The INA GRA-NPP-B series Y-bearing (insert bearing) is a sealed bearing unit with an extended inner ring, designed to be mounted directly in split plummer block or pillow block housings. It is used in equipment that requires smooth rotation and protection against dust and moisture, such as conveyors, fans and agricultural machinery. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, and helps you choose the correct part number for your application.

The GRA-NPP-B series designation is read in blocks: GRA identifies the family of Y-bearings with an extended inner ring; the number that follows, as in GRA010, GRA012 or GRA104-206, indicates the bore diameter and the locking variant. The NPP suffix indicates double sealing, and B the outer ring design. The AS2/V closure defines the seal type and factory lubrication. That is why, when ordering a replacement, it is best to provide the complete part number, not just the number.

These inserts are mounted in pillow block, flange or take-up housings and appear in belt conveyors, mixers, fans, screens and agricultural equipment. In the Argentine market they are found in food, cement, aggregate and water treatment plants, where an environment loaded with dust or moisture demands a protected bearing. They are also used in old machines that are repaired frequently, because the insert can be replaced without replacing the entire housing.

To select correctly, first look at the shaft diameter and the inner ring locking type: some have set screws, others an eccentric collar. The NPP seal is double and retains grease while blocking contaminants; if the equipment works with pressurized water, consider additional protection. During mounting, align the housing, tighten the screws with the correct wrench and verify that the inner ring is properly secured to the shaft. Lubricate only if the bearing is relubricable and follow the manufacturer's recommendation.

As for equivalents, Y-bearing inserts are interchanged between brands by dimensions and locking type, not by the complete part number. An insert with the same dimensions and similar sealing can replace another, but the suffixes, internal clearance and locking system change. Therefore, before replacing, compare bore diameter, width, seal type and locking method. If you have doubts, send a photo or the original part number and we will verify it with you.
