Rotary Shaft Seal for Industrial Use

The SKF 10123 is a CRW1 design rotary shaft seal built for machinery requiring reliable fluid containment. Its nitrile rubber lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. The single-lip construction with a carbon steel spring suits general industrial maintenance and repair tasks.

Capacity and Pressure Limits

The seal operates at a maximum pressure of 10 psi and a top rotational speed of 3,840 RPM. Surface speed reaches 5.09 mps before performance declines. It functions continuously up to 100 degrees C, providing headroom for typical engine and gearbox temperatures. Beyond these limits the lip material and spring tension cannot maintain a consistent seal.

Inch Measurement System Constraints

Manufactured to inch dimensions with a 1 in inside diameter, 2 in outside diameter and .25 in overall width, the seal fits only matching imperial shafts and bores. The acrylic case coating aids installation but does not alter the interference fit required. Metric equipment cannot use this component without custom adapters.

Questions about this item

Will the 1 in inside diameter match the shaft on my existing pump?

The seal is manufactured to a 1 in inside diameter and a 2 in outside diameter, so it fits shafts and bores machined to those dimensions.

How can I confirm the seal is seated correctly after installation?

After pressing the seal flush with the housing, the 0.25 in overall width should be fully visible and the spring-loaded lip must contact the shaft evenly around its circumference.

Does the package include any installation tools or lubricant?

The box contains only the CRW1 nitrile rubber shaft seal; installation tools and compatible lubricant must be purchased separately.
