SKF 14262 Rotary Shaft Seal

The SKF 14262 is a CRW1 design rotary shaft seal built for automotive engine repair and maintenance. It fits shafts with a 1.438 in inside diameter and a 2.25 in outside diameter. Mechanics and DIYers use it to retain lubricants and exclude contaminants in rotating assemblies.

Critical dimension: 1.438 in inside diameter

This seal only works when the shaft measures exactly 1.438 in. The 2.25 in outside diameter and 0.313 in width must also match the housing bore and groove. Verify all three dimensions before ordering because an incorrect fit will leak immediately.

Suits repairs using NBR lips and inch-series bores

It handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils at up to 10 psi and 3,420 RPM. Builders needing higher pressure ratings, metric dimensions, double-lip designs or alternative lip materials should look at other sealing solutions.

Questions about this item

What does the 3,420 RPM limit mean once the seal is installed on a shaft?

The seal is rated for continuous operation up to 3,420 RPM; running the shaft faster can overheat the nitrile lip and shorten seal life.

How does the 10 psi pressure rating cap what the seal can handle in practice?

It is designed for low-pressure or vented housings up to 10 psi; higher system pressure will push the lip off the shaft and cause leakage.

What bore and shaft dimensions does the 1.438 in ID and 2.25 in OD require for proper fit?

The seal needs a 1.438 in shaft diameter and a 2.25 in housing bore; the 0.313 in width must match the gland depth.
