The NTN UCC housing with insert bearing arrives as one cartridge assembly: the insert is already seated in the housing and the mounting dimensions are established. It supports rotating shafts in equipment that has a cylindrical housing seat, keeping the assembly aligned and the bearing covered. MR Industrial Accessories LLC supplies this line to customers in the United States and Latin America, and quotes part numbers by WhatsApp or email.

Reading a UCC part number is straightforward once you know the blocks. The letters UCC denote the cartridge housing with insert bearing. The digit that follows tells you the size series: UCC2 is light, UCC3 is medium. The next digits give the shaft diameter, and the D1 suffix marks an insert design variant. So UCC201D1 and UCC201-008D1 belong to the UCC2 series, as does UCC204-012D1. When a hyphen appears, the three digits after it state the diameter in inches. With those pieces you can identify the complete unit.

You will find these cartridges in conveyors, belts, elevators, mixers, blowers and process lines. They suit food plants, cement operations, cold storage, tanneries and maintenance shops. The cartridge shape lets you mount the unit in a machined cylindrical seat, so the shaft is supported and the bearing is protected. It is a practical choice when the housing must sit inside a frame or box and there is no space for a flange or pillow block.

Selection depends on shaft diameter, load type and operating environment. The insert seal determines whether the unit handles dust, water or frequent washdowns. Lubrication is applied at the factory and should be checked according to the duty cycle. At mounting, confirm the seat is clean and within tolerance, and slide the shaft in without impact. Aligning units with each other avoids stressing the insert and extends assembly life. On equipment with vibration, verify the set screws remain tight.

NTN UCC units interchange with other brands that share the cartridge nomenclature and shaft dimensions. What matters is the shaft diameter, the insert locking type and the housing outer dimensions. If you have a part number from another brand or an unidentified part, MR Industrial Accessories LLC can identify the compatible equivalent. You can also ask about the UCC2 or UCC3 series for the size you need.
