SKF 27362 Rotary Shaft Seal

The SKF 27362 is a CRWA1 rotary shaft seal designed for fluid retention in rotating equipment. It features a 2.75 in inside diameter, 3.751 in outside diameter and .438 in overall width. The nitrile rubber lip material handles animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil and mineral oils.

Mechanics needing a 2.75 in ID seal for moderate

This seal suits applications running up to 2,520 RPM with a maximum surface speed of 9.19 mps and a pressure limit of 10 psi. It is not for buyers who need higher pressure capability, greater surface speed or a different inside diameter. The dual-lip carbon steel spring design addresses standard rotary sealing requirements.

2.75 in inside diameter confirms fit

The 2.75 in inside diameter is the critical dimension that determines whether this seal matches the shaft. Verify the shaft size, 3.751 in bore diameter and .438 in width against the housing before ordering. The acrylic-coated case and NBR lip material complete the specification for compatible fluids.
