22mm TC Oil Seal — Metric R23 NBR Rotary Shaft Seal for Reliable Leak Prevention

Leaking shaft seals are one of the most common causes of gearbox oil loss, pump failure, and contaminated bearings — and tracking down an exact metric replacement can eat up hours. Whether you're a maintenance technician rebuilding industrial equipment, a small-engine mechanic servicing agricultural machinery, or a DIYer fixing a leaking differential, having the right 22mm TC oil seal on hand makes the difference between a quick fix and a costly delay.

Each seal in this listing features a 22mm Inner Diameter (ID) and is available in a range of Outer Diameters (OD) from 28mm (≈1.10") to 45mm (≈1.77") and heights from 4mm (≈0.16") to 11mm (≈0.43"). The double-lip TC (R23) construction uses NBR (nitrile rubber) for the sealing element bonded to a steel outer case. Pack quantities range from 1 to 50 pieces per order — select the size and quantity combination that matches your job.

Typical applications include rotary shaft seals on gearboxes, hydraulic pumps, electric motors, agricultural equipment, and small engines — anywhere a 22mm shaft passes through a housing that must retain lubricant and exclude dust or moisture. The metric R23 TC profile is also widely used as a replacement seal in compressors, conveyor drives, and marine outboard lower units.

🔵 Compatibility Note: These seals fit any 22mm nominal shaft diameter. Match the Outer Diameter (OD) to your housing bore and the Height to your groove depth. Sizes listed as ID × OD × Height (all in mm). If you are unsure of your housing dimensions, measure with calipers before ordering.

✅ Key Features of These 22mm TC Rotary Shaft Oil Seals

🔒Double-Lip TC (R23) Design — Primary sealing lip retains lubricant while the secondary dust lip blocks contaminants, making this arrangement more effective than single-lip seals in dirty or wet environments.
🧱NBR Nitrile Rubber Construction — Nitrile compound resists petroleum-based oils, greases, water, and mild fuels across a working temperature range typically from −40°F to +250°F (−40°C to +121°C).
⚙️Steel-Reinforced Outer Case — The rigid metal shell provides a secure press-fit into the housing bore, maintaining concentricity and preventing the seal from spinning or walking out under vibration.
📐Wide Size Selection — 22mm ID, Multiple OD & Heights — OD options from 28mm to 45mm and heights from 4mm to 11mm cover a broad range of housing configurations without needing custom seals.
📦Flexible Pack Quantities (1–50 Pcs) — Order a single seal for a one-off repair or stock up with a 25- or 50-piece pack for fleet maintenance — larger packs reduce per-unit cost for high-volume users.
🔄Metric R23 / ISO 6194-1 Standard Profile — Conforms to the internationally recognized TC seal standard, making these direct replacements for OEM seals in European, Asian, and metric-spec machinery.

⚠️ Before ordering: Measure your shaft OD, housing bore, and groove depth with calipers. The ID (22mm) must match your shaft; the OD must match your housing bore; the height must fit your groove. When in doubt, contact us to confirm before purchasing.

❓ Frequently Asked Questions

How do I choose the right TC oil seal size?

Match the Inner Diameter (ID) to your shaft diameter, the Outer Diameter (OD) to your housing bore, and the Height to the groove depth. All seals here share a 22mm ID. For example, a 22 × 32 × 7mm seal fits a 22mm shaft in a 32mm bore with a 7mm groove. Convert mm to inches by dividing by 25.4 — so 32mm ≈ 1.26".

What does TC lip arrangement mean?

TC (also written R23) is a double-lip design: a primary sealing lip retains lubricant and a secondary dust lip excludes contaminants. This arrangement is generally preferred over single-lip (SC/R21) seals in applications where both oil retention and dirt exclusion are needed.

What is the load or pressure rating of these seals?

TC-type rotary shaft seals are typically rated for low-to-moderate pressure applications — generally up to about 0.3 bar (4.4 psi) of differential pressure. For higher-pressure systems, a pressurized or PTFE-lip seal is typically required. Contact us to confirm suitability for your application.

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

NBR (nitrile rubber) offers good resistance to petroleum-based oils, water, and mild weather exposure. It is generally suitable for outdoor use in moderate climates. For extreme UV, ozone, or chemical exposure, a Viton (FKM) seal is typically recommended instead.

What shaft or housing standards are these seals compatible with?

These are metric seals conforming to the R23/TC standard (ISO 6194-1 equivalent). They fit any 22mm nominal shaft diameter regardless of thread standard — the seal contacts the shaft OD, not the thread. Verify your housing bore matches the seal OD before ordering.

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 flat plate — never hammer directly on the seal face. The primary lip should face the oil side. Avoid nicking the lip on shaft keyways or threads during installation.

How many seals come in each order?

Pack quantity is selectable at checkout: 1, 2, 5, 10, 15, 20, 25, or 50 pieces depending on the size chosen. Larger packs offer a lower per-unit cost and are ideal for maintenance stock or fleet repairs.
