FAQ

Question?

What does the suffix "NPP-B" signify for an INA bearing?

The "NPP-B" suffix indicates that the bearing is equipped with P-seals on both sides. These are lip seals that provide excellent protection against contamination and retain lubricant effectively, making them suitable for demanding environments.

How is this bearing locked onto the shaft?

The GRAE35-NPP-B features two set screws (grub screws) in the extended inner ring. These screws are tightened to securely lock the bearing in its position on a 35mm shaft.

Can this insert bearing be used without a housing?

No, this is an insert bearing designed to be mounted within a corresponding bearing housing (e.g., a pillow block or flange unit). The spherical outer surface allows it to self-align within the housing to compensate for initial shaft misalignments.
