TC Double Lip Oil Seal 35mm ID — Stop Leaks and Protect Your Rotary Shaft

Mechanics, equipment operators, and DIY repair enthusiasts know the frustration of a leaking rotary shaft seal — oil drips, contaminated bearings, and costly downtime. Whether you're servicing a gearbox, agricultural equipment, an ATV, or industrial machinery, a failed oil seal can sideline an entire job. These TC series double lip oil seals with a 35mm inner diameter are built to restore a reliable fluid barrier and keep your shaft running clean.

Each pack contains 20 individual TC oil seals. The seals feature an NBR (nitrile butadiene rubber) elastomeric lip bonded to a rigid steel skeleton for dimensional stability. The inner diameter is fixed at 35mm (≈1.378"), with outer diameter options ranging from 45mm (≈1.772") to 75mm (≈2.953") and thickness options from 5mm (≈0.197") to 12mm (≈0.472") — select the size that matches your housing bore and shaft groove from the variant dropdown above.

These TC double lip rotary shaft seals are well suited for gearbox output shaft sealing, agricultural PTO shaft applications, light industrial motor shaft sealing, and ATV or small engine crankshaft replacement — making them a practical stock item for any workshop that regularly services metric-dimensioned rotating equipment.

🔵 Compatibility Note: All variants share a 35mm inner diameter. Select your OD and thickness based on your housing bore and groove depth. Refer to your equipment service manual or measure the original seal before ordering.

✅ Key Features of These TC Double Lip NBR Oil Seals

🔩TC Double Lip Design — The secondary dust lip works alongside the primary sealing lip to block both fluid egress and external contaminant ingress, extending bearing and shaft life.
🧪NBR Elastomer Construction — Nitrile rubber resists petroleum-based oils, hydraulic fluids, diesel, and grease — the fluids most commonly encountered in rotary shaft seal applications.
🏗️Steel Skeleton Core — The rigid metal insert maintains the seal's round profile during press-fit installation and prevents distortion under operating loads.
📐23 Size Combinations Available — With OD options from 45mm to 75mm and thickness from 5mm to 12mm, this listing covers a wide range of metric rotary shaft seal replacements for a 35mm shaft.
📦20-Pack Value Quantity — Stocking 20 seals per order reduces per-unit cost and ensures you have spares ready for the next scheduled maintenance interval or unexpected field repair.
🌡️Broad Temperature Tolerance — NBR rubber typically performs reliably from approximately -40°F to +250°F (-40°C to +120°C), covering most standard mechanical operating environments.

❓ Frequently Asked Questions

How do I choose the right OD and thickness for my application?

Measure the bore (housing) diameter to determine the OD, and measure the shaft groove depth or housing depth to determine the thickness. All variants in this listing share a 35mm inner diameter. OD options range from 45mm (≈1.772") to 75mm (≈2.953") and thickness from 5mm (≈0.197") to 12mm (≈0.472"). When in doubt, consult your equipment's service manual or contact us to confirm.

What is the load or pressure rating of these oil seals?

TC series double lip seals are generally designed for low-to-medium pressure rotary shaft applications. They are not typically rated for high-pressure hydraulic systems. For specific pressure ratings, refer to your equipment specifications or contact us to confirm suitability.

Can these seals be used outdoors or in wet environments?

NBR rubber offers good resistance to water, oil, and mild weather exposure. However, for prolonged UV exposure or extreme outdoor conditions, a Viton or silicone seal may be more appropriate. These seals are generally suitable for enclosed or semi-exposed mechanical environments.

Are these seals compatible with metric shafts and housings?

Yes. All dimensions follow standard metric sizing (mm). The inner diameter is 35mm across all variants. These seals are compatible with any metric shaft and housing that matches the listed I.D. × O.D. × Thickness dimensions.

What fluids are NBR oil seals compatible with?

NBR (nitrile butadiene rubber) is generally compatible with petroleum-based oils, hydraulic fluids, diesel fuel, water, and many greases. It is not recommended for use with ketones, esters, or aromatic hydrocarbons. Always verify fluid compatibility with your specific application before installation.

Why buy a 20-pack instead of individual seals?

Seals are wear items that need periodic replacement. Having spares on hand reduces downtime during maintenance. A 20-pack is ideal for workshops, fleet maintenance operations, and repair shops that service multiple machines sharing the same 35mm shaft diameter.

What is the operating temperature range for these NBR seals?

NBR rubber typically performs reliably in a temperature range of approximately -40°F to +250°F (-40°C to +120°C). For applications exceeding this range, consider a high-temperature elastomer such as Viton (FKM).
