UCP210 interchange
UCP210 is a housed unit: a UC210 insert bearing in a P210 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.

UCP210 compared with nearby sizes and housings
UCP210 is a pillow block unit that holds the UC210 insert on a 50 mm shaft: centre height H 57.2 mm, base length L 206 mm and overall height H0 114 mm with M16 bolts.
The same 210 size is also made as 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.
UCP211 is the next larger size in the same series on this site: shaft d 55 mm (5 mm more), inner ring width B 55.6 mm (4 mm more), centre height H 63.5 mm (6.3 mm more), length L 219 mm (13 mm more), bolt spacing J 171 mm (12 mm more) and overall height H0 126 mm (12 mm more).
UCP209 is the next smaller size in the same series on this site: shaft d 45 mm (5 mm less), inner ring width B 49.2 mm (2.4 mm less), centre height H 54 mm (3.2 mm less), length L 190 mm (16 mm less), bolt spacing J 146 mm (13 mm less) and overall height H0 106 mm (8 mm less), and it takes M14 bolts instead of M16.

UCP210 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 UCP210 weigh about 260 kg before packing.
The catalog lists UCP210 with a dynamic load rating of 35.0 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.

UCP210 dimensions in inches
The nearest common inch shaft size to the 50 mm bore of UCP210 is 1-15/16 in (49.21 mm), 0.79 mm smaller than the bore, so UCP210 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 |
| Centre height H | 57.2 mm | 2.2520 in |
| Base length L | 206 mm | 8.1102 in |
| Bolt hole spacing J | 159 mm | 6.2598 in |
| Overall height H0 | 114 mm | 4.4882 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 UCP210 (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 UCP210 the catalog gives 3,000 and 2,200 rpm for the two cases.
The UC210 insert in UCP210 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 UCP210 down with M16 bolts at 159 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 UCP210
The insert in UCP210 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 UCP210
FULI supplies UCP210 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 UCP210.

FAQ
What shaft size does UCP210 fit?
A 50 mm shaft (1.9685 in).
What is the difference between UCP210 and UCP211?
UCP211 is the next size up, for a 55 mm shaft, with inner ring width B 55.6 mm (4 mm more), centre height H 63.5 mm (6.3 mm more), length L 219 mm (13 mm more), bolt spacing J 171 mm (12 mm more) and overall height H0 126 mm (12 mm more). Choose UCP211 when the shaft is larger or the load is higher; the housings are not interchangeable.
Which insert fits UCP210?
The UC210 insert (50 × 90 × 51.6 mm). It is sold on its own for replacement.
UCP210 or UCF210: which should I use?
Both hold the same UC210 insert on a 50 mm shaft. UCP210 is a pillow block unit (d 50 · H 57.2 · J 159 mm); UCF210 is a square flange unit (d 50 · L 143 · J 111 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 UCP210 weigh?
About 2.6 kg in FULI's catalog; 100 pieces weigh about 260 kg before packing.
Does UCP210 come as a complete unit or insert only?
UCP210 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.
