SKF 27268 Rotary Shaft Seal

This SKF 27268 rotary shaft seal fits shafts with a 2.75 in inside diameter and a 3.5 in outside diameter. The CRW1 design uses a single nitrile rubber lip held by a carbon steel spring. It is built for standard engine sealing tasks.

Nitrile lip handles oils and fuels

The nitrile rubber lip resists mineral oils, diesel, gasoline, greases, animal and vegetable oils, light heating oil and hot water. An acrylic case coating protects the metal shell. The single-lip CRW1 construction keeps the seal simple to install.

10 psi pressure limit decides fit

Maximum operating pressure is 10 psi with a top rotational speed of 520 RPM and surface speed of 9.19 mps. Exceeding these values will cause premature leakage. Verify your application stays within these limits before fitting.

Questions about this item

How often will the nitrile lip need replacement at 2 520 RPM?

Lip life depends on shaft finish, lubrication cleanliness and operating temperature; inspect at each scheduled service and replace if wear or hardening appears.

What limit appears first during continuous running at 2 520 RPM?

The 10 psi pressure ceiling and 9.19 mps surface speed are the published maximums; exceeding either accelerates lip wear and leakage.

How much heat does the seal generate when running all day at 2 520 RPM?

Frictional heat rises with shaft speed and load; ensure adequate oil splash or circulation so the nitrile stays within its temperature range.
