UC212 interchange
UC212 is an ISO designation. The boundary dimensions are identical across manufacturers; only suffixes (seals, clearance, cage) differ.

UC212 compared with nearby sizes and housings
UC212 is a set-screw insert for a 60 mm shaft: outside diameter 110 mm, inner ring width 65.1 mm and outer ring width 27 mm.
The UC212 insert is the one fitted in UCP212 (pillow block unit) and UCF212 (square flange unit).
UC213 is the next larger size in the same series on this site: shaft d 65 mm (5 mm more), outside diameter D 120 mm (10 mm more) and inner ring width B 65.1 mm (the same).
UC211 is the next smaller size in the same series on this site: shaft d 55 mm (5 mm less), outside diameter D 100 mm (10 mm less) and inner ring width B 55.6 mm (9.5 mm less).

| UC211 | insert bearing | 55 × 100 × 55.6 mm (d × D × B) | 1.12 |
| UC213 | insert bearing | 65 × 120 × 65.1 mm (d × D × B) | 1.86 |

UC212 weight, load ratings and speed
FULI's catalog gives about 1.54 kg for the insert, so 100 pieces of UC212 weigh about 154 kg before packing.
The catalog lists UC212 with a dynamic load rating of 52.5 kN and a static load rating of 36.0 kN. Its speed limits depend on the shaft tolerance: 2,400 rpm on a js7 or j7 shaft and 1,800 rpm on an h7 shaft. A closer shaft fit holds the inner ring more evenly, which is why the js7 / j7 figure is higher.

UC212 dimensions in inches
The nearest common inch shaft size to the 60 mm bore of UC212 is 2-3/8 in (60.33 mm), 0.33 mm larger than the bore, so UC212 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 |
|---|---|---|
| Bore d | 60 mm | 2.3622 in |
| Outside diameter D | 110 mm | 4.3307 in |
| Inner ring width B | 65.1 mm | 2.5630 in |
| Outer ring width C | 27 mm | 1.0630 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Mounting UC212 (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. For UC212 the catalog gives 2,400 and 1,800 rpm for the two cases.
UC212 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.
The spherical outside diameter of UC212 lets the insert swivel in the housing seat while it is being mounted, which takes up small errors in shaft line. It does not make the bearing a self-aligning bearing in service.
Grease for UC212
The insert is sealed on both sides and greased at the factory. Fitted in a housing with a grease fitting, it can be relubricated through the housing; on its own it runs on the factory fill.
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 UC212
FULI supplies UC212 on its own as a replacement insert, or fitted in a housing as a complete unit. The rings and balls are GCr15 chrome steel and the radial clearance is C0 as standard, with C3 on request.
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 UC212.

FAQ
What shaft size does UC212 fit?
A 60 mm shaft (2.3622 in).
What is the difference between UC212 and UC213?
UC213 is the next size up, for a 65 mm shaft, with outside diameter D 120 mm (10 mm more) and inner ring width B 65.1 mm (the same). Choose UC213 when the shaft is larger or the load is higher; the housings are not interchangeable.
Which housings fit the UC212 insert?
UCP212 (pillow block unit) and UCF212 (square flange unit) all use UC212. Order UC212 on its own to replace a worn insert in any of them.
How much does UC212 weigh?
About 1.54 kg in FULI's catalog; 100 pieces weigh about 154 kg before packing.
Can UC212 be ordered as an insert only, or as a complete unit?
Both. UC212 can be supplied on its own as a replacement insert for an existing housing, or fitted in a housing such as the UCP212 pillow block or UCF212 square flange and supplied as a complete unit. Tell us which you need when you send the inquiry.
