The SKF PER.BB Y-bearing is a bearing unit with spherical insert, designed to be mounted on shafts and housed in split plummer block or pillow block housings. It is used in equipment where misalignment must be absorbed and rotation maintained with retained lubrication. MR Accesorios Industriales supplies this line, with technical advice to choose the correct variant according to the equipment and working environment.

The designation PER.BB…RYY… is read in blocks: PER.BB identifies the category of Y-bearings with spherical insert; the numbers that follow indicate the bore size and the dimension series; R indicates that the insert has a groove or retention feature; YY refers to the seal type, and the final digit distinguishes design variants. A specific example is PER.BB203RYY2, where the full part number places the order without ambiguity. To request a quote, provide the part number as it appears on the plate or on the old bearing.

These Y-bearings are used in belt conveyors, bucket elevators, mixers, mills, screens and process equipment. In Argentina they are common in food plants, cement plants, cold storage facilities, tanneries and agro-industrial sites, where dust, humidity or washdowns require reliable sealing. They also appear in fans and low-demand centrifugal pumps. The combination of spherical insert and housing allows mounting on welded structures without fine machining.

To select correctly, take into account the shaft diameter, the type of load — radial, axial or combined — and the environmental conditions. The YY seal protects against dust and splashes; if there are frequent washdowns, it is advisable to verify the resistance of the seal material. The spherical insert allows for some initial misalignment, but housing alignment remains key to service life. Lubrication must be the one indicated for the working temperature, and the set screws are tightened onto the shaft with the appropriate wrench, without hammering.

Regarding equivalences, Y-bearings are interchangeable between brands by series number and dimensions, but not all seals or tolerances are the same. When replacing, compare the full part number, the type of shaft locking and the shape of the insert. If the original equipment has a variant with a groove or a specific seal, it is advisable to maintain that configuration. MR Accesorios Industriales can advise you on interchangeability without compromising the operation of the assembly.

If you have the part number PER.BB203RYY2 or any other from the line, send it on WhatsApp to MR Accesorios Industriales along with a photo of the bearing and the housing. With that data we verify the variant and send you the quote. We can also check whether the seal or locking requires a different design for your application.
