SKU CH-KSPY-KWZD4

Four-bolt square flange bearing with a 2-7/16" cylindrical bore, alloy-steel radial ball insert and cast-iron housing for highly dusty environments

  • 4-bolt square flange simplifies mounting
  • 2-7/16" cylindrical bore fits matching shafts
  • Single-sealed radial ball insert resists dust and dirt
  • Cast-iron housing withstands harsh environments
  • 3000 RPM grease-lubricated speed rating for reliable operation

Bore Size and Mounting Pattern

The Dayton 3FCY7 is a four-bolt flange bearing with a 2-7/16 inch cylindrical bore. It uses a WJB UC212-39 insert bearing made from alloy steel and a single-sealed closure. The cast-iron square housing suits fixed-expansion installations in highly dusty and dirty environments.

Speed Limit and Lubrication

The bearing carries a maximum speed rating of 3,000 RPM when lubricated with the supplied Chevron SRI 2 grease, an NLGI #2 equivalent. The back-side-to-centre width measures 1.142 inches, and the centre height is 3 7/16 inches. Operation beyond the rated speed or with incompatible lubricants will reduce service life.

Chemical Exposure Warning

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm under Proposition 65. Buyers who require a bearing certified free of listed substances must select a different part. No other regulatory restrictions apply.

Questions about this item

How do I confirm the 2-7/16" bore matches my shaft?

Measure the shaft diameter directly; the bearing accepts a cylindrical bore of exactly 2-7/16 inches, so the shaft must be that size for a proper fit.

What does the 3,000 RPM grease rating mean for daily operation?

The bearing is rated for a maximum speed of 3,000 RPM with the supplied Chevron SRI 2 grease; running faster risks overheating and premature wear.

How does the 4-bolt square flange affect mounting?

The square, 4-bolt flange provides a rigid, fixed housing that bolts flat against a mounting surface, keeping the 3-7/16" center height aligned.
