The INA RALE-XL-NPP-B is a single-row insert Y-bearing with a spherical outer ring and set screw locking. It mounts in split or flanged housings to support rotating shafts in power transmission equipment. MR Industrial Accessories supplies this INA line from Miami, serving customers across the United States and in several Latin American countries, with technical guidance to select the right size and variant.

The code breaks down into meaningful blocks: RALE is the insert bearing series with a spherical outer ring, XL denotes the optimized version, NPP stands for double contact seals, and B indicates set screws on the inner ring. The number that follows the letters gives the shaft diameter in millimeters, as seen in RALE20-XL-NPP-B, RALE25-XL-NPP-B, and RALE30-XL-NPP-B. Reading the code this way helps you order the exact part without mix-ups.

Typical applications include conveyors, belts, elevators, mixers, fans, and agricultural machinery. In food processing, cement, aggregate, and waste treatment plants, split housings simplify assembly and replacement. The spherical outer ring compensates for minor misalignment between shaft and housing, which helps maintain service life in equipment subject to vibration or imperfect mounting.

When selecting a bearing, confirm the shaft diameter and housing type. The NPP double-lip seal guards against dust and moisture; in very dirty conditions or with frequent washdowns, check lubrication and seal condition regularly. During mounting, align the housing and tighten the set screws on the shaft with a suitable wrench, without striking the outer ring. Proper lubrication and periodic retightening help prevent premature failures.

Y-bearings are offered by various brands under their own nomenclatures. Interchangeability is based on dimensions and locking type, not on the code itself. If you are replacing a Y-bearing from another brand, provide the shaft and housing dimensions and the sealing type. MR Industrial Accessories can help you identify the compatible INA variant for your application.
