Comprehensive Guide to Cross-Referencing Oil Seals: National, SKF, and CR Options

When it comes to machinery and automotive applications, ensuring the compatibility of oil seals is critical. Choosing the right seal not only protects equipment from contaminants but also maintains optimal performance. Cross-referencing oil seals helps identify equivalent seals from different brands, such as National, SKF, and CR, based on dimensions, part numbers, or applications. This article delves into cross-referencing solutions, focusing on crankshaft oil seals and offering practical tools for finding the right match.

What Is Oil Seal Cross-Referencing?

Oil seal cross-referencing involves matching a seal from one manufacturer with equivalent products from others. This is essential when replacing hard-to-find or obsolete seals. Tools such as online cross-reference charts, part number lookups, and catalogs simplify this process. Common platforms include:

• National Oil Seal Cross-Reference to SKF
• CR Oil Seal Cross-Reference by Part Number
• Online Oil Seal Cross-Reference Charts

These tools enable users to identify seals like the CR Oil Seal 12350 or National Oil Seal Front Crankshaft Oil Seal and locate compatible options from other manufacturers.

Key Features of Crankshaft Oil Seals

Crankshaft oil seals, whether for the front or rear, are designed to prevent oil leakage and contamination around the crankshaft. Popular options include:

• Front Crankshaft Oil Seal: Installed near the timing cover, commonly referenced by part numbers like CR Oil Seal 12364 or National Oil Seal Crankshaft Front.
• Rear Crankshaft Oil Seal: Positioned between the engine and transmission, often requiring specific material compatibility due to high pressure and temperature conditions.

When cross-referencing crankshaft seals, tools like SKF Oil Seal Cross-Reference by Part Number or CR Oil Seal Size Charts are indispensable.
