For shafts from 3/4" to 1-1/2", the NTN SUC series insert bearing provides a reliable set-screw mounting solution. Designed with an extended inner ring, it pairs with split plummer block housings and other bearing units. This series suits power transmission, conveying, and general machinery where quick installation and replacement are priorities.
The part number breaks down into two parts: the SUC prefix denotes an insert bearing with extended inner ring and set screws, while the following digits give the shaft size in sixteenths of an inch. For example, SUC204-12 fits a 3/4" shaft, SUC205-16 fits 1", SUC206-19 fits 1-3/16", SUC207-20 fits 1-1/4", SUC207-23 fits 1-7/16", and SUC208-24 fits 1-1/2". The FG1 suffix indicates the sealing and factory lubrication configuration.
Common applications include belt conveyors, bucket elevators, mixers, fans, pumps, and equipment in the food industry. The set-screw design allows mounting without a press, and the extended inner ring improves shaft contact. In maintenance, the bearing can be removed and replaced without disturbing the housing, reducing downtime.
When selecting a bearing, confirm the shaft diameter, load type (radial, axial, or combined), and environmental conditions. The FG1 seals retain grease and block contaminants. During installation, align the shaft and housing, then tighten the set screws to the recommended torque. Factory lubrication is adequate for most conditions; severe environments may require periodic relubrication.
NTN SUC bearings are interchangeable with other brands using similar designations such as UC, YAR, or GRA, provided the dimensions and fixing method match. Verify shaft diameter, inner ring width, and sealing system before substituting. Send the original part number for help identifying a compatible alternative.

Frequently asked questions
- What does the FG1 suffix mean on NTN SUC bearings?
- FG1 indicates specific sealing and lubrication features. These bearings come with contact seals that retain grease and protect against dust and moisture, suitable for general industrial use.
- How do I determine the correct SUC bearing for my shaft?
- Measure the shaft diameter in inches. The digits after SUC give the size in sixteenths: SUC204-12 is for 3/4", SUC205-16 for 1", SUC206-19 for 1-3/16", and so on. Contact us with your measurement for assistance.
- Are NTN SUC bearings compatible with other brands?
- Yes, they are interchangeable with brands using similar designations like UC or YAR, if dimensions and set-screw fixing match. Provide the original part number to confirm compatibility.
