The 4-bolt flange housing with NTN insert bearing is a mounted unit that combines a cast iron housing with a self-aligning insert bearing. It is used to support rotating shafts on flat structures, where the flange is fastened with four bolts. It is a compact, easy-to-mount solution for power transmission in industrial equipment. MR Accesorios Industriales sells this NTN line in Buenos Aires, Argentina.

The UELF designation identifies the 4-bolt flange housing series. The numbers that follow indicate the size: for example, UELF204-012D1W3 corresponds to a housing for a 12 mm shaft, while UELF205-100D1W3 is for a 1 inch shaft. The suffix D1 indicates the insert type and W3 a sealing variant. In the examples with a hyphen, such as UELF206-101D1W3, the number after the hyphen specifies the exact shaft size in inches or millimeters. Knowing how to read this allows you to order the correct code.

These housings are used in conveyors, belts, elevators, mixers, mills and process equipment. In Argentina they are common in food, cement and mining plants and in the agro-industrial sector, where the 4-bolt flange makes mounting on sheet metal or structure easier. They are also used in road machinery and pumping equipment. Their self-aligning design tolerates small misalignments and simplifies maintenance.

To select the housing, verify the shaft diameter and the type of fastening required. The W3 seal protects against dust and moisture, suitable for environments with particles. The insert comes pre-lubricated, but in severe applications lubrication should be checked periodically. During mounting, make sure the flange sits well and that the bolts are tightened evenly to avoid deformation. Shaft alignment with the bearing is key to extending service life.

NTN housings are interchangeable with those from other brands that follow the same dimensional nomenclature. If you have a code from another brand, we can tell you the equivalent. We can also quote the replacement if you send us the shaft dimensions and the distance between the flange holes. Interchangeability is based on standardized dimensions, not on the code itself.

If you need a 4-bolt flange housing with insert bearing, write to us on WhatsApp with the UELF code or your shaft dimensions. At MR Accesorios Industriales we quote you promptly and advise you so you choose the correct variant.
