Shaft seal for rotating equipment
This SKF rotary shaft seal fits shafts with a 2.313 inch inside diameter and a 3.125 inch outside diameter. The CRW1 design uses a single nitrile rubber lip held by a carbon steel spring. It is built for engines and other machinery that need to retain lubricants or fluids.
Limits of the CRW1 design and NBR material
The seal handles a maximum pressure of 10 psi and a top rotational speed of 760 RPM. Surface speed must stay at or below 8.49 metres per second. Nitrile rubber resists mineral oils, diesel, gasoline, greases, animal and vegetable oils and hot water, but it is not rated for aggressive chemicals or extreme temperatures beyond the material range.
The 0.375 inch width decides fitment
Overall width is fixed at 0.375 inches, so the housing groove must match this dimension exactly. If the groove is wider or narrower the seal will not seat correctly and leakage will occur. Verify the groove width before ordering; no other dimension can compensate for a mismatch.

Questions about this item
Should I choose the 2.313 in inside diameter or the 3.125 in outside diameter version?
This seal has a single size: 2.313 in inside diameter, 3.125 in outside diameter and .375 in width. There are no alternative versions to select.
What does the 2760 RPM limit mean once the seal is installed in my engine?
The shaft must not exceed 2760 RPM, which corresponds to a surface speed of 8.49 mps; running faster risks lip wear and leakage.
What does the CRW1 design code cap in practice for pressure and speed?
CRW1 denotes a single-lip nitrile seal with a carbon-steel spring rated for 10 psi maximum pressure and 2760 RPM maximum rotational speed.
