The Y-bearing housing with SKF insert is an assembled unit that combines a cast iron housing with an insert ball bearing, ready to mount on rotating shafts. It is used to support and align shafts in transmission, transport, and industrial process equipment. MR Accesorios Industriales markets this line in Buenos Aires, Argentina, with technical advice to choose the correct code for your application.
The designation of this line is read in blocks: the series P2B identifies the two-bolt split housing, and the number that follows —as in P2B 111-SRB-SRE or P2B 207-SRB-SRE— indicates the size of the insert bearing it houses. The suffixes SRB and SRE correspond to sealing and insert configuration variants. In the examples P2B 215-SRB-SRE, P2B 307-SRB-SRE and P2B 315-SRB-SRE you can see how the size changes while maintaining the same housing format.
These housings are applied in belt conveyors, bucket elevators, mixers, fans, pumps, and agricultural machinery. In Argentina they are common in food plants, cement plants, quarries, and agro-industrial establishments, where the environment often has dust, moisture, or frequent washdowns. The cast iron housing and sealed insert allow supporting the shaft with proper alignment and facilitate bearing replacement without disassembling the entire assembly.
To select the housing, check the shaft diameter and working conditions: load, speed, and type of contaminant. The SRB or SRE sealing defines protection against dust and water; choose the variant according to the environment. During mounting, ensure that the base is flat and aligned, and that the bolts are tightened evenly. Lubrication of the insert should follow the manufacturer's recommendation, and it is advisable to check the clearance and fixation of the inner ring on the shaft.
Y-bearing housings with insert bearings from different brands are usually interchangeable if the main dimensions match: shaft diameter, distance between holes, and height to center. However, sealing suffixes and tolerances may vary between manufacturers. Therefore, when comparing codes, do not rely only on the number: check the dimensional data. At MR Accesorios Industriales we can guide you on compatibilities without compromising equipment performance.
If you already have the code of the housing you need, send it via WhatsApp to MR Accesorios Industriales and we will provide the quote. If you are not sure of the designation, send us a photo of the part or the shaft dimensions and the distance between holes: with that data we help you identify the correct reference within the SKF line.

Frequently Asked Questions
- What does the P2B designation mean in an SKF housing?
- The P2B series corresponds to a two-bolt split housing. The number that follows indicates the size of the insert bearing, and the suffixes SRB or SRE define sealing variants. For example, P2B 207-SRB-SRE houses a size 207 insert with SRB/SRE sealing.
- How do I choose between a housing with SRB sealing and one with SRE?
- The choice depends on the environment: if there is abundant dust or frequent washdowns, a variant with greater protection is advisable. The suffix SRB or SRE indicates the type of insert sealing. To define the best option for you, we need to know the working conditions of your equipment.
- Are SKF housings interchangeable with those of other brands?
- They can be interchangeable if the main dimensions match: shaft diameter, distance between holes, and height to center. Still, sealing suffixes and tolerances vary between manufacturers. Before replacing, check the dimensional data or consult us with the code and dimensions.
