NTN 4 Bolt Flange Bearing: Radial Ball, 1 7/16 in Bore, Cast Iron, Set Screws

The NTN 4 Bolt Flange Bearing is used to support rotating shafts in industrial machinery, conveyors, and material handling equipment. Its cast iron housing with set screw locking secures the shaft, while the radial ball design handles moderate radial and axial loads. It is suitable for general purpose applications requiring a compact, square flange mount.

The NTN UCFU-1.7/16MFG1 has a 1 7/16 in cylindrical bore, cast iron housing with set screw locking, and a square 4-bolt flange. It uses NLGI #3 equivalent lubricant, requires a 1/2 in mounting bolt, and measures 4 21/32 in length. This inch-system bearing is designed for general purpose flange-mount applications.

To install an NTN 4 bolt flange bearing, first ensure the shaft is clean and free of burrs. Slide the bearing onto the shaft, align the flange bolt holes with the mounting surface, and tighten the 1/2 in bolts evenly. Then tighten the set screws against the shaft using a hex key. Apply moderate torque to avoid distorting the housing.
