Description
SKF PER.308RRRB50 is a y-bearing (insert bearing) reference, within Bearings. Request a quote for PER.308RRRB50 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF PER.RRRB Y-bearing is an insert bearing with a spherical outer ring and set screw locking system, designed to be mounted in split plummer block or flanged housings. It is used in equipment where the shaft rotates at moderate speeds and loads are not high, such as conveyor belts, fans or agricultural machinery. Its design allows initial alignment and quick locking to the shaft. At MR Accesorios Industriales we supply this line so you can equip your machines with reliable components.
The SKF PER.RRRB designation identifies an insert bearing of the Y series with a spherical outer ring and locking by means of set screws. In the code, the letters PER indicate the type of insert, while RRRB indicates construction characteristics such as sealing and the locking system. For example, model PER.308RRRB50 corresponds to a bearing with a bore diameter of 50 mm, although each specific size is confirmed in the registry. Knowing this nomenclature allows you to quickly identify the spare part you need.
These bearings are used in a wide variety of industrial applications in Argentina. They are common in belt conveyors, bucket elevators, mixers, fans and equipment for the food, cement and agricultural industries. Their ability to withstand radial loads and a certain misalignment makes them suitable for shafts that do not require extreme precision. They are also found in textile machines and in power transmission systems in aggregate processing plants.
To select the right Y-bearing, take into account the shaft diameter, the type of load and the environmental conditions. Verify that the housing is compatible with the spherical outer ring and that the set screw locking system is appropriate for your application. During mounting, make sure the shaft is clean and free of burrs, and apply the recommended torque to the screws. Proper lubrication and correct alignment extend the service life of the bearing.
As for equivalents, SKF Y-bearings can be interchanged with those of other brands that follow the same dimension standard. However, it is important to verify the tolerances and the type of sealing, since they may vary between manufacturers. Always consult a specialist before replacing one bearing with another of a different brand to ensure compatibility. At MR Accesorios Industriales we can help you find the best option for your equipment.

Frequently Asked Questions
- What does the designation PER.RRRB mean in SKF bearings?
- PER.RRRB is the nomenclature that SKF uses to identify insert bearings of the Y series with a spherical outer ring and set screw locking. The letters PER indicate the type of insert and RRRB the sealing and locking characteristics. Each code also includes the bore diameter, as in PER.308RRRB50.
- In what applications is this bearing recommended?
- It is used in equipment with rotating shafts at moderate speed and radial loads, such as conveyors, fans, mixers and agricultural machinery. Its design allows mounting in split plummer block or flanged housings and tolerates small misalignments, so it is common in demanding industrial environments.
- How should I mount a Y-bearing to ensure its operation?
- Clean the shaft and verify that it has no burrs. Place the bearing in the housing and tighten the set screws with the recommended torque. Make sure the lubrication is adequate and the alignment is correct to avoid additional loads that reduce the service life of the bearing.
