The SKF Y-bearing with insert bearing is a ready-to-mount unit that combines an insert bearing with a cast iron or sheet steel housing. It is used to support rotating shafts in equipment where simple alignment and permanent lubrication are required. MR Accesorios Industriales carries this line as an official brand, with more than 80 years of experience in industrial distribution.
The designation FYTBK identifies an oval flanged Y-bearing with insert bearing. The numbers that follow, as in FYTBK 504 or FYTBK 505, indicate the size of the insert bearing and the shaft for which it is intended. The series covers several sizes: FYTBK 504, FYTBK 505, FYTBK 506 and FYTBK 507 are specific examples of that progression. Each part number refers to a specific combination of housing and bearing, and it is advisable to verify the shaft size before choosing.
These bearings are used in conveyors, belts, elevators, mixers, fans and agricultural or food machinery. In Argentina they are common in food plants, meat processing plants, mills and metalworking shops, where quick mounting and easy relubrication are key. Being self-aligning units, they tolerate small misalignments and simplify maintenance in equipment that works with dust, humidity or frequent washdowns.
To select the bearing, take into account the shaft diameter, the type of load and the environmental conditions. Check the insert bearing's sealing: versions with a contact or lip seal offer better protection against dust and water. The internal clearance and lubrication are already defined at the factory, but it is advisable to check that the housing is properly seated and that the locking screws are tightened to the correct torque. Aligning the shaft with the housing prevents stress and extends service life.
SKF Y-bearings with insert bearing are interchangeable with those of other brands that follow the same standardized dimensions. When replacing, compare the complete part number and the main dimensions: shaft diameter, distance between holes and center height. Not all series have the same tolerances or seals, so confirm the equivalence with the supplier. MR Accesorios Industriales can advise you if you have doubts about interchangeability.
