UCP202 interchange
UCP202 is a housed unit: a UC202 insert bearing in a P202 housing. The insert bearing dimensions follow ISO and interchange between manufacturers. Housing dimensions such as bolt hole spacing can differ between the JIS and ISO versions of the same designation, so please confirm the mounting dimensions with us before ordering.

UCP202 compared with nearby sizes and housings
UCP202 is a pillow block unit that holds the UC202 insert on a 15 mm shaft: centre height H 30.2 mm, base length L 127 mm and overall height H0 62 mm with M10 bolts.
UCP204 is the next larger size in the same series on this site: shaft d 20 mm (5 mm more), inner ring width B 31 mm (the same), centre height H 33.3 mm (3.1 mm more) and bolt spacing J 95 mm (the same).

UCP202 load ratings
FULI's catalog has no load rating line for UCP202 itself, so none is given here. The ratings of the UC202 insert are on its own page. Ask us and we send the figures with the quotation.
UCP202 dimensions in inches
The nearest common inch shaft size to the 15 mm bore of UCP202 is 9/16 in (14.29 mm), 0.71 mm smaller than the bore, so UCP202 would be loose on it. An inch shaft needs an inch bore insert. Inch bore versions are made for some sizes; ask us with the shaft size.
| Dimension | Millimetres | Inches |
|---|---|---|
| Shaft diameter d | 15 mm | 0.5906 in |
| Centre height H | 30.2 mm | 1.1890 in |
| Base length L | 127 mm | 5.0000 in |
| Bolt hole spacing J | 95 mm | 3.7402 in |
| Overall height H0 | 62 mm | 2.4409 in |
| Insert width B | 31 mm | 1.2205 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Mounting UCP202 (general guidance)
General guidance, not a FULI specification: insert bearings slide onto the shaft rather than being pressed on, and are held by their locking device. A shaft ground or drawn to h7 is common; a closer shaft such as js7 or j7 suits higher speed.
The UC202 insert in UCP202 is locked by set screws in the extended inner ring. Housed-unit problems usually start at the set screws: if the inner ring is not held, it turns on the shaft and wears it. Tighten each screw to the torque in the mounting instructions, and check them again after the first hours of running.
Bolt UCP202 down with M10 bolts at 95 mm spacing on a flat, rigid face. Line up the two housings on a shaft before tightening the bolts fully, then lock the inserts, so the shaft is not bent between them.
Grease for UCP202
The insert in UCP202 is sealed on both sides and greased at the factory. If the housing has a grease fitting, add grease slowly through it while the shaft turns until a little fresh grease shows at the seals; general practice is to relubricate more often in wet or dusty places.
Greases for a stated temperature range can be specified on the order; for North America a range of −40 to 120 °C is often asked for.
How FULI supplies UCP202
FULI supplies UCP202 as a complete unit, or the UC202 insert on its own for replacement. Before packing, the factory checks the mounting torque, the fit of the insert in the housing, the radial clearance and that the base-to-centre height is consistent across the batch.
Rings are marked with a brand you are authorised to use, with the FULI brand, or left neutral, as your order states. The box is printed with the model, precision class and brand.
Inquiries that leave out the prefix or suffix letters are the usual cause of a wrong quote, so write the full designation, for example UCP202.

FAQ
What shaft size does UCP202 fit?
A 15 mm shaft (0.5906 in).
What is the difference between UCP202 and UCP204?
UCP204 is the next size up, for a 20 mm shaft, with inner ring width B 31 mm (the same), centre height H 33.3 mm (3.1 mm more) and bolt spacing J 95 mm (the same). Choose UCP204 when the shaft is larger or the load is higher; the housings are not interchangeable.
Which insert fits UCP202?
The UC202 insert (15 × 47 × 31 mm). It is sold on its own for replacement.
Does UCP202 come as a complete unit or insert only?
UCP202 is normally supplied as a complete unit (insert bearing already fitted in the housing). The insert can also be quoted separately if you are replacing only the bearing.
Where are the load ratings for UCP202?
Load ratings for UCP202 are being checked against FULI's catalog and are not shown on this page yet. Model pages with a "Load ratings & speed" table carry values from FULI's catalog.
