  • ColorTransparent
  • Precision sealing with CRWA1 design
  • Nitrile rubber lips handle 10 psi pressure
  • Dual-lip construction resists oil and fuel
  • Carbon-steel spring maintains contact at 360 RPM
  • 5 in ID fits standard shaft sizes

Product Identity

The SKF 14846 shaft seal is a CRWA1-design rotary component built for 1.5 in shafts in a 2 in bore. It suits mechanics and engineers who need a reliable lip seal for rotating equipment in automotive or industrial maintenance.

Interface Limits

The nitrile rubber lips handle animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. Maximum pressure is 10 psi while the shaft runs up to 360 RPM at a surface speed of 6.74 mps.

Upgrade Context

This seal replaces worn CRWA1 units where the acrylic-coated case or carbon-steel spring has fatigued. The jump is worth it when the original lip material has hardened or the dual-lip geometry no longer excludes contamination.

Highlights

  • Precision sealing with CRWA1 design
  • Nitrile rubber lips handle 10 psi pressure
  • Dual-lip construction resists oil and fuel
  • Carbon-steel spring maintains contact at 360 RPM
  • 5 in ID fits standard shaft sizes

Questions about this item

Which SKF 14846 shaft seal dimensions match my application?

This seal has a 1.5 in inside diameter, 2 in outside diameter and .313 in overall width; verify those three measurements against your shaft and housing before ordering.

What does the 3,360 RPM limit mean once the seal is installed?

It is the maximum rotational speed the nitrile lips can sustain without overheating or losing contact; running faster risks premature wear or leakage.

How does the 10 psi pressure rating cap real-world use?

The seal is designed for low-pressure splash or vented environments up to 10 psi; pressurised systems exceeding that value will push fluid past the lips.
