The SKF Y-bearing insert of the PER.UC-A series is a bearing with an extended inner ring and a set screw locking system, designed to be mounted directly on shafts and housed in split or solid pillow blocks. It is used in equipment that requires a simple bearing unit, quick to mount and easy to replace, such as conveyors, fans, mixers and agricultural machinery. MR Accesorios Industriales supplies this line with technical advice to choose the right configuration.
The designation of the PER.UC-A series reads as follows: PER indicates that it is a Y-bearing insert, UC corresponds to the series with extended inner ring and set screw locking, and the suffix -A indicates a design variant within the series. The numbers that follow, as in PER.UC202-10-A or PER.UC218-A, identify the size and the bore dimension; in some cases they include an additional numeric suffix that distinguishes fractional or inch diameters. To know the exact dimensions of each item, check the product page or send us the complete part number.
This type of bearing is used in a wide variety of industrial applications in Argentina. It is commonly found in belt conveyors, bucket elevators, mixers, agitators, fans, pumps, equipment for the food industry, agricultural machinery and transmission systems in manufacturing plants. Its design allows it to be mounted on shafts with normal tolerances and housed in split pillow blocks, which simplifies maintenance and reduces downtime. It is also used in equipment with combined loads and moderate speeds.
To correctly select a Y-bearing insert of this series, take into account the shaft diameter, the type of load, the rotation speed and the environmental conditions. Sealing is key: there are versions with single or double lip seals, and with or without additional protection against dust and water. Lubrication can be with lithium or synthetic grease, depending on temperature and speed. During mounting, make sure the shaft is clean and free of burrs, and tighten the set screws with the appropriate wrench. Alignment between housings prevents unnecessary stress and extends service life.
Regarding equivalences and interchangeability, Y-bearing inserts of the UC series are dimensionally interchangeable between different manufacturers that follow the same standards. This means that an SKF bearing can be replaced by another equivalent brand as long as the bore dimensions, width and locking type match. However, always verify tolerances and sealing, because they can vary between brands. MR Accesorios Industriales supplies SKF and can advise you on the best option for your equipment.
