The INA RAL-NPP series Y-bearing is an insert with extended inner ring and NPP double-sided seal, designed to be mounted in split plummer block or flanged housings. It is used in transmission and conveying equipment where ease of mounting and protection against contaminants are key. MR Accesorios Industriales supplies this INA line in Buenos Aires, Argentina, and advises you on choosing the correct part number for your application.

The RAL-NPP designation is read in parts: RAL identifies the series of inserts with extended inner ring and set screw locking system; the number that follows —as in RAL012-NPP— indicates the insert size; and the suffix NPP indicates the double-sided seal with labyrinth and elastomer lip seal. This seal protects against dust, water and particles, and is decisive for service life in demanding environments.

These inserts are mounted in split plummer block, flanged or take-up housings to form Y-bearing units. They are found 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 meat industry, in feed mills and in packaging lines, where cleanliness and quick mounting matter as much as load capacity.

To select the insert, check the shaft diameter, the housing type and the working conditions. The NPP seal is suitable for environments with moisture or dust; if there are frequent washdowns, additional protections should be evaluated. During mounting, align the housing and tighten the set screws onto the shaft with the appropriate wrench, without striking the outer ring. Lubricate according to the duty cycle and check clearance and alignment to avoid parasitic loads.

INA RAL-NPP inserts are interchangeable with other brands that use the same dimensional and locking nomenclature, although the seal, inner ring tolerance or locking type may vary. Before replacing, compare the complete part number and the critical dimensions. If you have doubts, send us the part number engraved on the bearing or the shaft and housing measurements: at MR Accesorios Industriales we help you identify the equivalent.
