SKF 9960 Rotary Shaft Seal
The SKF 9960 is a CRW1-design rotary shaft seal built for automotive and industrial maintenance. It fits shafts with a 1 in inside diameter and a 1.686 in outside diameter. Mechanics and engineers use it to retain lubricants and exclude contaminants in rotating equipment.
10 psi maximum pressure rating
This seal is rated for a maximum pressure of 10 psi, which determines its suitability for low-pressure sealing tasks. Exceeding this limit can cause leakage or lip failure. Verify your system pressure before installation to ensure reliable performance.
Nitrile lip with carbon-steel spring
The single nitrile rubber lip resists animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. A carbon-steel garter spring maintains consistent lip contact up to 3,840 RPM and 5.09 mps surface speed. The acrylic-coated case aids installation and corrosion resistance.

Questions about this item
How does the 3,840 RPM limit affect daily use?
The seal is rated for continuous operation up to 3,840 RPM. Above that speed the lip may overheat and wear prematurely, so match the shaft speed to this ceiling.
What does the 10 psi pressure rating mean for sealing performance?
The seal handles up to 10 psi differential pressure. Higher system pressure can push the lip off the shaft, causing leakage.
Will the 1.686 in outside diameter and 0.25 in width fit my housing?
The seal needs a bore of 1.686 in and a 0.25 in wide groove. Verify both dimensions before installation.
