UCF213 interchange
UCF213 is a housed unit: a UC213 insert bearing in an F213 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.

UCF213 compared with nearby sizes and housings
UCF213 is a square flange unit that holds the UC213 insert on a 65 mm shaft: flange length L 187 mm with M16 bolts.
UCF212 is the next smaller size in the same series on this site: shaft d 60 mm (5 mm less), inner ring width B 65.1 mm (the same), length L 175 mm (12 mm less) and bolt spacing J 143 mm (6 mm less).

UCF213 load ratings
FULI's catalog has no load rating line for UCF213 itself, so none is given here. The ratings of the UC213 insert are on its own page. Ask us and we send the figures with the quotation.
UCF213 dimensions in inches
The nearest common inch shaft size to the 65 mm bore of UCF213 is 2-9/16 in (65.09 mm), 0.09 mm larger than the bore, so UCF213 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 | 65 mm | 2.5591 in |
| Flange length L | 187 mm | 7.3622 in |
| Bolt hole spacing J | 149 mm | 5.8661 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 UCF213 (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 UC213 insert in UCF213 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 UCF213 down with M16 bolts at 149 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 UCF213
The insert in UCF213 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 UCF213
FULI supplies UCF213 as a complete unit, or the UC213 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 UCF213.
