The SKF Y-bearing (insert bearing) of the YAR RF series is a single row bearing with an extended inner ring and seals, designed to be mounted in split plummer block housings or tensioners. It is used in equipment where the shaft rotates and a compact unit is needed that resists contamination and lubricant leaks. Its construction allows the bearing to be aligned and locked to the shaft by means of set screws, which simplifies mounting and maintenance in belt, chain or roller drives.

The YAR RF series designation reads as follows: YAR identifies the category of Y-bearings with extended inner ring; RF indicates that the bearing is sealed on both sides (contact seal). Examples such as YAR 204-2RF, YAR 205-2RF or YAR 207-2RF show the size number (204, 205, 206, 207, 208) and the suffix -2RF that confirms the double seal. In some cases an additional code appears, such as YAR 204-012-2RF, which specifies a bore diameter or locking variant; it is always advisable to verify the complete part number before ordering.

These bearings are used in transmission and conveying equipment: conveyor belts, bucket elevators, mixers, mills, screens, fans and machinery for food and beverages. In Argentina they are common in grain plants, meat processing plants, tanneries and plastics factories, where the environment has dust, humidity or frequent washdowns. They are also found in seeders and harvesters, in wheel axle supports and in cleaning systems. Their sealed design makes them suitable for places where frequent lubrication is not possible.

To select the YAR RF bearing, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The RF seal protects against dust and splashes, but if there is immersion or pressure washing, additional seals or labyrinth housings should be evaluated. Mounting is done on the shaft with set screws on the extended inner ring; it is key to adjust the axial and radial clearance according to the equipment, align the housing and lubricate with the grease recommended by the manufacturer. Poor alignment accelerates seal wear.

As for equivalents, SKF YAR RF series Y-bearings can be interchanged with other brands that offer inserts of similar dimensions, such as the YAR, YET, YEL or UC series, as long as the bore diameter, width and locking type match. Not all brands use the same nomenclature, so interchangeability is confirmed by comparing drawings or equivalent part numbers.
