Product identity

The SKF 17284 is a rotary shaft seal designed for equipment that requires a 1.75 in inside diameter and a 2.437 in outside diameter. It suits maintenance teams and original-equipment assemblers who need a single-lip NBR seal for common industrial fluids.

Build and fit

The CRW1 design uses a carbon-steel spring to maintain lip contact at pressures up to 10 psi and speeds up to 3, 180 RPM. An acrylic case coating eases installation in standard inch-dimension housings without special tooling.

Included items

The package supplies the seal only; no installation sleeve, lubricant or additional hardware is bundled. Users should verify shaft finish and housing bore tolerances before fitting to ensure the 0.313 in width seats correctly.
