Metric TC Double Lip NBR Oil Seal — 60mm & 63mm Inner Diameter Rotary Shaft Seal

A leaking rotary shaft seal is one of the most common causes of gearbox oil loss, bearing contamination, and premature drivetrain failure — yet finding the exact metric replacement can take hours of cross-referencing catalogs. Whether you're a professional mechanic, a machine shop technician, or a hands-on DIYer rebuilding agricultural equipment, this TC double lip NBR oil seal gives you a direct metric replacement without the guesswork.

Each seal follows the R23 / TC lip arrangement per ISO 6194, featuring a steel-reinforced outer case and a nitrile rubber (NBR) sealing element. Available in 60mm and 63mm inner diameters, with outer diameters ranging from 74mm (≈2.91") to 130mm (≈5.12") and heights from 5mm (≈0.20") to 13mm (≈0.51"). Select your exact ID × OD × Height combination from the variant dropdown, and choose a pack of 1, 2, 3, 5, or 10 pieces to match your job quantity.

These rotary shaft seals are widely used in gearbox and transmission rebuilds, agricultural machinery and tractor axle service, and industrial motor and pump shaft sealing — anywhere a metric TC oil seal is called for to retain lubricant and exclude contaminants from a rotating shaft.

ℹ️ Compatibility Note: These seals conform to the metric TC (R23) standard per ISO 6194. Always verify your shaft ID, housing bore OD, and housing depth before ordering. Dimensions are listed as ID × OD × Height (mm). If your equipment uses inch-standard seals, use the conversion: 1 inch = 25.4 mm.

✅ Key Features of These Metric TC Double Lip NBR Oil Seals

  • 🔒TC Double Lip Design (R23) — The primary sealing lip retains lubricant while the secondary dust lip blocks dirt, water, and debris, making this rotary shaft seal suitable for contaminated environments.
  • 🧲Steel-Reinforced Outer Case — A rigid metal shell ensures the seal presses firmly and squarely into the housing bore, maintaining concentricity and preventing blowout under normal operating pressure.
  • 🌡️NBR Rubber Sealing Element — Nitrile rubber provides reliable resistance to petroleum-based oils, gear lubricants, and greases across a typical service range of approximately -40°F to +250°F (-40°C to +120°C).
  • 📐Wide Metric Size Range — With 60mm and 63mm inner diameters and OD options from 74mm to 130mm, this listing covers a broad range of metric gearbox oil seal and shaft seal applications in a single product family.
  • 📦Flexible Pack Quantities — Order 1 piece for a single repair or up to 10 pieces for fleet maintenance or workshop stock — each pack is priced to reflect the quantity, so you only buy what you need.
  • 🔧Direct Metric Replacement — Designed to ISO 6194 TC (R23) dimensional standards, these seals cross-reference directly to OEM metric shaft seal specifications on tractors, industrial gearboxes, and rotating machinery.

❓ Frequently Asked Questions

How do I choose the right oil seal size?

Measure the shaft diameter (inner diameter / ID), the bore diameter in the housing (outer diameter / OD), and the housing depth (height/width). Match all three dimensions to the variant listed as ID × OD × Height. For example, a 60 × 90 × 10mm seal fits a 60mm shaft, a 90mm bore, and a 10mm deep housing. When in doubt, measure twice and consult your equipment manual.

What does TC lip arrangement mean?

TC (also written as R23 per ISO 6194) refers to a double-lip seal design. The primary lip retains lubricant and excludes contaminants, while the secondary dust lip provides an additional barrier against dirt, water, and debris. This dual-lip configuration is generally preferred over single-lip (SC) seals in applications exposed to contamination.

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

NBR (nitrile rubber) oil seals typically operate in a temperature range of approximately -40°F to +250°F (-40°C to +120°C) and are generally rated for low-pressure applications (typically under 7 psi / 0.5 bar of shaft-side pressure). For high-temperature or high-pressure environments, consider FKM (Viton) seals instead.

Are these oil seals suitable for outdoor or wet environments?

NBR rubber offers good resistance to petroleum-based oils, greases, and water splash. The TC double-lip design adds an extra layer of protection against moisture and dirt ingress. However, NBR is not recommended for prolonged immersion or exposure to ozone, strong acids, or ketone-based fluids. For fully submerged or chemically aggressive environments, consult a seal specialist.

What shaft speed can these rotary shaft seals handle?

Rotary shaft seals of this type generally support shaft surface speeds up to approximately 4–6 m/s (800–1,200 ft/min) under normal lubricated conditions. Actual limits depend on shaft finish, lubricant viscosity, and operating temperature. A smooth shaft surface (typically Ra 0.2–0.8 µm) is recommended for optimal seal life.

What fluids are compatible with NBR oil seals?

NBR seals are generally compatible with mineral oils, hydraulic fluids (petroleum-based), gear oils, greases, water, and diesel fuel. They are not compatible with aromatic hydrocarbons, chlorinated solvents, brake fluids (glycol-based), or phosphate ester hydraulic fluids. Always verify compatibility with your specific fluid before installation.

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 a flat plate — never hammer directly on the seal face. The seal should sit flush with or slightly below the housing face. Ensure the primary lip faces the lubricant side (inward) and the dust lip faces outward.

How do I convert the seal dimensions from mm to inches?

Divide millimeters by 25.4 to get inches. Quick reference: 60mm ID ≈ 2.362" | 63mm ID ≈ 2.480" | 90mm OD ≈ 3.543" | 10mm height ≈ 0.394". Use these conversions when cross-referencing with inch-standard parts catalogs.
