The INA RA-NPP-B series Y-bearing is an insert with a spherical outer ring and set screws to lock onto the shaft, designed to be mounted in split or pillow block housings. It is used in equipment where the shaft rotates on simple supports and slight misalignments need to be compensated. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, with technical advice to choose the correct part number for your application.

The RA-NPP-B series designation is read in parts: RA identifies the Y-bearing series with spherical outer ring; the number that follows indicates the shaft diameter, and when a second number separated by a hyphen appears (as in RA104-206-NPP-B) it corresponds to the outer diameter of the insert. The NPP suffix indicates double contact sealing, and the final B distinguishes the inner ring design. Thus, RA100-NPP-B and RA108-NPP-B share the series but differ in shaft size.

These bearings are used in belt conveyors, bucket elevators, mixers, mills, packaging lines and process equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed, meatpacking and cement industries, where split housings make mounting and maintenance easier without dismantling the entire shaft. They are also found in road machinery and material handling equipment.

To select the correct part number, take into account the shaft diameter and the type of housing where it will be seated. The NPP seal protects against dust and splashes, but it does not replace proper lubrication: check that the grease is compatible with the temperature and speed conditions. During mounting, align the housing and tighten the set screws onto the shaft without striking the insert. Excessive misalignment shortens service life even if the outer ring is spherical.

INA Y-bearings are interchangeable with those of other European brands that use equivalent designations, such as the YAR, YET or GRA series from other manufacturers. Interchangeability depends on shaft dimensions, outer diameter and insert width, not only on the part number. If you need to replace an existing bearing, send us the measurements or the part number stamped on the insert and we will confirm the available equivalent.
