The INA Y-bearing series NPP-B is a bearing insert with a spherical outer ring, a contact seal and screw locking. It fits into split plummer block or flanged housings and is used where shafts turn at moderate speeds and the lubricant must be shielded from dust and moisture. MR Industrial Accessories supplies this series to customers in the United States and Latin America, offering technical guidance to match the correct size.

The part number tells you the bore size and design details. The first digits give the bore diameter: for instance, 201-XL-NPP-B has a 12 mm bore, 205-XL-NPP-B has a 25 mm bore, and 208-XL-NPP-B has a 40 mm bore. The NPP part of the code means a double contact seal, while the final B indicates the screw locking method on the inner ring. Understanding this structure helps you order the exact bearing without confusion.

These inserts are common in conveyors, packaging machines, industrial washers, mixers and ventilation systems, as well as in agricultural equipment and processing lines where dust or moisture is present. Because they are inserts, they mount into split plummer block, flanged or take-up housings, which makes replacement and alignment easier on long or hard-to-reach shafts.

When selecting a Y-bearing, consider the shaft diameter, the load type and the operating environment. The NPP-B contact lip seal protects against particles and splashes, but if there is abundant water or frequent washdown, you may need to evaluate additional seals. During mounting, clean the shaft, ensure it is free of burrs, and tighten the locking screws with the correct wrench. Proper lubrication and careful alignment help extend the service life of the insert.

Insert bearings from different brands often have similar nomenclatures. When comparing, verify that the main dimensions, locking type and sealing match, because a code from another brand does not always directly replace an NPP-B. Our team can help you check compatibility and find suitable options for your equipment.
