SKF 19768 Nitrile Shaft Seal
The SKF 19768 is a nitrile rotary shaft seal built to the HM14 design code. It fits a two-inch shaft inside a 2.625-inch bore with an overall width of .234 inches. Mechanics and plant technicians use it to retain lubricant and exclude contaminants on rotating equipment.
Press-fit installation demands clean surfaces
Press the uncoated case squarely into the housing using a driver that contacts the outer edge only. A cocked start or a burred bore will distort the single nitrile lip and cause immediate leakage. Light oil on the lip eases entry and protects the sealing edge during the first rotation.
Suits low-pressure rotary shafts up to 10 psi
This seal handles surface speeds to 999 mps in standard inch-dimensioned gearboxes, pumps and motors. Buyers needing higher pressure ratings, dual-lip redundancy or a coated case for corrosion resistance should look at alternative designs.

Questions about this item
How do I confirm the 19768 shaft seal is seated correctly after installation?
After pressing the uncoated case into the bore, verify the nitrile lip sits evenly against the 2 in shaft with no visible gaps; the single dual-lip design should show uniform contact around the full circumference.
What comes with the SKF 19768 seal and what must I source separately?
The box contains one HM14 rotary shaft seal measuring 2 x 2.625 x .234 in; you will need to supply the correct installation driver or sleeve and any shaft-surface preparation materials.
Which HM14 nitrile seal dimensions match a 2 in shaft and 2.625 in bore?
Choose the 19768 variant — its 2 in inside diameter, 2.625 in outside diameter and 15/64 in width are the only combination in this series that fits those exact shaft and bore sizes.
