SKF 32395 Rotary Shaft Seal

The SKF 32395 is a rotary shaft seal designed for automotive engine applications. It fits shafts with a 3.25 in inside diameter and a 4.249 in outside diameter. The seal uses a CRWA1 design with two nitrile rubber lips and a carbon steel spring. It is suitable for mechanics and technicians repairing engines or gearboxes requiring this specific size.

Thermals Noise and Power Draw

As a passive sealing component, the SKF 32395 generates no noise and draws no power during operation. Its performance relates to containing fluids at a maximum pressure of 10 psi and a maximum surface speed of 9.87 mps. The nitrile rubber lip material handles operating temperatures for the listed compatible fluids. Frictional heat depends on the application speed and lubrication conditions present.

Bundled Accessories and Software

The product is supplied as a single replacement seal with no additional accessories, installation tools, or software included. The acrylic case coating helps protect the metal case during storage and installation. No supplemental items change the sealing capability or the installation procedure for the end user.

Questions about this item

How do I press the 3.25 in ID SKF 32395 seal into its 4.249 in bore without damaging the acrylic-coated case?

Use a flat drift that contacts only the outer steel shell and tap evenly around the circumference until the 0.375 in wide seal sits flush; avoid hammering on the nitrile lips or the spring.

When should I plan to replace this double-lip NBR shaft seal in a diesel or gasoline environment?

Inspect the 3.25 in contact surface at each oil change; replace the SKF 32395 if the nitrile lips harden, crack or leak, typically after the service interval recommended for the host equipment.

What rotational speed limit will I hit first if the shaft runs continuously at the 10 psi pressure rating?

The 2,280 RPM ceiling for the CRWA1 design is reached before the 9.87 m/s surface-speed limit under sustained operation.
