Shaft Seal 19607 Dimensions

The SKF 19607 rotary shaft seal fits a 1.969 in inside diameter and a 2.623 in outside diameter with a 0.313 in overall width. It is built for machinery that requires a CRWA1 design code and a two-lip contact seal arrangement. Mechanics working on engines or gearboxes using inch-system components will find this nitrile rubber seal matches the specified housing and shaft tolerances.

Sustained Operation at Speed and Pressure

Under continuous rotation the seal handles up to 3,000 RPM and a maximum surface speed of 7.84 mps while maintaining contact on both lips. The carbon steel garter spring keeps the lips loaded against the shaft even when the system runs at the 10 psi pressure limit for extended periods. Acrylic case coating resists the housing bore environment so the press fit remains stable during long duty cycles.

Fluid Compatibility and Speed Limits

The nitrile rubber lips are rated for mineral oils, gasoline, diesel, animal and vegetable oils, greases, light heating oil and hot water. Operation beyond the 7.84 mps surface speed or the 10 psi pressure ceiling is not supported by the material and spring design. Builders needing higher pressure tolerance or different fluid resistance must select an alternative seal profile.

Questions about this item

How much heat does the SKF 19607 generate when running continuously at 3,000 RPM?

The nitrile rubber lip and 10 psi pressure limit keep friction low, so heat build-up stays minimal during continuous operation at the rated 3,000 RPM and 7.84 m/s surface speed.

What shaft diameter and housing bore must I already have for this 1.969 in ID and 2.623 in OD seal to fit?

You need a shaft of 1.969 in and a housing bore of 2.623 in; the 0.313 in width and acrylic-coated case then seat correctly without extra machining.

Will the CRWA1 design and nitrile lips seal properly against the mineral oils and greases used in my older engine?

Yes, the dual-lip CRWA1 design with carbon-steel spring is rated for mineral oils, greases, gasoline and diesel, matching fluids common in older engines.
