The SKF XGRAE NPPB series Y-bearing is a sealed insert with an extended inner ring, made to fit into split plummer block housings or tensioners. It handles combined loads and works in dusty, humid or splash-prone areas, as well as in equipment where alignment is not perfect. MR Industrial Accessories supplies this series as part of its SKF bearing line.
The code tells you what you are holding. XGRAE marks a Y-bearing with an extended inner ring and a particular sealing and locking layout. The digits that follow, as in XGRAE30NPPB or XGRAE35NPPB, give the bore diameter. NPPB means two contact lip seals, which keep grease in and contaminants out. Reading the designation this way lets you order the exact replacement without guesswork.
These inserts show up in belt conveyors, bucket elevators, mixers, mills, packaging equipment and agricultural machinery. They also appear in washing lines and cold tunnels, where moisture makes reliable sealing essential. As Y-bearings, they are the standard pick when the bearing mounts on a shaft and sits in a support that offers some self-aligning capability.
Selection starts with the shaft diameter and the housing type. Because NPPB is a contact seal, the shaft surface must be in good condition or the lip can be damaged. During mounting, apply force to the inner ring only; never strike the outer ring or the seals. Factory lubrication normally covers the service life, though very dirty or wet conditions may call for periodic relubrication. Housing alignment also affects how the bearing performs.
When you look for equivalents, remember that every manufacturer uses its own nomenclature. A Y-bearing with the same dimensions and sealing type may exist in other brands, but the suffixes will not always match. Bore diameter alone is not enough: check the inner ring width, the locking method and the sealing class. If anything is unclear, send the full code and the shaft dimensions, and we will help you identify the right option.

Frequently asked questions
- What does the NPPB suffix mean on an SKF Y-bearing?
- NPPB indicates two contact lip seals, one on each side. They retain lubrication and block dust and moisture, so the bearing suits demanding environments. The shaft must be in good condition to avoid damaging the lip during mounting.
- How do I choose the right Y-bearing for my application?
- Start with the shaft diameter and the housing type. Then confirm the sealing and locking your equipment needs. For heavy contamination, contact seals such as NPPB are the choice. If speed is high, ask us about alternatives. Send your data and we will advise.
- Do SKF Y-bearings have equivalents in other brands?
- Yes, other manufacturers offer Y-bearings with similar dimensions, but codes and suffixes differ. To find an equivalent, compare diameter, width, sealing type and locking method. Do not rely on the number alone. Send us the original code and we will help you find the right option.
