The NTN UCFS3 series Y-bearing unit with insert is a 4-bolt flange mounted bearing. It is used to support rotating shafts on flat structures, with the particular feature that the flange has an elongated diamond shape, which allows the shaft position to be adjusted during mounting. It is a compact, simple-to-mount solution, widely used in transmission and conveying equipment.

The UCFS3 series designation reads as follows: UCFS identifies the 4-bolt flange housing with insert bearing; the initial 3 corresponds to the size series, and the numbers after the hyphen indicate the shaft diameter. For example, UCFS305-013D1 is for a 13/16" shaft, UCFS305-014D1 for 7/8" and UCFS305-100D1 for 1". When there is no hyphen, as in UCFS305D1, the size is metric: 25 mm. The D1 suffix distinguishes the insert version with a contact seal.

In Argentine industry, these units appear in belt conveyors, bucket elevators, mixers, screens and packaging lines. They are also found in aggregate processing equipment, food plants and irrigation systems. Their 4-bolt flange allows them to be fastened to sheet metal or profile structures, and the elongated shape makes it easier to tension chains or belts. MR Accesorios Industriales sells this line for replacement and new projects.

To choose well, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert comes lubricated from the factory; in dusty or humid environments, it is advisable to choose seals with greater tightness. When mounting, rest the flange on a flat, clean surface, tighten the bolts in a cross pattern and check the alignment of the shaft with the equipment. Periodic lubrication and moderate retightening extend service life.

NTN UCFS3 series units are interchangeable with other brands that use the same dimensional nomenclature. If the customer brings another firm's part number, we can indicate the exact equivalent. There are also variants with different types of locking of the insert to the shaft (set screws, taper or eccentric). To ensure compatibility, the best approach is to provide the complete part number or the shaft and flange hole dimensions.
