UCFCS200 Series Inch-Based Flange Cartridge Bearing Units
UCFCS200 is useful when the machine is built around an inch-oriented cartridge layout rather than the purely metric geometry usually associated with UCFC200. The catalogue shows metric base sizes from 30 to 75 mm together with inch bore variants identified by suffix, so the full model code matters during ordering.
This series is especially relevant on imported, legacy or mixed-standard machinery. A technician may measure a shaft in inches while the housing looks like a familiar four-bolt FC unit. UCFCS200 gives a route to preserve that original geometry without forcing a metric substitution.
For a wider housing comparison, browse the bearings range before finalising the mounting style.
A cartridge series for mixed metric and inch environments
Inch-based housing geometry
The catalogue identifies this family separately from the standard metric cartridge range.
Inch bore variants by suffix
The suffix can carry critical bore information, so shortening the model code can create an ordering error.
Standard-duty construction
UCFCS200 is the standard-duty version of this inch-oriented cartridge concept.
Setscrew locking
The insert uses a direct setscrew retention method familiar to many maintenance teams.
UCFCS200 published technical range
The table below keeps the catalogue values used for this series. Use the model-specific drawing for the final interchange decision; dimensions and suffixes can vary inside a family.

Decode the suffix before comparing dimensions
Use the product drawing as the final dimensional authority. The points below are practical filters that help narrow the correct model before a full drawing comparison.
Do not order from “UCFCS206” style base numbers alone when the existing unit carries an inch-bore suffix.
Keep inch measurements as inches during the first comparison instead of rounding early to a nearby metric size.
Pilot, bolt pattern and flange thickness can identify an S-series housing even when another family offers the same nominal shaft size.
Compare the insert width and shaft projection because inch variants can be installed in machines with tight spacer or pulley positions.
Best-fit scenarios for UCFCS200
These are application patterns where the housing concept is commonly considered. Final suitability still depends on load, speed, alignment, environment and the machine designer’s requirements.
Imported production equipment
Suitable for machines whose bearing stations were designed around imperial shafting or inch-based replacement conventions.
Legacy conveyors and packaging lines
Helps preserve original mounting geometry when rebuilding older equipment with mixed metric and inch components.
Service stock for export machinery
OEMs supporting machines in inch-dominant markets can keep the correct cartridge family rather than supplying an approximate metric substitute.
Retrofit projects with dimensional constraints
Useful when the old housing footprint must remain unchanged while the bearing station is renewed.
Replacement work on legacy inch-based machines
Store the measured shaft diameter, model suffix and drawing reference together.
A mismatched housing should not be made to fit by altering the machine until the correct series has been ruled out.
Setscrew marks, corrosion and wear should be corrected before the new insert is locked.
This prevents a later store-room substitution with a visually similar UCFC unit.
How UCFCS200 differs from nearby cartridge families
UCFCS200 is the standard-duty inch-oriented cartridge family. UCFCSX00 serves the same general market with medium-duty construction. UCFC200 and UCFCX00 are the natural comparisons when the machine is based on the regular metric FC geometry.
