SKF 13052 CRWA1 Shaft Seal

The SKF 13052 is a CRWA1 rotary shaft seal built for automotive engine maintenance. It fits a 1.313 in shaft and a 2.062 in bore with a 0.313 in overall width. Mechanics use it to retain lubricants and exclude contamination in rotating assemblies.

Replaces worn lip seals on shafts up to 1.313 in

Swap it in when the original seal leaks or hardens from heat and fluid exposure. The jump is worth it when a twin-lip nitrile design rated for 10 psi and 3,540 RPM restores sealing life on gasoline, diesel, oil, grease or hot water systems.

Fits standard inch-dimension housings

The carbon-steel spring maintains lip pressure while the acrylic-coated case resists bore corrosion. Two nitrile lips handle surface speeds to 6.2 mps, freeing the surrounding bearings and housings from fluid loss and abrasive ingress.

Questions about this item

What bore diameter and housing depth does the 1.313 in shaft seal need to fit?

The seal installs in a 2.062 in bore with an overall width of .313 in, so the housing must match those dimensions for the carbon-steel spring case to seat correctly.

How do you install the CRWA1 seal without damaging the nitrile lips?

Lubricate the shaft and seal lips with compatible oil, then press the seal squarely using a driver that contacts only the outer metal case until it bottoms at the .313 in width.

When should the 13052 seal be replaced under normal service?

Replace the seal if leakage appears, the nitrile lips harden or crack, or the shaft shows grooving; the carbon-steel spring and acrylic-coated case remain serviceable unless corroded.
