UCFT200 Series 2-Bolt Flange Bearing Units — Inch-Based Housing, Setscrew Locking
The UCFT200 series provides a standard duty cast iron two-bolt oval flange bearing unit with setscrew locking in an inch-based housing format. All H, J, A2, A1, A, and L dimensions correspond to inch-fraction equivalents rather than the rounded metric values of the UCFL200, making the UCFT200 the direct bolt-in replacement for inch-standard oval flange setscrew bearings in North American (ANSI), British (BS), and Australian Standards machinery where re-drilling the mounting panel to metric spacing is not practical.
The UC series wide inner ring insert bearing and dual 120° setscrew locking are identical in function to the metric UCFL200 equivalent, providing the same self-aligning spherical OD, axial float capacity, and bidirectional retention. The difference is entirely in the housing dimensions: a UCFT204 (20 mm bore) has J = 89.7 mm versus UCFL204 J = 90 mm. That 0.3 mm difference is significant when existing machine frame holes are drilled to the inch-fraction position and a metric housing would require slot-drilling to fit.
Inch Housing vs Metric Housing — When It Matters
Inch-standard oval flange bearings (FT series) originate from North American and British engineering practice where bolt-hole positions, housing heights, and overall lengths are all derived from inch fractions. When an OEM specifies a replacement bearing by a North American part number, or when a legacy machine carries drilled holes at inch-standard spacing, specifying UCFT200 eliminates the need for slot drilling, oversized holes, or spacer plates to adapt a metric UCFL200 to the existing hole pattern. For new machines designed in metric, UCFL200 is the standard choice — UCFT200 addresses the retrofit and replacement market.
