Dayton

Dayton 3FCW2 2-Bolt Flange Bearing 1-3/4" Bore

SKU CH-97Q4-8VKNP

Two-bolt flange bearing with 1-3/4" bore, cast-iron housing and single-sealed ball insert rated to 3,800 RPM

  • 1-3/4" bore fits standard shafts
  • Cast-iron housing handles heavy radial loads
  • 52100 chrome-steel balls resist wear
  • Single seal keeps dust and dirt out
  • 3,800 RPM grease rating suits high-speed runs

What This Bearing Is

The Dayton 3FCW2 is a new 2-bolt flange bearing with a 1-3/4" cylindrical bore. It uses a WJB UC209-28 insert made from 52100 chrome steel and runs in a cast-iron rhombus housing. The unit is single sealed and pre-lubricated with Chevron SRI 2 grease rated to NLGI #2 equivalent for highly dusty and dirty environments.

Who Should Use It

This bearing suits maintenance crews replacing a fixed radial ball unit on a 1-3/4" shaft where a 2-bolt rhombus flange pattern is specified. It is not for buyers who need an expansion-type bearing, a different bore size, a four-bolt mounting pattern, or a housing material other than cast iron.

Build Integration

The flange mounts with two bolts on a 0.858" back-side-to-centre width and a 2 3/16" centre height. The fixed expansion type locks the shaft axially, while the single seal and factory grease remove the need for initial lubrication. Maximum rated speed is 3,800 RPM with grease lubrication.

Highlights

  • Cast-iron housing handles heavy radial loads
  • 52100 chrome-steel balls resist wear
