The INA SK-KRR-AH series Y-bearing (insert bearing) is an insertable bearing with a spherical outer ring and set screw locking system, designed to be mounted in split plummer block housings or in housings that seat the outer raceway. It is used in equipment where the shaft rotates and the housing remains fixed, with a need for alignment and simple disassembly. MR Accesorios Industriales carries this line as an official brand in Buenos Aires, Argentina.

The series designation is read in blocks: SK identifies the family of insert bearings with spherical outer ring; the number that follows (for example, in SK100-206-KRR-AH11) indicates the nominal shaft diameter in inches and the construction variant; KRR indicates the double-lip contact seal; AH corresponds to set screw locking on the inner ring, and the final numeric suffix distinguishes the outer diameter or the width of the insert. Thus, SK100-206-KRR-AH11 is an insert for a 1-inch shaft, with KRR sealing and AH locking, in size 11 of the series.

These Y-bearings are used in belt conveyors, bucket elevators, mixers, mills, packaging belts and process equipment in food, chemical, cement and aggregate plants. In Argentina they are common in the oilseed, meat processing and waste treatment industries, where the environment has dust, humidity or frequent washdowns. The insert allows the bearing to be replaced without disassembling the housing, which reduces downtime on lines running continuously.

To select the insert, verify the shaft diameter and the locking type: the set screws of the AH series require a shaft with adequate hardness and finish so that it is not marked or does not spin. The KRR double-lip seal retains grease and blocks dust and water; in environments with pressure washing, additional seals or covers should be evaluated. Factory lubrication is lithium grease based, and relubrication should be done with the bearing rotating slowly and without overfilling. Housing alignment and uniform tightening of the screws prevent parasitic axial loads.

Regarding equivalences, insert bearings are interchanged between manufacturers by standardized shaft, outer diameter and width dimensions, but each brand defines its own suffixes for sealing and locking. It is not advisable to rely only on the code: the outer ring geometry, the locking type and the sealing must be compared. If the original equipment comes with an INA insert, substitution with another one of similar metric characteristics may be valid, but it is advisable to confirm the assembly with the housing before mounting.
