●   UKFC piloted round flanged units are suggested for industrial applications where normal loads are encountered.
●   UKFC piloted round flanged units ensure accurate mounting fits and provide better support for heavy loads.
●   Each unit comes assembled and ready for mounting, using bolts through the flange.
●   These units use wide inner ring ball bearings with self-aligning spherical outside diameters that compensate for shaft misalignment.
●   Timken UKFC series Mounted Bearings feature the Timken adapter sleeve locking (UK) bearing insert.
●   Bearing prelubricated and ready for immediate installation.
●   Grease fitting supplied for relubrication.
●   The bonded seal design is well-suited for industrial applications involving wet or dirty environments.
●   Bolt-hole spacing dimensions and shaft center location are interchangeable with competitive units.
●   Housing designed for ease of bearing replacement.
