A Y-bearing insert is a ball bearing built with a spherical outer ring and a shaft locking system, made to sit inside split plummer block or flanged housings. The INA KRR-AH line fits equipment where the shaft turns and the unit must stay compact and self-aligning. MR Industrial Accessories supplies this series and helps you match the right variant to the job.

Reading the code takes a moment. Start with the leading size number, then the letters KRR, then the AH suffix with its two digits, as in 203-XL-KRR-AH02 or 207-XL-KRR-AH03. The number sets the bearing size, KRR marks the spherical outer ring design with shaft locking, and AH plus two digits separates the sealing or locking versions that share a series. Quote requests move faster when you send the full designation printed on the equipment.

Typical mounting points are pillow block, flanged and take-up housings. You will see these inserts on conveyors, packaging lines, industrial washing equipment, fans and agricultural machinery, and maintenance crews keep them on hand for food plants, meat processing operations, tanneries and general repair shops. Because the outer ring is spherical, small misalignments in the housing are absorbed, which keeps installation simple on welded frames and sheet metal structures.

Selection comes down to three inputs: shaft diameter, locking method and the sealing the surroundings demand. The AH suffixes generally mark differences in seal or adjustment design, so dusty, wet or frequently washed areas call for a tighter seal. At mounting, check that the housing is aligned, the shaft is clean and lubrication is in order. These inserts ship pre-lubricated, yet a quick check before start-up is still worthwhile.

Cross-brand replacement only works when the main dimensions, locking style and sealing all line up. A matching shaft diameter by itself proves nothing, since inner ring width, outer profile and the position of the locking holes also decide fit. Run the complete designation past a specialist before ordering. Our team can point you to an equivalent among the brands we carry.
