The NTN ASFB2 series 2-bolt flange Y-bearing unit is an assembled unit that combines a cast iron housing with an insert bearing, ready to mount on a flat surface. It is used to support rotating shafts in equipment where the mounting must be compact and the shaft is perpendicular to the flange. MR Accesorios Industriales sells this line as a brand MR sells, with more than 80 years of experience in the field.

The ASFB2 series designation is read in blocks. The letters ASFB identify the 2-bolt flange housing family; the first number indicates the insert bearing size and the final letter D indicates the version with a specific seal. For example, ASFB201D1 corresponds to a housing for a size 201 insert bearing, while ASFB201-008D1 includes the shaft diameter in inches (008 equals 1/2"). Likewise, ASFB202-009D1 and ASFB202-010D1 cover 9/16" and 5/8" shafts respectively, and ASFB204-012D1 goes up to 3/4". Knowing this logic lets you order the exact part number.

In Argentine industry, these housings appear in belt conveyors, screens, mixers, fans and packaging lines. They are also found in agricultural equipment, food plants and water treatment systems. Their 2-bolt flange format makes mounting on sheet metal or steel structures easy, with the shaft passing through and the insert bearing already aligned. As a sealed unit, it requires little maintenance and withstands dusty or moderately humid environments.

To select the housing, check the shaft diameter and the insert bearing locking type (set screw, eccentric or adapter). The ASFB2 series accepts moderate radial and axial loads; if the shaft runs with misalignment, the insert has internal clearance that partially compensates for it. During mounting, rest the flange on a clean, flat surface, tighten the bolts in a cross pattern and check that the shaft turns without effort. Lubrication comes from the factory; in service, follow the manufacturer's recommendations to relubricate if the insert has a grease fitting.

Interchange between Y-bearing housing brands is handled by standardized dimensions: a 2-bolt flange housing with a 20 mm shaft insert bearing can be interchanged with another brand that respects the same mounting dimensions and diameter. To do this, compare the drawings or send the main dimensions. At MR Accesorios Industriales we tell you the compatible alternative if you bring the part number of another brand or an unidentified part. Write to us on WhatsApp with the part number or model you need and we'll quote it shortly.
