SKF 27269 Rotary Shaft Seal

The SKF 27269 is a CRWA1-design rotary shaft seal built for inch-dimensioned equipment. It uses nitrile rubber lips and a carbon-steel spring to seal rotating shafts against common lubricants and fuels.

Verify shaft and housing dimensions before ordering

Confirm the shaft measures 2.75 in and the housing bore accepts 3.5 in outside diameter. The seal requires 0.375 in axial width and an acrylic-coated case. Ensure operating pressure stays at or below 10 psi and surface speed does not exceed 9.19 mps.

Suits maintenance on inch-series rotating equipment

This seal fits applications using animal or vegetable oils, diesel, gasoline, greases, hot water, light heating oil or mineral oils at speeds up to 2,520 RPM. It is not for metric-dimensioned shafts, pressures above 10 psi, or surface speeds exceeding 9.19 mps.

Questions about this item

Does the SKF 27269 shaft seal come with any installation tools or lubricant, or must those be purchased separately?

The box contains only the CRWA1 nitrile rubber seal with its carbon-steel spring and acrylic-coated case; no installation tools or lubricant are included.

Should I choose the 2.75 in inside diameter version or a different size for a 3.5 in bore?

This model is manufactured with a 2.75 in inside diameter and 3.5 in outside diameter, so it fits that bore directly; no other size variant is offered under part number 27269.

Will the 10 psi pressure rating and 520 RPM speed limit hold up on a diesel engine crankshaft?

The seal is rated for 10 psi maximum pressure and 520 RPM maximum rotational speed with a surface speed of 9.19 mps, suitable for diesel, gasoline, oil and grease applications within those limits.
