TC Double Lip Oil Shaft Seal with Spring — Stop Leaks & Block Contaminants

When a worn or incorrectly sized shaft seal lets oil weep past a gearbox, pump, or axle housing, the mess is the least of your problems — bearing failure and costly downtime follow quickly. Mechanics, equipment rebuilders, and serious DIYers who work on agricultural machinery, industrial drives, or automotive differentials need a reliable TC double lip oil shaft seal that seats correctly and holds under real operating conditions.

Each seal in this listing is a metric TC (double lip with garter spring) design made from NBR (nitrile rubber) with a steel outer case. Sizes span ID 60–80mm, OD 80–125mm (≈3.15–4.92"), and widths of 8mm (≈5/16"), 10mm (≈3/8"), or 12mm (≈15/32") — select the exact ID × OD × Width combination from the variant dropdown. Available in single-piece, 2-pack, 4-pack, and 10-pack quantities to suit one-off repairs or workshop stock.

Typical applications include gearbox output shaft sealing, hydraulic pump shaft retention, electric motor end-cap sealing, and agricultural PTO shaft assemblies — anywhere a rotating shaft passes through a stationary housing and must retain lubricant while excluding dust, dirt, and moisture.

🔵 Compatibility check: Match all three dimensions — ID (shaft diameter), OD (housing bore), and Width (housing depth) — before ordering. Variants are listed as ID × OD × Width in millimeters. If your housing uses inch dimensions, convert: 1 inch = 25.4mm.
⚠️ Confirm your measurements: Oil seal sizing is exact. A seal that is 1–2mm off in any dimension will not seal correctly. If you are unsure of your housing dimensions, measure with calipers before selecting a variant or contact us to confirm.

✅ Key Features of These TC Double Lip Oil Shaft Seals

  • 🔩Double Lip TC Design — The primary lip retains oil and grease while the secondary dust lip blocks dirt, debris, and moisture from reaching the bearing — a critical advantage in agricultural and outdoor equipment shaft sealing.
  • 🌀Garter Spring Loaded — An internal garter spring maintains consistent radial lip pressure against the shaft as the seal lip wears, extending service life compared to springless single-lip designs.
  • 🧱NBR Nitrile Rubber Body — NBR offers broad compatibility with petroleum-based oils, gear lubricants, hydraulic fluids, and water — the go-to material for gearbox and axle shaft seal replacements.
  • 🔧Steel Outer Case — The rigid steel shell provides a firm press-fit into the housing bore, resisting blowout under pressure and ensuring the seal stays centered during operation.
  • 📐Wide Metric Size Range — ID 60–80mm, OD 80–125mm, widths 8/10/12mm covers a broad range of metric shaft seal replacements for European and Asian machinery, pumps, and motors.
  • 📦Flexible Pack Quantities — Order 1, 2, 4, or 10 seals per transaction — ideal for single repairs, matched-axle pairs, or stocking a workshop with metric oil shaft seal inventory.

❓ Frequently Asked Questions

How do I choose the right size TC oil seal?

Measure the shaft inner diameter (ID), the housing bore outer diameter (OD), and the housing depth (width). Match all three dimensions to the variant listed as ID × OD × Width. For example, a 70×95×10mm seal fits a 70mm shaft, 95mm bore, and 10mm housing depth. When in doubt, measure twice — a seal that is even 1mm off will not seat correctly.

What does the TC designation mean on an oil seal?

TC stands for double lip with a garter spring. The primary lip retains oil or grease, while the secondary dust lip blocks contaminants from entering. The internal spring keeps constant radial pressure on the shaft, maintaining the seal even as the lip wears over time.

What is the temperature and pressure range for these NBR seals?

NBR (nitrile rubber) generally handles temperatures from approximately -40°F to +250°F (-40°C to +120°C) and is suited for low-to-moderate pressure applications. It is not recommended for use with phosphate ester fluids or ketones. For high-heat environments, consider a Viton (FKM) alternative.

Are these seals suitable for outdoor or wet environments?

NBR has good resistance to water, petroleum-based oils, and mild hydraulic fluids, making it generally suitable for outdoor equipment and wet conditions. However, prolonged exposure to ozone, UV, or aromatic solvents can degrade the rubber over time. For extreme outdoor exposure, a seal with an additional protective cover lip is typically recommended.

What shaft surface finish is recommended for TC oil seals?

For best sealing performance, the shaft surface in contact with the seal lip should generally have a finish of Ra 0.2–0.8 µm (approximately 8–32 µin). A shaft that is too rough will accelerate lip wear; one that is too smooth may not retain a thin lubricant film. Hardened shafts (typically 45–65 HRC) are recommended to minimize wear.

Can I use these seals in gearboxes, pumps, or axle applications?

Yes. TC double lip oil seals are commonly used in gearboxes, hydraulic pumps, electric motors, agricultural equipment, and automotive axle/differential housings. The specific size must match your application's shaft and bore dimensions. If you are unsure, contact us to confirm compatibility before ordering.

How do I install a TC oil seal without damaging it?

Apply a thin film of clean grease or the retained fluid to the seal lip before installation. Use a seal driver or a flat press plate to push the seal in squarely — never hammer directly on the seal face. Press until the seal is flush with or just below the housing surface. Avoid dragging the lip over sharp keyways or threads; use a sleeve or tape to protect the lip during installation.
