SKF 12614 Rotary Shaft Seal

This SKF 12614 rotary shaft seal fits shafts with a 1.25 in inside diameter and a 2.374 in outside diameter. It is designed for automotive engine sealing where a CRWA1 design is specified. The seal handles fluids such as mineral oils, gasoline, diesel, greases and hot water. Mechanics and engine rebuilders use it to prevent leakage at rotating shafts.

Installation notes and common issues

Press the seal squarely into the bore using a driver that contacts the outer case only; the acrylic coating helps prevent bore corrosion. The nitrile rubber lips and carbon-steel spring seat against the shaft surface, so any nicks or roughness will cause leaks. Do not exceed the 10 psi pressure limit or the 3 600 RPM speed rating, as excess pressure or speed leads to premature lip wear.

Critical specification for fit

The decisive figure is the 1.25 in inside diameter matched to a 2.374 in outside diameter with a .313 in width; if the shaft or housing dimensions differ, this seal will not seal correctly. Buyers who need a different bore size, a higher pressure rating or a single-lip design must select another part number.

Questions about this item

How can I confirm the SKF 12614 shaft seal is sealing correctly after installation?

After fitting, run the shaft up to 3,600 RPM and check for leaks; the nitrile rubber lips are rated for 10 psi maximum pressure and 6 mps surface speed.

What comes with the SKF 12614 shaft seal and what must I source separately?

The box contains the single CRWA1-design seal with acrylic-coated case, carbon-steel spring and dual nitrile lips; no installation tools or lubricant are included.

Which SKF 12614 variant should I choose for my application?

This part number covers one size only — 1.25 in inside diameter, 2.374 in outside diameter and .313 in width — so select it when those dimensions match your housing and shaft.
