How to read the UCF212 designation
| Segment | Meaning |
|---|---|
| UC | Insert bearing with set-screw locking and spherical outside diameter |
| F | Four-bolt square flange housing |
| 2 | 200 series (light duty) |

UCF212 interchange by brand
UCF212 is a housed unit: a UC212 insert bearing in an F212 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.
| Brand | Designation |
|---|---|
| SKF | UCF 212 |
| Timken | UCF212 |
| Koyo | UCF212 |
Same designation; confirm housing bolt spacing.

UCF212 compared with nearby sizes and housings
UCF212 is a square flange unit that holds the UC212 insert on a 60 mm shaft: flange length L 175 mm with M16 bolts.
The same 212 size is also made as UCP212 (pillow block unit, d 60 · H 69.8 · J 184 mm). All of them take the same UC212 insert, so a worn insert can be changed without changing the housing type.
UCF213 is the next larger size in the same series on this site: shaft d 65 mm (5 mm more), inner ring width B 65.1 mm (the same), length L 187 mm (12 mm more) and bolt spacing J 149 mm (6 mm more).
UCF211 is the next smaller size in the same series on this site: shaft d 55 mm (5 mm less), inner ring width B 55.6 mm (9.5 mm less), length L 162 mm (13 mm less) and bolt spacing J 130 mm (13 mm less).

UCF212 load ratings
FULI's catalog has no load rating line for UCF212 itself, so none is given here. The ratings of the UC212 insert are on its own page. Ask us and we send the figures with the quotation.
UCF212 dimensions in inches
The nearest common inch shaft size to the 60 mm bore of UCF212 is 2-3/8 in (60.33 mm), 0.33 mm larger than the bore, so UCF212 will not go 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 | 60 mm | 2.3622 in |
| Flange length L | 175 mm | 6.8898 in |
| Bolt hole spacing J | 143 mm | 5.6299 in |
| Insert width B | 65.1 mm | 2.5630 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Mounting UCF212 (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 UC212 insert in UCF212 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 UCF212 down with M16 bolts at 143 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 UCF212
The insert in UCF212 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 UCF212
FULI supplies UCF212 as a complete unit, or the UC212 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 UCF212.

FAQ
What shaft size does UCF212 fit?
A 60 mm shaft (2.3622 in).
What is the difference between UCF212 and UCF213?
UCF213 is the next size up, for a 65 mm shaft, with inner ring width B 65.1 mm (the same), length L 187 mm (12 mm more) and bolt spacing J 149 mm (6 mm more). Choose UCF213 when the shaft is larger or the load is higher; the housings are not interchangeable.
Which insert fits UCF212?
The UC212 insert (60 × 110 × 65.1 mm). It is sold on its own for replacement.
UCF212 or UCP212: which should I use?
Both hold the same UC212 insert on a 60 mm shaft. UCF212 is a square flange unit (d 60 · L 175 · J 143 mm); UCP212 is a pillow block unit (d 60 · H 69.8 · J 184 mm). Choose by how the bearing is fixed to the machine: a pillow block bolts to a surface parallel to the shaft, a flange to a face across it.
Does UCF212 come as a complete unit or insert only?
UCF212 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 UCF212?
Load ratings for UCF212 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.
