Precision Engine Seal

The SKF 26123 rotary shaft seal fits shafts with a 2.625 in inside diameter and a 3.35 in outside diameter. Its CRW1 design code and single nitrile rubber lip suit maintenance on engines, pumps and gearboxes. Mechanics and rebuilders use it to retain lubricants and exclude dirt in standard inch-dimension housings.

Thermal and Pressure Limits

The nitrile rubber lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. Maximum pressure is rated at 10 psi while the maximum rotational speed reaches 2,580 RPM with a surface speed of 9 mps. An acrylic-coated case and carbon steel spring maintain consistent contact through normal temperature cycles.

Installed Function

The 0.375 in overall width seats directly into the bore without extra shims or spacers. The single lip and integral garter spring deliver immediate sealing action once pressed into place. No additional software, adhesives or special tools are required beyond standard press equipment.

Questions about this item

How do I install the SKF 26123 seal with its 2.625 in inside diameter and carbon steel spring, and what step is often missed?

Press the seal squarely into the bore until the acrylic-coated case seats fully; the step most often missed is lubricating the nitrile rubber lip with clean oil before installation to prevent dry-start damage.

What maintenance or replacement will the CRW1 design with its single nitrile lip need later?

Inspect the lip for hardening or wear at each oil change; replace the seal if leakage appears or the lip shows cracks, as the single-lip CRW1 design cannot be serviced separately.

At what limit does the 2,580 RPM maximum rotational speed show up first under sustained use?

The 2,580 RPM rating is the first limit reached; exceeding it raises lip temperature and wear rate, so keep shaft speed at or below this value for continuous operation.
