The SKF FYTB M Y-bearing unit with insert bearing is an assembled unit that combines an oval flanged housing unit with a Y-series insert bearing. It is used to support rotating shafts in equipment requiring quick mounting and simple alignment, such as conveyor belts, fans and agricultural machinery. MR Accesorios Industriales sells this line as an official brand, with technical advice to choose the correct part number.
The designation FYTB … M is read as follows: FYTB identifies the type of oval flanged housing with insert bearing; the number that follows, as in FYTB 503 M or FYTB 510 M, indicates the size and the shaft diameter to which it corresponds; the final M indicates the housing material, grey cast iron. The examples in the series range from 503 to 510, with variants for different shaft diameters. To confirm the exact size for your equipment, send us the complete part number and we will verify it.
These bearing units are used in industries such as food, agriculture, logistics and metallurgy. They appear in belt conveyors, bucket elevators, mixers, dryers, centrifugal fans and process equipment. In Argentina they are commonly found in milling plants, meat processing plants and animal feed factories, where quick mounting and dismounting of the insert bearing simplifies maintenance and reduces downtime.
To select the bearing unit, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert bearing comes with a seal that retains lubricant and blocks dust and humidity; verify that the seal is suitable for the environment. Mounting is done with a clean, burr-free shaft, tightening the insert with the set screws or the collar depending on the model. Proper alignment of the bearing unit is key to avoid stresses and extend service life.
SKF FYTB M bearing units are interchangeable with other brands that use the same oval flange and insert bearing nomenclature, provided the main dimensions and shaft diameter match. When replacing, compare the center height, the hole spacing and the locking type. Do not invent equivalences: if you have any doubts, ask us with the original part number and we will help you find the correct option within our product line.
