SKF 14214 Rotary Shaft Seal

The SKF 14214 is a CRWA1-design rotary shaft seal built for 1.438 in inside diameter and 2.062 in outside diameter. It fits shafts requiring a 0.313 in overall width and dual-lip nitrile rubber contact. Mechanics and maintenance teams use it to retain lubricants and exclude contaminants in automotive and industrial equipment.

Thermals noise and power draw

The nitrile rubber lip material handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils. A carbon steel garter spring maintains consistent lip force. The acrylic case coating aids installation and resists corrosion. Maximum pressure is rated at 10 psi for low-pressure rotary applications.

Sustained load behaviour

Maximum rotational speed is 3,420 RPM with a maximum surface speed of 6.56 mps. The dual-lip design and spring-loaded contact maintain sealing integrity during continuous rotation within these limits. It is not suited for high-pressure systems or speeds exceeding the stated ratings.

Questions about this item

How do I install the SKF 14214 seal without damaging the 1.438 in shaft surface?

Press the 2.062 in outer case squarely into the housing using a driver that contacts only the metal case; never hammer the 0.313 in wide nitrile lips or the carbon-steel spring will deform and leak.

When should I plan to replace the nitrile rubber lips on this CRWA1 seal?

Replace the dual-lip assembly when the 10 psi pressure limit can no longer be held or when the lips harden from repeated exposure to gasoline, diesel, mineral oils, greases, or hot water.

At what shaft speed does the 6.56 mps surface-speed limit become the governing factor for this seal?

The 3,420 RPM ceiling is reached first; beyond that the 1.438 in shaft exceeds the 6.56 mps rating and lip temperature rises rapidly, causing premature nitrile wear.
