, "55*80*10mm" means 55mm ID (≈2.165"), 80mm OD (≈3.150"), 10mm thick (≈0.394"). All three must match your application exactly for a leak-free installation.

What shaft speed and pressure can these seals handle?

TC-type NBR oil seals are generally rated for low-to-medium pressure applications — typically up to 0.3 bar (4.4 psi). Shaft surface speed should generally not exceed 4–8 m/s for optimal lip life. These seals are not designed for high-pressure dynamic sealing. If your application involves higher speeds or pressures, contact us to confirm suitability before ordering.

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

NBR 70 offers good resistance to water, oils, and mild chemicals, making these seals suitable for general outdoor and wet environments — including agricultural equipment exposed to mud and moisture. The secondary dust lip on the TC design provides additional protection against ingress of dirt and water. However, NBR is not recommended for prolonged exposure to ozone, UV radiation, or aromatic fuels. For extreme outdoor or chemical environments, FKM (Viton) seals may be more appropriate.

Are these seals interchangeable with SKF, FAG, or NSK seals of the same size?

In most cases, yes. TC skeleton oil seals follow standardized metric dimensions, so a seal with the same ID × OD × Thickness is generally interchangeable with equivalent seals from SKF, FAG, NSK, Timken, and other major manufacturers. Always verify that the seal type (TC dual lip), dimensions, and material are compatible with your application before installation.

What oils and fluids are compatible with NBR 70 seals?

NBR 70 is compatible with most petroleum-based oils, mineral hydraulic fluids, gear oils, greases, and water. It is generally not compatible with synthetic esters (some PAO-based fluids), phosphate esters, ketone-based fluids, or concentrated acids. When in doubt, verify your specific fluid's compatibility with NBR rubber before installation.

Should I order the 1 PCS or 5 PCS option?

Order 1 PCS for a single repair or replacement job. The 5 PCS pack offers a lower per-unit cost and is ideal for maintenance kits, fleet servicing, or keeping spares on hand for equipment that uses the same seal size in multiple locations. Both options ship the identical seal — only the quantity differs.

How should I install a TC oil seal to avoid damaging the lip?

Clean the housing bore and shaft thoroughly before installation. Apply a thin film of clean oil or grease to the seal lip and shaft surface. 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. Avoid dragging the lip over sharp keyways or threads; use a protective sleeve if needed.
