TC Double Lip NBR Rubber Oil Seal Ring — Stop Leaks on Rotary Shafts from 100mm to 190mm

When a worn or incorrectly sized shaft seal lets oil weep past a gearbox, pump, or axle bearing, the mess is the least of your problems — contaminated lubricant and ingested grit accelerate wear fast. Mechanics, equipment rebuilders, and serious DIYers who work on industrial machinery, agricultural equipment, or heavy vehicles need a TC double lip NBR rubber oil seal ring they can trust to seat cleanly and hold.

Each seal in this listing is a TC-type skeleton oil seal with a steel-reinforced case and an NBR (nitrile butadiene rubber) sealing element. The size format is ID × OD × Width — for example, 120 × 150 × 12mm (≈4.72" × 5.91" × 0.47"). Inner diameters span 100mm to 190mm (≈3.94" to 7.48"), outer diameters from 120mm to 240mm, and widths from 10mm to 18mm, covering a wide range of metric shaft and housing combinations. Sold individually (1 pc per order).

Typical applications include gearbox output shaft sealing, hydraulic pump shaft seals, agricultural tractor axle seals, and industrial conveyor drive shaft sealing — anywhere a metric rotary shaft seal is needed to retain oil and exclude contaminants.

🔵 Compatibility Note: These are metric TC-type seals (ISO 6194 / DIN 3760). Match all three dimensions — ID, OD, and width — to your existing seal or housing drawing before ordering. Imperial (inch) sizes are not directly interchangeable.

✅ Key Features of These TC Double Lip NBR Rubber Oil Seal Rings

  • 🔩Steel-Reinforced Skeleton Case — The rigid metal insert maintains roundness under press-fit installation and prevents distortion in the housing bore, ensuring a consistent radial seal on rotary shafts.
  • 💧Double Lip (TC) Design — The primary lip retains lubricant; the secondary dust lip faces outward to block dirt, water, and debris — critical for gearbox shaft seals used in outdoor or agricultural equipment.
  • 🧪NBR Rubber Compound — Nitrile butadiene rubber resists petroleum oils, greases, and hydraulic fluids across a service range typically from -40°F to +212°F (-40°C to +100°C), covering most industrial and mobile equipment applications.
  • 📐Wide Size Range — ID 100mm to 190mm — Over 70 metric size combinations available in a single listing, from compact 100×120×12mm to large 190×240×18mm, reducing the need to source seals from multiple suppliers.
  • ⚙️Metric ISO / DIN Standard Dimensions — Sized to ISO 6194 / DIN 3760 conventions, making cross-referencing against OEM part numbers and seal catalogs straightforward for equipment rebuilds.
  • 🚚Ships from US Warehouse — Stocked domestically for faster delivery to US customers, avoiding the long lead times common with overseas-only suppliers of metric rotary shaft seals.

⚠️ Before You Order: Measure your existing seal or housing bore carefully. The size format is ID × OD × Width. A seal that is even 1–2mm off in OD will not press-fit correctly and may leak or fall out.

❓ Frequently Asked Questions

How do I choose the right oil seal size?

Measure the shaft diameter (ID), the bore diameter of the housing (OD), and the housing depth (width/thickness). The seal's ID must match the shaft diameter exactly for a leak-free fit. For example, a 120mm shaft needs a seal with a 120mm ID — that's approximately 4.72". Always verify all three dimensions before ordering. If you have the old seal, measure it directly or look for the size stamped on its face.

What load or pressure can these oil seals handle?

TC-type double lip oil seals are generally designed for low-to-medium pressure applications. They are typically rated for static pressures up to around 0.05 MPa (7 psi). For higher-pressure systems, a spring-loaded or PTFE-lip seal may be more appropriate. Contact us to confirm suitability for your specific application.

Are these seals suitable for outdoor or wet environments?

NBR rubber offers good resistance to petroleum-based oils, greases, and water splash. The double lip design adds a secondary dust/moisture exclusion lip, making these seals generally suitable for outdoor equipment and wet environments — including agricultural machinery and construction equipment. However, NBR is not recommended for prolonged exposure to ozone, strong acids, or ketone-based fluids.

What shaft or housing standards are these seals compatible with?

These are metric TC-type oil seals following ISO 6194 / DIN 3760 dimensions. They are compatible with metric shafts and housings. The size format is ID × OD × Width (e.g., 120 × 150 × 12mm). They are not directly interchangeable with imperial (inch) seals without verifying exact dimensions. Cross-reference against your OEM seal part number or housing drawing for confirmation.

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 housing using a seal driver or a flat press — never hammer directly on the seal face. The primary lip should face the fluid (oil) side. Avoid nicking the lip on shaft keyways or splines during installation. A chamfered shaft lead-in helps protect the lip.

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

A single lip seal retains lubricant on one side. A TC double lip seal adds a secondary lip that faces outward to exclude contaminants — dust, dirt, and moisture — from entering the bearing or gearbox. This makes TC seals the preferred choice for equipment operating in dirty, dusty, or wet conditions, such as agricultural tractors, construction machinery, and outdoor conveyor drives.

What temperature range can NBR oil seals withstand?

NBR rubber oil seals are generally rated for continuous service from approximately -40°F to +212°F (-40°C to +100°C), with short-term peaks up to around +248°F (+120°C). For higher-temperature applications such as engine crankshafts or turbocharger shafts, a Viton (FKM) seal is typically recommended instead.
