A complete housed ball bearing unit in the three-bolt bracket flange style. The cast iron housing carries all three mounting bolts on one face, so the unit fastens from a single direction against a plate or frame upright. Bore is 35 mm (1-3/8 in). Locking is by two setscrews in the extended inner ring.
UC — wide inner ring insert bearing, setscrew locking, spherical outer surface for self-alignment
FK — three-bolt bracket flange housing, cast iron, mounting bolts on a single face
207 — 35 mm bore size code
Insert bearing number UC207, AISI 52100 bearing steel; housing number FK207
Three bolts, M8, bolt-to-bolt distance 55 mm. Overall bracket length 144 mm; bracket width 90 mm; height across the flange 70 mm. Total unit width 44.4 mm, of which the insert bearing accounts for 42.9 mm.
The three-bolt bracket concentrates its fasteners on one side of the bore, which is what allows installation where only one face of the mounting plate is reachable — a closed frame member, a tank wall, the inboard side of a conveyor stringer. That asymmetry means the third bolt carries the moment reaction, so the pattern favours moderate radial load with light overhung load. The spherical outer race of the insert takes up initial mounting misalignment at installation. Contact seals with a flinger on the outboard face exclude splash and airborne debris.

1 Pc. Complete housed unit: cast iron three-bolt bracket housing with the UC207 insert bearing and setscrews fitted, relubricatable through the 1/8-27 NPT fitting. Contact seals with flinger.
The bracket seats against a flat rigid face, shimmed where uneven, on three M8 fasteners at 55 mm bolt-to-bolt. The mounting bolts are drawn down first so the spherical insert settles into its aligned seat, then the setscrews are tightened against the shaft. Shaft seat is a commercial ground 35 mm diameter.
Same-style three-bolt bracket flange units to the JIS 200 series in 35 mm bore, sharing the 44.4 mm total width and 42.9 mm insert width: Asahi UCFK 207, Koyo UCFK207, FYH UCFK207, SKF UCFB 207/H. AMI’s UCFB207 line is also a three-bolt bracket but uses a different housing casting, so it is a related size rather than an interchange. The four-bolt AMI UCF207 and two-bolt AMI UCFL207 share the UC207 insert with a different housing and bolt pattern, so they are related sizes.
