XTO Oil Seal (TC / Skeleton Oil Seal) High Performance Rotary Shaft Seal

An XTO oil seal, commonly known as a TC or skeleton oil seal, is a precision-engineered rotary shaft sealing component designed to prevent leakage of lubricants such as oil and grease while effectively blocking dust, dirt, and moisture from entering the system.

These seals are widely used in automotive engines, motorcycle assemblies (crankshafts, wheel hubs), industrial gearboxes, and rotating machinery, where reliable sealing performance is essential for long-term durability and efficiency.

Key Features of XTO Oil Seals

Double-Lip Sealing Design

XTO oil seals feature a dual-lip structure:

• Primary sealing lip ensures effective oil and grease retention
• Secondary dust lip prevents external contaminants from entering

This design provides superior protection and extends equipment life.

Metal Reinforced Skeleton Structure

The seals are built with a strong internal metal case (TC/TG4 profile) that maintains shape stability and ensures proper fit inside the housing bore, even under high pressure and rotational stress.

Garter Spring Technology

A high-tension garter spring is integrated into the sealing lip to maintain consistent radial pressure against the rotating shaft, ensuring leak-free performance over time.

Material Options

NBR (Nitrile Rubber)

• Ideal for standard oil and grease applications
• Operating temperature range: -40C to 120C
• Excellent wear resistance and cost-effective performance

FKM (Viton / Fluororubber)

• Suitable for high-temperature and chemically aggressive environments
• Temperature resistance: up to 240C+
• High resistance to acids, fuels, and industrial chemicals

Standard Sizing Format

XTO oil seals are measured in a standard metric format:

Inner Diameter Outer Diameter Thickness (mm)

Example:
18 mm 30 mm 10 mm

Proper sizing is critical to ensure a perfect fit and optimal sealing performance.

How to Choose the Right Replacement Oil Seal

To select the correct XTO oil seal replacement, follow these steps:

• Measure the exact inner diameter, outer diameter, and thickness of the existing seal
• Check the OEM part number for your machine or vehicle
• Identify operating conditions such as temperature, pressure, and lubricant type
