The INA SK-KRR-AH series covers insert bearings (also called Y-bearings) that use a spherical outer ring and are locked onto the shaft with set screws. They sit in split plummer block housings or in any housing machined to accept the outer raceway, so the shaft turns while the housing stays put. This arrangement allows for minor misalignment and makes bearing changes straightforward.

Reading the code helps you order the right insert. Take SK100-206-KRR-AH11: SK marks the insert family with a spherical outer ring; 100-206 gives the nominal shaft size in inches plus the construction variant; KRR is the double-lip contact seal; AH tells you the inner ring is secured by set screws; and the final number (11) separates outer diameter or width versions within the series. So that reference is a 1-inch shaft insert with KRR sealing and AH locking.

You will find these bearings in belt conveyors, bucket elevators, mixers, mills, packaging lines and other process equipment across food, chemical, cement and aggregate operations. They suit plants where dust, moisture or regular washdowns are present. Because the insert can be swapped out without pulling the housing apart, maintenance crews can get a line back up without a full teardown.

For selection, confirm the shaft diameter and the locking method first. AH set screws need a shaft with the right hardness and surface finish so they bite without marking or slipping. The KRR double-lip seal keeps grease in and keeps dust and water out; if high-pressure washing is part of your routine, look at adding seals or covers. The bearing comes greased with lithium grease, and when regreasing, turn the shaft slowly and avoid overfilling. Align the housing and tighten screws evenly to prevent unwanted axial loads.

Interchange between brands is possible because shaft, outer diameter and width dimensions are standardized, but sealing and locking suffixes are brand-specific. Do not go by the code alone: compare outer ring geometry, locking style and seal arrangement. If the original equipment uses an INA insert, a similar metric replacement may work, but test-fit it in the housing before mounting.
