SKF F4B203-TF flanged ball bearing unit (ucf / ucfc / ucfl). Square four-bolt (UCF), round three-bolt (UCFC) or oval two-bolt (UCFL) flanged housing pre-assembled with a spherical-outer-ring insert bearing. Absorbs shaft-to-housing misalignment on assembly. Set-screw shaft attachment on standard UC-series insert; eccentric-collar (UEL) or adapter-sleeve (UK) variants available. Dimensioned to ISO 3228 / DIN 626.
