SKF 17523 Rotary Shaft Seal

This SKF rotary shaft seal is designed for engine and machinery applications where a reliable fluid barrier is required. It fits assemblies needing a 1.75 in inside diameter and 2.75 in outside diameter. The nitrile rubber lips handle animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils.

Critical Dimensions and Speed Rating

The seal has an overall width of .313 in and a maximum rotational speed of 3, 180 RPM with a surface speed of 7.36 mps. These figures determine whether the seal matches the shaft geometry and operating speed of the specific repair or rebuild job.

Suitable for Standard Oil and Grease Sealing

Mechanics sealing crankshafts, gearboxes or pump shafts against common lubricants at moderate speeds will find this CRWA1 design appropriate. It is not suited for systems exceeding 10 psi pressure or for fluids and temperatures outside the listed compatibility range. Buyers needing higher pressure tolerance or different chemical resistance should verify alternative specifications.

Questions about this item

What does the 1.75 in inside diameter mean for shaft fit?

The 1.75 in inside diameter matches a 1.75 in shaft so the seal sits directly on the journal without an adapter.

How does the 10 psi pressure limit affect sealing performance?

The 10 psi maximum pressure rating means the CRWA1 design handles only low-pressure splash or gravity-fed systems, not pressurised circuits.

What space does the .313 in overall width need in the housing?

The .313 in overall width requires a matching groove depth and at least that much axial room in the bore for the carbon-steel spring and dual NBR lips to seat fully.
