UCT210 interchange
UCT210 is a housed unit: a UC210 insert bearing in a T210 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.
UCT210 compared with nearby sizes and housings
UCT210 is a take-up unit that holds the UC210 insert on a 50 mm shaft: dimension H 117 mm, dimension L 149 mm, dimension L1 90 mm and dimension N2 49 mm.
The same 210 size is also made as UCP210 (pillow block unit, d 50 · H 57.2 · J 159 mm) and UCF210 (square flange unit, d 50 · L 143 · J 111 mm). All of them take the same UC210 insert, so a worn insert can be changed without changing the housing type.
UCT213 is the next larger size in the same series on this site: shaft d 65 mm (15 mm more), inner ring width B 65.1 mm (13.5 mm more), dimension H 167 mm (50 mm more) and dimension L 224 mm (75 mm more).
UCT206 is the next smaller size in the same series on this site: shaft d 30 mm (20 mm less), inner ring width B 38.1 mm (13.5 mm less), dimension H 102 mm (15 mm less) and dimension L 113 mm (36 mm less).
| Model | Type | Main dimensions | Weight (kg) |

| UCT206 | take-up unit | d 30 · H 102 · L 113 mm | 1.3 |
| UCT213 | take-up unit | d 65 · H 167 · L 224 mm | — |
| UC210 | insert bearing | 50 × 90 × 51.6 mm (d × D × B) | 0.80 |

UCT210 weight, load ratings and speed
FULI's catalog gives about 2.6 kg for the complete unit, housing and insert together, so 100 pieces of UCT210 weigh about 260 kg before packing.
The catalog lists UCT210 with a dynamic load rating of 35 kN and a static load rating of 23.2 kN. Its speed limits depend on the shaft tolerance: 3,000 rpm on a js7 or j7 shaft and 2,200 rpm on an h7 shaft. A closer shaft fit holds the inner ring more evenly, which is why the js7 / j7 figure is higher.

UCT210 dimensions in inches
The nearest common inch shaft size to the 50 mm bore of UCT210 is 1-15/16 in (49.21 mm), 0.79 mm smaller than the bore, so UCT210 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 | 50 mm | 1.9685 in |
| Dimension H | 117 mm | 4.6063 in |
| Dimension L | 149 mm | 5.8661 in |
| Dimension L1 | 90 mm | 3.5433 in |
| Dimension N2 | 49 mm | 1.9291 in |
| Insert width B | 51.6 mm | 2.0315 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Mounting UCT210 (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 UCT210 the catalog gives 3,000 and 2,200 rpm for the two cases.
The UC210 insert in UCT210 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 UCT210 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 UCT210
The insert in UCT210 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 UCT210
FULI supplies UCT210 as a complete unit, or the UC210 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 UCT210.

FAQ
What shaft size does UCT210 fit?
A 50 mm shaft (1.9685 in).
What is the difference between UCT210 and UCT213?
UCT213 is the next size up, for a 65 mm shaft, with inner ring width B 65.1 mm (13.5 mm more), dimension H 167 mm (50 mm more) and dimension L 224 mm (75 mm more). Choose UCT213 when the shaft is larger or the load is higher; the housings are not interchangeable.
Which insert fits UCT210?
The UC210 insert (50 × 90 × 51.6 mm). It is sold on its own for replacement.
UCT210 or UCP210: which should I use?
Both hold the same UC210 insert on a 50 mm shaft. UCT210 is a take-up unit (d 50 · H 117 · L 149 mm); UCP210 is a pillow block unit (d 50 · H 57.2 · J 159 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.
How much does UCT210 weigh?
About 2.6 kg in FULI's catalog; 100 pieces weigh about 260 kg before packing.
Does UCT210 come as a complete unit or insert only?
UCT210 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.
