Product Identity

The Dayton 3FDD5 is a pillow block bearing with a 5/8 inch cylindrical bore designed for light-to-medium radial loads. It suits maintenance engineers, equipment assemblers and hobbyists who need a ready-to-mount housed bearing for conveyor rollers, fan shafts or agricultural machinery.

Critical Specification

The bore diameter of 5/8 inch is the single dimension that determines fit; the shaft must match this size exactly. The housing is cast iron with a 1 3/16 inch center height and a 3 3/4 inch bolt-hole spacing, while the insert uses 52100 chrome steel with double seals and NLGI #2 equivalent grease rated from -20 to 200 degrees F.

Installation Notes

Two bolt-through holes allow straightforward mounting on a flat surface using standard hardware. Ensure the mounting surface is level and the bolts are torqued evenly to prevent housing distortion. The double-sealed insert arrives pre-lubricated, so do not add grease before the first run-in period.

Questions about this item

How does the 5/8 inch bore translate to shaft fit in a real machine?

The 5/8 inch cylindrical bore matches a 5/8 inch shaft for a standard slip fit, secured by the bearing's set screws or locking collar.

What does the bolt-through mount type with two holes cap in practice?

The bolt-through mount uses two holes on a 3 3/4 inch centre-to-centre pattern, limiting attachment to surfaces that match that spacing.

What clearance does the 2.484 inch overall height and 1.5 inch width need to fit?

The housing stands 2.484 inches tall and 1.5 inches wide, so the mounting surface must provide at least that much vertical and lateral space.
