This NTN UCF series light-duty flange ball bearing unit has a cast iron housing with four bolt holes, contact and flinger seals, and setscrew lock. It is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The one-piece housing is made of gray cast iron for rigidity and vibration damping, and has a solid base for mounting stability. The double-sealed, deep-groove radial ball bearing insert in the housing is made of through-hardened chromium steel and is rated "light duty" for applications with moderate radial loads and light thrust or combination loads. It has a wide, extended inner ring on both sides for increased shaft support and reduced inner-ring tilt for smooth operation. This self-aligning bearing has a convex sphered outer surface that compensates for misalignments. Steel-reinforced molded rubber lip seals on both sides of the bearing retain lubricant applied at manufacture and help keep contaminants out. For added protection, flingers on the inner ring deflect contaminants away from the seals. The bearing locks onto the shaft with two ball-point setscrews spaced 120 degrees apart for a three-point contact hold. The semi-retractable ball makes point
