The SKF PER.RYY series Y-bearing is an insert with a spherical outer ring and set screw fixing system. It is used in split plummer block or pillow block housings for rotating shafts in transmission equipment. Its sealed design makes it suitable for environments with dust or moderate humidity. At MR Accesorios Industriales we supply this SKF line, an official brand we represent, and we advise you to choose the correct size for your application.

The PER.RYY designation is read as a family of inserts: the letters PER indicate the type of Y-bearing with spherical outer ring, the R refers to the contact seal, and YY indicates design variants in the cage or the fixing system. The numbers in between, as in PER.203RYY2, PER.205RYY3, PER.207RYY60 or PER.5203RYY2, identify shaft diameters and construction versions. Each numeric suffix can change the bore diameter, the width or the type of screw, so it is advisable to verify the full part number before ordering.

These bearings are mounted in split plummer block, pillow block or flanged housings, and are common in belt conveyors, packaging lines, mixers, fans and agricultural machinery. In Argentina you will find them in food plants, meat processing plants, quarries and maintenance workshops. Their spherical outer ring compensates for small misalignments between the shaft and the housing, which simplifies mounting on welded or folded sheet metal structures.

To select the insert, take into account the shaft diameter, the type of load and the environmental conditions. The R seal protects against dust and splashes, but if there is pressurized water or fine particles, additional seals should be evaluated. During mounting, verify that the shaft is clean and free of burrs, tighten the set screws on the flat face of the shaft and check the alignment of the housing. Factory lubrication is usually sufficient for the service life, but in demanding applications it may require relubrication.

Regarding equivalences, Y-bearings are interchangeable between brands if the main dimensions, type of fixing and sealing match. It is not enough for the shaft diameter to be the same: the total width, the distance between screws and the radius of the outer ring must be compared. Part numbers from different brands may look similar but differ in tolerances or materials. If in doubt, send us the shaft and housing dimensions and we will help you find the right replacement.
