UCFL200 Series 2-Bolt Flange Bearing Units — Standard Duty, Setscrew Locking
The UCFL200 series is the two-bolt oval flange equivalent of the UCF200 square four-bolt flange. Where the UCF200 uses a square plate with four corner bolts, the UCFL200 uses an oval housing with two bolts on the long axis — a format that requires less frame material, costs less to install, and suits locations where a square flange housing would overhang the mounting structure. The oval two-bolt format is the most widely used flange bearing configuration in light to medium duty industrial machinery: it mounts on a vertical face, minimises machine frame modifications, and uses the same UC insert and setscrew procedure as the UCP200 pillow block and UCF200 square flange, providing full interchangeability of insert bearings across all three formats for the same bore size.
Two-Bolt Oval Flange — When Less Is More
The four-bolt square flange provides higher housing rotation resistance under eccentric radial loads. The two-bolt oval flange costs less to install, requires fewer fixings, and allows the housing to be fitted in locations where only two bolt positions are available. For most light to medium duty applications — fan shafts, light conveyor drives, agricultural implement shafts, packaging machine drives — two M14 or M16 bolts in the J-dimension positions provide adequate retention, and the UCFL200 is the standard choice. Where field experience shows housing rotation on a UCFL200 installation, the upgrade path is the three-bolt UCFB200 bracket or the four-bolt UCF200 square flange, both of which accept the same insert bearing.
Key Features
