1 in Cast Iron Pillow Block Bearing

The Dayton 3FCP4 is a new cast iron pillow block bearing with a 1 in cylindrical bore and double-sealed radial ball insert. It suits maintenance teams and OEM builders who need a bolt-through mounted unit for moderate-speed shafts in conveyors, fans or agricultural equipment. The set screw locking collar secures the inner ring without adapter sleeves.

Upgrade from unsealed or pressed-steel units

Replacing open bearings or light-gauge housings with this cast iron, double-sealed design cuts contaminant ingress and extends relubrication intervals when the application runs between -20 Degrees F and 200 Degrees F. The jump is worth it when downtime for bearing changes costs more than the heavier housing and the NGLI #2 equivalent grease already packed at the factory.

Bolt-through mounting limits

Two bolt holes on 4 1/8 in centres fix the housing to a flat base; the 1.5 in overall width and 2.75 in overall height set the envelope for guard clearance. Shaft alignment must stay within the self-aligning capacity of the radial ball insert because the housing cannot be shimmed or adjusted after the bolts are torqued.

Questions about this item

What bolt spacing does the 1 in pillow block need?

The housing has two bolt-through holes on 4 1/8 in centres, so drill or use existing holes at that pitch.

Which way do the set screws go in and how tight?

Slip the bearing onto the shaft, seat the housing, then tighten both set screws on the inner ring alternately until each reaches the maker's torque value.

When should the radial ball insert be replaced?

Replace the insert when seal lips are torn, grease is contaminated, or the bearing runs rough or hot beyond the -20 to 200 °F range.
