SKF 15592 Rotary Shaft Seal

The SKF 15592 is a CRW1-design rotary shaft seal built for automotive engine maintenance. It suits mechanics and vehicle owners replacing worn seals on shafts with a 1.563 in inside diameter and 2.437 in outside diameter. The nitrile rubber lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils.

Installation notes and common issues

Press the seal squarely into the housing using a driver that contacts the outer case only; the acrylic coating helps prevent bore damage during fitting. The carbon-steel spring keeps the single lip loaded against the shaft. Misalignment or a rough shaft surface often causes early leakage, and exceeding 3,300 RPM or 6.9 mps surface speed will overheat the lip.

Pre-order checks

Verify the shaft diameter matches the 1.563 in inside diameter and the housing bore matches the 2.437 in outside diameter. Confirm the operating fluid is listed among the compatible types and that system pressure stays below 10 psi. Ensure the shaft surface finish and hardness meet general seal requirements so the nitrile lip can seat correctly.

Questions about this item

How can I confirm the seal is seated correctly after installation?

Check that the 1.563 in inside diameter fits the shaft snugly and the 2.437 in outside diameter sits flush in the housing; the single nitrile lip should show even contact all round.

What comes in the box and what must I source separately?

The box contains the SKF 15592 CRW1 shaft seal only; you will need to supply the shaft, housing, and any installation tools or lubricant yourself.

Which dimensions should I match when choosing this seal?

Select the 15592 when your application calls for a 1.563 in shaft diameter, 2.437 in bore diameter and 0.313 in width with a single-lip nitrile design rated to 10 psi and 3,300 RPM.
