For transmission and conveying setups that need smooth rotation and can tolerate slight misalignment, the INA Y-bearing insert with a spherical outer ring is a practical choice. It fits into split plummer block housings or sheet metal housings. The SK-KRR-B-L-AH series comes with sealing and a shaft locking system, which simplifies mounting and routine maintenance.
Reading the code helps you identify the right insert. SK marks the insert family; the following number covers diameter and housing type. KRR points to the double-lip seal. B means spherical outer ring, L stands for locking via set screws, and AH refers to the bore type or insert configuration. Longer numeric suffixes separate sealing, tolerance, or mounting variants within the series.
These bearings appear in belt conveyors, bucket elevators, mixers, mills, and process equipment across food, chemical, and aggregate plants. In dusty or humid conditions, the KRR seal provides protection against dust and splashes. Because the insert can be replaced without dismantling the entire housing, downtime is reduced.
To select an insert, check the shaft diameter and the housing type. If equipment is washed frequently, review the seal variant. Locking by set screws calls for controlled tightening and proper alignment between housings. Factory lubrication usually suffices, but in demanding applications schedule relubrication. The spherical outer ring absorbs small misalignments.
Different brands offer insert bearings under their own nomenclatures, yet main dimensions often match. For a replacement, compare the complete part number and the shaft and housing dimensions. We can guide you on interchangeability within the SK-KRR-B-L-AH series and its variants.

Frequently asked questions
- What does KRR mean in this bearing?
- KRR indicates the insert sealing type, with a double lip, which protects against dust and splashes. It is common in industrial environments with moderate contamination.
- How do I choose the right Y-bearing for my equipment?
- You need the shaft diameter, the housing type, and the working conditions. With the complete insert part number or the housing dimensions, we can guide you to the right variant.
- Can I replace a Y-bearing from another brand with this INA one?
- In many cases yes, because the main dimensions are usually compatible between manufacturers. Still, compare the part number and the shaft and housing dimensions before mounting.
