Product Identity

The SKF 19754 is a new rotary shaft seal built to the HM14 design code. It fits a two-inch shaft inside a 2.502-inch bore with a quarter-inch overall width. Mechanics and equipment owners use it to retain lubricant and exclude contamination on rotating shafts in agricultural machinery.

Pressure and Speed Envelope

The nitrile rubber lip handles a maximum of 10 psi and continuous speeds up to 2,970 RPM. The single-lip, springless construction relies on interference fit rather than spring load, so it is intended for grease-lubricated, low-pressure housings. Higher pressures or dry-running conditions exceed the design limits of this seal.

Installation Notes

Press the uncoated metal case squarely into the bore using a suitable driver; cocking the seal damages the nitrile lip and causes immediate leakage. Ensure the shaft surface is smooth, free of nicks and within the recommended finish range, because the single lip cannot compensate for rough or grooved journals. The seal is compatible with mineral oils, diesel, gasoline, greases, animal and vegetable oils, and hot water.

Questions about this item

Should I choose the HM14 nitrile seal or another design code for my 2 in shaft?

The HM14 design code with a single nitrile lip suits grease-lubricated agricultural machinery running on animal or vegetable oils, diesel, gasoline, greases, hot water, light heating oil or mineral oils.

What does the 2,970 RPM rating mean once the seal is installed?

It is the maximum rotational speed the seal can handle; running the shaft faster than 2,970 RPM risks premature lip wear and leakage.

How does the 10 psi pressure limit affect what I can seal?

The seal is rated for only 10 psi, so it suits low-pressure or splash-lubricated housings but not pressurised hydraulic circuits.
