The UCFA2 housing with insert bearing is a 4-bolt flange mounted bearing unit. It is used to support rotating shafts on structures with a flat surface, where the flange is fastened with four bolts. The NSK UCFA2 series combines a cast housing with a ball insert bearing, already aligned and lubricated, ready to mount. It is a compact solution for power transmission in equipment that requires firm support and easy replacement.

The UCFA2 designation is read as follows: UCFA identifies the 4-bolt flange housing, 2 indicates the diameter series, and the number that follows —as in UCFA201D1 or UCFA204-012D1— defines the bore size of the insert bearing. The suffix D1 distinguishes the insert execution. In codes with a hyphen, such as UCFA201-008D1, the number after the hyphen corresponds to the bore size in inches. Thus, UCFA201D1 and UCFA201-008D1 share the housing but differ in bore diameter.

These housings are seen in belt conveyors, mixers, blowers, exhaust fans, packaging lines and process equipment in food, chemical and materials plants. In Argentina they are common in the meat industry, flour mills, aggregate processing plants and packaging lines, where a robust flange support with quick replacement is needed. They also appear in agricultural machinery and materials handling equipment.

To choose the right housing, take into account the shaft diameter, the type of load and the environmental conditions. The insert's sealing defines whether it withstands dust, water or frequent washdowns. Alignment between the flange and the shaft prevents lateral stresses. Insert lubrication is permanent in most cases, but it is advisable to check the clearance and the condition of the seals during mounting. Fasten the flange with the four bolts on a flat surface and verify smooth rotation before start-up.

If you need to replace a housing from another brand, the safest approach is to compare the main dimensions: shaft diameter, distance between flange holes and overall height. The NSK UCFA2 series can usually be interchanged with other brands that use the same nomenclature, but always verify the dimensions. At MR Accesorios Industriales we quote the exact code shown on your equipment or the measurement you need, no hassle.
