SKF 19938 HM14 shaft seal
The SKF 19938 is a rotary shaft seal built to the HM14 design code for grease-lubricated agricultural machinery. It fits a 2 in inside diameter and a 2.965 in outside diameter with a .5 in overall width. The single nitrile rubber lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. Buyers needing a double-lip seal or a different case coating should look elsewhere.
Sustained sealing at 2,409 RPM
Under continuous rotation the seal is rated for a maximum speed of 2,409 RPM and a pressure limit of 10 psi. The uncoated case and single contact lip maintain a steady barrier against the listed fluids without a spring load. Performance degrades if the shaft runs faster or pressure exceeds the rated value. Installations that demand higher pressure or speed ratings will require a different design.
2 in inside diameter decides fit
The 2 in inside diameter is the critical dimension that determines whether this seal matches the shaft. An incorrect bore size will cause immediate leakage or shaft damage regardless of the other specifications. Verify the shaft diameter before ordering.

Questions about this item
How much heat does the nitrile lip generate when the seal runs continuously at 2,409 RPM?
The seal is rated for a maximum rotational speed of 2,409 RPM and a pressure limit of 10 psi; heat rise depends on shaft finish, lubrication and ambient conditions rather than a fixed figure.
What shaft diameter and housing bore must already be present for the 2 in inside diameter and 2.965 in outside diameter to fit?
The seal requires a 2 in shaft and a 2.965 in bore; the .5 in width and single nitrile lip with no spring suit grease-lubricated agricultural machinery.
Will the HM14 nitrile lip withstand the same mineral oils and diesel that an older leather or felt seal handled?
The nitrile lip is compatible with mineral oils, diesel, gasoline, greases, animal and vegetable oils and hot water, so it directly replaces older seals in those fluids.
