The SKF Y-bearing unit with insert bearing is a ready-to-mount shaft unit that combines a cast iron or sheet steel housing with an insert ball bearing. It is used to support rotating shafts in equipment where a compact, self-aligning and easy-to-install solution is required. MR Accesorios Industriales supplies this line for plants and workshops in Buenos Aires and throughout the country.
The designation of this line is read in blocks: the initial letter indicates the housing type, the numbers that follow define the size and design variant, and the suffixes provide information on sealing, locking or material. For example, F3BB 104-TF corresponds to a square four-bolt flange housing with an insert bearing of 1 inch bore and contact seal. The suffix -TF indicates a specific sealing that should be verified according to the working environment.
These housings appear in belt conveyors, bucket elevators, mixers, screens, fans and packaging lines. In Argentina they are found in food, cement, mining and paper plants, and in workshops that assemble or repair agricultural machinery. The combination of housing and insert bearing simplifies replacement: the complete unit is changed without regrinding the shaft or machining the housing.
To choose correctly, take into account the type of load, rotation speed and environment. If there is dust, water or frequent washdowns, prioritize a contact seal such as the one indicated by the suffix -TF. Verify that the shaft has the appropriate tolerance and that the mounting surface is clean and flat. Lubrication comes from the factory, but it is advisable to check the condition of the seal and the alignment before start-up.
Y-bearing units with insert bearing are available in different brands under equivalent nomenclatures. Interchangeability depends on the main dimensions, shaft diameter and locking type. It is not enough for the code to be similar: the center height, the distance between holes and the insert locking system must be compared. MR Accesorios Industriales can guide you to find the correct equivalent.
If you need to replace a unit, send via WhatsApp the complete code that appears on the housing or on the bearing plate. With that data, at MR Accesorios Industriales we identify the configuration and provide you with a quote. You can also send a photo of the part and the shaft dimensions to confirm the variant.

Frequently Asked Questions
- How do I identify the code of my Y-bearing unit?
- Look for the code engraved on the housing or on the insert bearing plate. Write down all the letters and numbers, including the suffixes. If it is not legible, send us a photo and the shaft dimensions via WhatsApp and we will help you identify it.
- What does the suffix -TF mean on an SKF housing?
- The suffix -TF indicates a contact seal variant, designed for environments with dust or moisture. Not all housings have it. To confirm whether your application needs this seal, consult us with the code and the working conditions.
- Can a Y-bearing unit from another brand be replaced by an SKF one?
- Yes, if the main dimensions match: shaft diameter, center height, distance between holes and locking type. Do not rely only on the code. Send us the dimensions or the original code and we will indicate the available equivalent.
