The INA Y-bearing (insert bearing) is an insertable bearing with a spherical outer ring, designed to be mounted in split plummer block housings or sheet metal housings. It is used in transmission and conveying equipment where smooth rotation with slight misalignment is required. The SK-KRR-B-L-AH series includes sealing and a shaft locking system, which simplifies mounting and plant maintenance.

The designation of this series is read in blocks: SK identifies the insert family, the number that follows refers to the diameter and the housing type, and KRR indicates the double-lip seal. The B corresponds to the spherical outer ring, the L to locking by set screws and AH to the bore type or insert configuration. The long numeric suffixes distinguish sealing, tolerance or mounting variants within the same series.

These bearings are used in belt conveyors, bucket elevators, mixers, mills and process equipment in food, chemical and aggregate plants. In Argentina they are common in packaging lines, plant conveyor belts and agricultural machinery, where a dusty or humid environment requires effective sealing. Their insertable format allows the bearing to be replaced without disassembling the entire housing, which reduces downtime.

To select the insert, verify the shaft diameter and the type of housing where it will be mounted. The KRR seal protects against dust and splashes; if the equipment is washed frequently, it is advisable to review the seal variant. Locking by set screws requires controlled tightening and correct alignment between housings. Factory lubrication is usually sufficient, but in demanding applications relubrication should be scheduled. In case of misalignment, the spherical outer ring absorbs small deviations.

Insert bearings are available from different brands under their own nomenclatures, but the main dimensions usually match between manufacturers. Therefore, when looking for a replacement, the safest approach is to compare the complete part number and the shaft and housing dimensions. At MR Accesorios Industriales we can guide you on interchangeability within the SK-KRR-B-L-AH series and its variants, without that implying any claim of equivalences that have not been verified.
