Precision Rotary Shaft Seal for Industrial Equipment

The SKF 16201 rotary shaft seal fits a 1.625 inch shaft and a 2.441 inch bore with a 0.313 inch width. It uses a CRWA1 design code with two nitrile rubber lips and a carbon steel spring. The seal handles fluids such as mineral oils, gasoline, diesel, greases and hot water.

Acrylic-Coated Case Resists Installation Damage

An acrylic coating on the metal case protects against corrosion and eases press-fitting into the housing bore. The contact-type lip design maintains sealing at pressures up to 10 psi and surface speeds of 7.06 mps. Maximum rotational speed reaches 3,240 RPM for continuous operation.

Ready-to-Install Replacement Component

Supplied as a single new unit, the seal requires no additional tools, lubricants or software for fitting. The transparent nitrile material allows visual inspection of lip condition before installation. Mechanics and maintenance teams can replace worn seals directly to restore fluid containment.

Questions about this item

What pressure does the CRWA1 seal design handle in practice?

The CRWA1 design is rated for a maximum of 10 psi in service.

What shaft and bore diameters does the 16201 seal require to fit?

It fits a 1.625 in shaft inside a 2.441 in bore with a .313 in overall width.

How is the NBR lip seal installed and which step is often missed?

Press the seal squarely into the bore until flush, lubricating the lips first; the step often missed is pre-lubrication to prevent dry-start damage.
