Exact Replacement Seal

The SKF 25074 rotary shaft seal fits a 2.5 in shaft and a 3.623 in bore with a .375 in width. It is designed for equipment that uses animal and vegetable oils, diesel, gasoline, greases, hot water, light heating oil or mineral oils.

Press-Fit Installation

The metal case with acrylic coating presses into the housing bore without special tools. A dry or damaged bore can cause leaks, so the bore surface must be clean and within tolerance before the seal is seated.

10 psi Pressure Limit

The single nitrile rubber lip with carbon steel spring is rated for a maximum of 10 psi. Systems that operate above this pressure will need a different sealing arrangement.

Questions about this item

How can I confirm the 2.5 in shaft seal is seated correctly after installation?

After fitting the 2.5 in inside-diameter seal, rotate the shaft by hand at low speed and check the contact lip for even seating and zero leakage at the 10 psi maximum pressure rating.

What comes in the box with the SKF 25074 and what must I source separately?

The box contains the single CRW1-design rotary shaft seal with NBR lip, carbon-steel spring and acrylic-coated case; installation tools, lubricant and any housing or shaft-sleeve components are not included.

Which size should I choose when the listing shows 2.5 x 3.623 x .375 in dimensions?

Select the 25074 part when your application requires exactly a 2.5 in inside diameter, 3.623 in outside diameter and .375 in overall width to match the shaft and housing bores.
