UCP207 interchange by brand
UCP207 is a housed unit: a UC207 insert bearing in a P207 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 | Designation |
|---|---|
| SKF | UCP 207 |
| Timken | UCP207 |
| NTN | UCP207D1 |
| Koyo | UCP207 |
Same size code; NTN adds D1 after the number. Confirm housing bolt spacing.

UCP207 compared with nearby sizes and housings
UCP207 is a pillow block unit that holds the UC207 insert on a 35 mm shaft: centre height H 47.6 mm, base length L 167 mm and overall height H0 93 mm with M14 bolts.
The same 207 size is also made as UCF207 (square flange unit, d 35 · L 117 · J 92 mm) and UCFL207 (oval flange unit, d 35 · L 161 · J 130 mm). All of them take the same UC207 insert, so a worn insert can be changed without changing the housing type.
UCP208 is the next larger size in the same series on this site: shaft d 40 mm (5 mm more), inner ring width B 49.2 mm (6.3 mm more), centre height H 49.2 mm (1.6 mm more), length L 184 mm (17 mm more), bolt spacing J 137 mm (10 mm more) and overall height H0 100 mm (7 mm more).
UCP206 is the next smaller size in the same series on this site: shaft d 30 mm (5 mm less), inner ring width B 38.1 mm (4.8 mm less), centre height H 42.9 mm (4.7 mm less), length L 165 mm (2 mm less), bolt spacing J 121 mm (6 mm less) and overall height H0 83 mm (10 mm less).

UCP207 weight, load ratings and speed
FULI's catalog gives about 1.6 kg for the complete unit, housing and insert together, so 100 pieces of UCP207 weigh about 160 kg before packing.
The catalog lists UCP207 with a dynamic load rating of 25.7 kN and a static load rating of 15.3 kN. Its speed limits depend on the shaft tolerance: 4,000 rpm on a js7 or j7 shaft and 3,000 rpm on an h7 shaft. A closer shaft fit holds the inner ring more evenly, which is why the js7 / j7 figure is higher.

UCP207 dimensions in inches
The nearest common inch shaft size to the 35 mm bore of UCP207 is 1-3/8 in (34.93 mm), 0.07 mm smaller than the bore, so UCP207 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 | 35 mm | 1.3780 in |
| Centre height H | 47.6 mm | 1.8740 in |
| Base length L | 167 mm | 6.5748 in |
| Bolt hole spacing J | 127 mm | 5.0000 in |
| Overall height H0 | 93 mm | 3.6614 in |
| Insert width B | 42.9 mm | 1.6890 in |
Converted at 1 in = 25.4 mm and rounded to four decimals. The bearing itself is made to the millimetre sizes.
Mounting UCP207 (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 UCP207 the catalog gives 4,000 and 3,000 rpm for the two cases.
The UC207 insert in UCP207 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 UCP207 down with M14 bolts at 127 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 UCP207
The insert in UCP207 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 UCP207
FULI supplies UCP207 as a complete unit, or the UC207 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 UCP207.

FAQ
What shaft size does UCP207 fit?
A 35 mm shaft (1.3780 in).
What is the difference between UCP207 and UCP208?
UCP208 is the next size up, for a 40 mm shaft, with inner ring width B 49.2 mm (6.3 mm more), centre height H 49.2 mm (1.6 mm more), length L 184 mm (17 mm more), bolt spacing J 137 mm (10 mm more) and overall height H0 100 mm (7 mm more). Choose UCP208 when the shaft is larger or the load is higher; the housings are not interchangeable.
Which insert fits UCP207?
The UC207 insert (35 × 72 × 42.9 mm). It is sold on its own for replacement.
UCP207 or UCF207: which should I use?
Both hold the same UC207 insert on a 35 mm shaft. UCP207 is a pillow block unit (d 35 · H 47.6 · J 127 mm); UCF207 is a square flange unit (d 35 · L 117 · J 92 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 UCP207 weigh?
About 1.6 kg in FULI's catalog; 100 pieces weigh about 160 kg before packing.
Does UCP207 come as a complete unit or insert only?
UCP207 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.
