How to read the UCT213 designation
| Segment | Meaning |
|---|---|
| UC | Insert bearing with set-screw locking and spherical outside diameter |
| T | Take-up housing (slides in a frame to tension a belt or chain) |
| 2 | 200 series (light duty) |
| 13 | Bore code 13 → 65 mm bore. ISO bore code (00–03 = 10/12/15/17 mm; 04 and above = code × 5 mm). |
UCT213 interchange
UCT213 is a housed unit: a UC213 insert bearing in a T213 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 names are trademarks of their respective owners. FULI is not affiliated with, authorized by or endorsed by these companies. Part numbers are shown for interchange reference only. FULI dimensions, load ratings and speeds come from the FULI catalog.
UCT213 compared with nearby sizes and housings
UCT213 is a take-up unit that holds the UC213 insert on a 65 mm shaft: dimension H 167 mm, dimension L 224 mm, dimension L1 137 mm and dimension N2 70 mm.
The same 213 size is also made as UCF213 (square flange unit, d 65 · L 187 · J 149 mm). All of them take the same UC213 insert, so a worn insert can be changed without changing the housing type.
UCT214 is the next larger size in the same series on this site: shaft d 70 mm (5 mm more), inner ring width B 74.6 mm (9.5 mm more), dimension H 167 mm (the same) and dimension L 224 mm (the same).
UCT210 is the next smaller size in the same series on this site: shaft d 50 mm (15 mm less), inner ring width B 51.6 mm (13.5 mm less), dimension H 117 mm (50 mm less) and dimension L 149 mm (75 mm less).

UCT213 load ratings
FULI's catalog has no load rating line for UCT213 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.
UCT213 dimensions in inches
The nearest common inch shaft size to the 65 mm bore of UCT213 is 2-9/16 in (65.09 mm), 0.09 mm larger than the bore, so UCT213 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 |
| Dimension H | 167 mm | 6.5748 in |
| Dimension L | 224 mm | 8.8189 in |
| Dimension L1 | 137 mm | 5.3937 in |
| Dimension N2 | 70 mm | 2.7559 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 UCT213 (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 UCT213 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 housing of UCT213 slides in the guides of the frame. Set the belt or chain tension with the adjusting screw first, then lock the insert to the shaft.
Grease for UCT213
The insert in UCT213 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 UCT213
FULI supplies UCT213 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 UCT213.

FAQ
What shaft size does UCT213 fit?
A 65 mm shaft (2.5591 in).
What is the difference between UCT213 and UCT214?
UCT214 is the next size up, for a 70 mm shaft, with inner ring width B 74.6 mm (9.5 mm more), dimension H 167 mm (the same) and dimension L 224 mm (the same). Choose UCT214 when the shaft is larger or the load is higher; the housings are not interchangeable.
Which insert fits UCT213?
The UC213 insert (65 × 120 × 65.1 mm). It is sold on its own for replacement.
UCT213 or UCF213: which should I use?
Both hold the same UC213 insert on a 65 mm shaft. UCT213 is a take-up unit (d 65 · H 167 · L 224 mm); UCF213 is a square flange unit (d 65 · L 187 · J 149 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 UCT213 come as a complete unit or insert only?
UCT213 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 UCT213?
Load ratings for UCT213 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.
