The SKF PER.HYY Y-bearing insert is a bearing unit with an extended inner ring and set screw locking system, designed to be mounted directly on shafts without the need for complex machining. It is used in applications requiring a compact and easy-to-install solution, such as conveyors, agricultural machinery and industrial equipment in general. Its sealed design allows operation in environments with dust or moderate humidity, extending the bearing's service life.
The designation PER.HYY identifies SKF Y-bearing inserts with extended inner ring and set screw locking. The prefix PER indicates the series, while HYY indicates specific sealing and design characteristics. For example, the code PER.204HYY2 corresponds to a bearing with a 20 mm bore, thanks to the suffix 204. This nomenclature allows quick identification of the size and sealing variants, making it easier to select the right replacement.
These bearings are used in a wide variety of industrial applications in Argentina, such as belt conveyors, bucket elevators, agricultural machines, packaging equipment and transmission systems in food and textile plants. Their ability to withstand moderate radial and axial loads makes them ideal for equipment requiring robustness and low maintenance. MR Accesorios Industriales supplies this line to serve the domestic industry.
To correctly select a Y-bearing insert, it is essential to consider the shaft diameter, the type of load and the environmental conditions. The HYY seal provides protection against contaminants, but in very aggressive environments additional seals should be evaluated. Mounting must be done with the set screws properly tightened on the shaft, verifying alignment to avoid parasitic stresses. Lifetime lubrication simplifies maintenance, although in severe applications periodic relubrication may be required.
Regarding equivalences, SKF Y-bearing inserts can be interchanged with those of other brands that follow the same dimensional nomenclature, such as series 204, 205, etc. However, it is important to verify tolerances and the locking type, as they may vary between manufacturers. To ensure compatibility, it is always advisable to consult a specialist and provide the complete code of the original bearing.
