Shaft Seal CRW1 Design

The SKF 10049 is a new rotary shaft seal built to the CRW1 design code with a single nitrile rubber lip and carbon steel spring. It suits automotive and industrial equipment where a compact inch-dimension seal is specified for rotating shafts.

Fits 1 in Shafts

This seal mounts on a 1 in inside diameter shaft and seats into a 1.828 in bore with a .25 in overall width. The acrylic-coated case resists corrosion while the nitrile lip handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils up to 10 psi. It operates at speeds up to 3,840 RPM and 5.09 mps surface speed without additional retention hardware.

For Standard Rotary Sealing

Mechanics and maintenance teams needing a CRW1 nitrile seal for common fluid types and moderate speeds will find this part fits directly. Buyers who require higher pressure ratings, multiple sealing lips, alternative lip materials or metric dimensions should look at something else.

Questions about this item

What is the maximum rotational speed before the seal lip overheats?

The seal is rated for 3,840 RPM, which corresponds to a maximum surface speed of 5.09 m/s.

How much heat does the seal generate during continuous operation?

The nitrile lip running at 5.09 m/s surface speed produces frictional heat; ensure adequate lubrication and shaft finish to manage temperature rise.

What shaft diameter and surface finish are required for this seal to function?

The seal fits a 1 in shaft; the case has an acrylic coating and the carbon-steel garter spring maintains lip contact at up to 10 psi.
