The SKF XGGRA NPPB is a Y-bearing insert with a spherical outer ring and two set screws, made to fit split plummer block or pillow block housings. It handles moderate radial and axial loads and tolerates some misalignment, which suits equipment where shaft alignment is not perfect. The NPPB seal shields the bearing from dust and moisture.
Reading the code helps you confirm the right part. XGGRA is the Y-bearing series with its own sealing and locking arrangement; NPPB identifies the seal, a double-lip design with extra protection. The numeric portion of the part number relates to the shaft diameter, and some references carry a suffix for a dimensional or mounting variant. Check the complete number on the equipment nameplate or in the manual before ordering.
These inserts show up in food processing, meatpacking, ceramics, tanneries and agricultural work, among other sectors. Typical positions include belt conveyors, bucket elevators, mixers, fans, machine tools, centrifugal pumps and screw compressors. Because the spherical outer ring compensates for misalignment, they work well on long shafts or mountings where perfect alignment is difficult to achieve.
Selection comes down to three things: shaft diameter, the load case (radial, axial or combined) and the operating environment. The NPPB seal resists dust and moisture, but for corrosive liquids or extreme temperatures it is worth reviewing other options. At mounting, keep the housing clean and free of burrs, apply the specified lubricant, verify axial clearance and tighten the set screws with a torque wrench so the shaft is not deformed.
On interchangeability, SKF Y-bearings can be replaced with other brands that follow the same dimensional standard. Seals are not identical across manufacturers, though, and the NPPB design has its own features. When substituting, compare the main dimensions plus the seal type and load capacity, not just the bore. Our team can help you identify a suitable alternative.

Frequently asked questions
- What does the NPPB suffix indicate on this bearing?
- NPPB denotes a double-lip seal with additional protection against dust and moisture, suited to moderately contaminated environments. Nomenclature differs between manufacturers, so confirm the full part number.
- Can this bearing take axial loads?
- Yes. Y-bearings such as the XGGRA NPPB accept moderate radial and axial loads. For very high axial loads, another bearing type should be evaluated. Share your application data and we will advise.
- How do I determine the bearing size I need?
- Size follows the shaft diameter and the numeric code of the bearing; the number in the code corresponds approximately to the shaft diameter in millimeters. Measure the shaft with a caliper and send us the part number from the old bearing.
