UCFCSX00 Series Medium Duty Inch-Based Flange Cartridge Units
UCFCSX00 combines two selection factors that are easy to miss in a quick visual comparison: medium-duty construction and inch-oriented cartridge geometry. The catalogue lists base sizes from 25 mm through 100 mm with inch bore variants identified by suffix, and published unit weights reach 18.50 kg.
For a replacement buyer, the safest method is to preserve the complete part marking and then verify the drawing. A standard-duty UCFCS or a metric UCFCX can be close enough in appearance to cause confusion, but the series, suffix and housing dimensions together identify the correct package.
For a wider housing comparison, browse the bearings range before finalising the mounting style.
Where the heavier S-X cartridge is used
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.
Heavy conveyor stations on inch shafting
A useful fit where an imperial or mixed-standard shaft system meets a robust face-mounted bearing requirement.
Large imported machinery
The series helps maintain original housing geometry on equipment that was not designed around a standard metric UCFC layout.
OEM machines sold into inch markets
Designers can retain a medium-duty cartridge platform while specifying inch bore variants for regional shaft standards.
Maintenance of long-life capital equipment
Keeping the original S-X family can avoid frame rework during bearing replacement.
UCFCSX00 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.

| Published metric / inch options | 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 85, 100 mm base sizes; inch variants listed by suffix |
| Housing / mounting style | 4-bolt piloted flange cartridge, inch-based housing geometry |
| Housing construction | Cast iron |
| Catalog dimensional fields | D2, P, J, A2, N, L, H1, A1, D1, S, B, Z and weight |
| Published unit weight | 1.34-18.50 kg |
Two requirements in one series: medium duty and inch geometry
Medium-duty X-series
The catalogue classifies UCFCSX00 as the heavier duty counterpart to UCFCS200.
Inch variants by suffix
Full model identification is essential because the base series alone does not describe every bore option.
25-100 mm base-size span
The published range extends farther than the standard-duty UCFCS family.
Up to 18.50 kg published weight
Larger units require more attention to handling, surrounding clearance and the strength of the mounting structure.
Handling and mounting the larger sizes
Warehouse labels and purchase orders should carry the complete model.
Large cast cartridges should not be allowed to hang on the shaft when the final mounting bolt is released.
Medium-duty housings need full seating; warped platework can create alignment problems.
Large units are worth including in the initial run-in inspection schedule for the rebuilt machine.
A four-point identity check for UCFCSX00
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.
Confirm that the machine actually calls for the X-series body before comparing shaft size.
Photograph or record suffixes before disposal; they can distinguish an inch-bore version.
Compare pilot, bolt circle and overall flange dimensions with the catalogue drawing.
Allow for unit mass, lifting access and safe support during service on the upper end of the range.
Avoiding cross-family substitutions
UCFCSX00 is the medium-duty, inch-oriented cartridge family. Use UCFCS200 when the same geometry is required at standard duty, or UCFCX00 when the application is based on the regular metric FC layout. A common bore diameter does not make these housings automatically interchangeable.
Send the machine details for a model check
For UCFCSX00, send the existing model marking, shaft diameter, mounting dimensions and a photo of the bearing position. GBC can review the information against the published series before quotation. Email: sales@australia-drive.com.
