The Y-bearing with insert bearing is an assembled unit that combines an insert bearing unit with a four-bolt flange housing. It is used to support rotating shafts on metal or concrete structures, with fixed alignment and quick mounting using bolts. The NTN UCFG2 series covers standard metric sizes in transmission and conveying equipment. MR Accesorios Industriales sells this line as part of its bearing housing catalog.

The UCFG2 designation is read in blocks: UCFG identifies the type of four-bolt flange housing with insert bearing; the initial 2 of the series groups the metric sizes of this family. Examples range from UCFG201D1 to UCFG208D1, where the last two digits indicate the size within the series. The D1 suffix distinguishes the sealing and internal configuration variant that NTN applies to these units. To order the exact code, send us the complete designation that appears on the plate or drawing.

These housings are seen in belt conveyors, packaging lines, mixers, blowers and transmission lines in food, chemical and materials plants. In Argentina they are common in grain handling equipment, aggregate processing plants and machines for the wood industry. The four-bolt flange allows them to be fixed to structural profiles or plates with simple alignment, and the insert bearing accommodates slight misalignments typical of mounting. They are also chosen when a complete unit needs to be replaced without machining the shaft.

To select correctly, take into account the shaft diameter, the type of load (radial, axial or combined) and environmental conditions. The insert seal defines protection against dust, water or chips: in dirty environments a variant with an additional seal is advisable. Factory lubrication can be replenished through the grease fitting if the equipment allows it; check that the passage is accessible. During mounting, rest the flange on a flat surface, tighten the bolts in a cross pattern and check that the shaft turns without effort before starting up.

Four-bolt flange bearing units are available from several brands with their own nomenclatures. Dimensional interchangeability is not always direct: the distance between holes, flange diameter or insert fixing type may vary. When replacing a unit, compare those dimensions and the bearing locking system. If you have the code from another brand, write to us and we will indicate the equivalent NTN reference or the compatible alternative that best suits your equipment.

MR Accesorios Industriales sells the NTN bearing housing line and will quote the code you need. Send us via WhatsApp the complete designation (for example, UCFG205D1) or the shaft and flange measurements, and we will respond promptly with the corresponding reference. If you are looking for a variant that does not appear in the list, write to us anyway: we will source it or indicate the compatible option.
