This SKF Y-bearing unit combines a spherical insert with a housing, allowing it to sit on a shaft while compensating for minor misalignment. It keeps lubrication contained and rotation smooth in equipment where shafts are not perfectly aligned. MR Industrial Accessories LLC supplies this line and can help you match the exact variant to your machinery and operating conditions.

The part number PER.BB…RYY… breaks down into meaningful blocks. PER.BB marks the series of Y-bearings with a spherical insert. The following digits give the bore size and dimension series. The letter R shows that the insert includes a groove or retention detail. YY stands for the seal design, and the last digit separates different design versions. For instance, PER.BB203RYY2 is a complete reference that removes any doubt when ordering. Always quote the number exactly as it appears on the bearing or the machine plate.

Typical applications include belt conveyors, bucket elevators, mixers, mills, screens, and other process equipment. They also show up in fans and light-duty centrifugal pumps. Because the insert is spherical, you can mount the housing on welded structures without precision machining. In food plants, cement works, cold stores, tanneries, and agro-industrial sites, dust, humidity, or washdowns make reliable sealing essential.

When selecting, consider shaft diameter, load type—radial, axial, or combined—and the environment. The YY seal keeps out dust and splashes. For frequent washdowns, check that the seal material suits the cleaning agents. The spherical insert tolerates some initial misalignment, but housing alignment still determines service life. Use the lubricant specified for the operating temperature, and tighten the set screws with a proper wrench, never by hammering.

Y-bearings are generally interchangeable between brands by series number and dimensions, but seals and tolerances can differ. When replacing, compare the full part number, the shaft locking method, and the insert shape. If the original had a groove or a specific seal, keep that configuration. MR Industrial Accessories LLC can advise on interchangeability without compromising the assembly.

If you have a part number like PER.BB203RYY2 or any other from this line, send it via WhatsApp or email along with a photo of the bearing and housing.
