The SKF PER.UC AT-C Y-bearing is an insert with a spherical outer ring and set screw locking, designed to be mounted in split or pillow block housings. It is used in equipment with rotating shafts where misalignment needs to be compensated and lubricant kept inside. MR Accesorios Industriales supplies this line for plants and factories in Argentina.
The designation PER.UC AT-C is read in parts: PER indicates the series of inserts with spherical outer ring; UC corresponds to the set screw locking type on the inner ring; AT indicates sealing variants and -C identifies a specific execution within the category. The example PER.UC209AT-C shows the complete structure: series letters, a number defining the shaft diameter and suffixes distinguishing seals and tolerances. When ordering a replacement, it is best to provide the complete code to avoid confusion between versions.
These bearings are found in belt conveyors, mixers, screens, fans and transmission equipment in food, chemical and aggregate plants. In Argentina they are common in the oilseed, meatpacking and cement industries, where shafts experience moderate loads and some misalignment. They also appear in road and agricultural machinery working outdoors, since the sealing helps retain grease and slow the ingress of dust and water.
To choose correctly, look at the shaft diameter, the housing type and the working conditions. Set screw locking requires the shaft to have adequate hardness and finish; if the shaft is soft, it can be marked and loosen. Check the sealing: AT suffixes usually indicate labyrinths or seals that improve protection. During assembly, align the housing, lubricate as specified and tighten the screws with the proper wrench to avoid deforming the inner ring.
Y-bearings are interchangeable between brands if the main dimensions and locking type match. A UC insert from another brand can replace a PER.UC AT-C if the shaft diameter, width and screw thread are the same. However, seals and tolerances vary, so it is best to confirm equivalence with a specialist. At MR Accesorios Industriales we advise you to find the option that best suits your equipment.

Frequently Asked Questions
- What does the designation PER.UC AT-C mean?
- PER indicates an insert with spherical outer ring; UC, set screw locking; AT, sealing variant; and -C, a specific execution. The middle number defines the shaft diameter. It is an SKF code that should be copied in full when ordering a replacement.
- How is a Y-bearing with set screw locking mounted?
- The shaft is inserted into the inner ring, the housing is aligned and the set screws are tightened against the shaft. It is key that the shaft has the correct hardness and diameter, and that the proper wrench is used to avoid damaging the insert. Once locked, check that it turns freely.
- Can it be replaced by another brand?
- Yes, if shaft diameter, width, locking type and thread match. The main dimensions are usually standard, but seals and tolerances vary between manufacturers. Consult us with the original code and we will confirm the available equivalence.
