The SKF Y-bearing housing with insert bearing is an assembled unit that combines a housing unit with a Y-series insert bearing. It is used to mount rotating shafts on fixed structures, with alignment and lubrication already handled at the factory. It is a common solution in power transmission and conveying equipment that needs simple, compact and quick-to-mount support. MR Accesorios Industriales supplies this line for industrial applications in Buenos Aires, Argentina.
The PDNB designation identifies this category of Y-bearing housings with insert bearing. The numbers that appear below, as in PDNB 206, PDNB 207 or PDNB 308, correspond to the size of the insert bearing that the housing holds. They are not dimensions of the housing itself, but a reference that allows the unit to be matched with the corresponding shaft diameter. To choose the correct part number, have on hand the shaft diameter and the type of fixing your machine needs.
These housings are used in a wide variety of industries in Argentina. They appear in belt conveyors, bucket elevators, mixers, fans, centrifugal pumps and process equipment in food, chemical and aggregate processing plants. They are also common in the agro-industrial sector, in milling machines and in irrigation systems. Their compact format and the possibility of mounting them on metal structures make them practical for replacing worn supports or for new equipment.
To select the right Y-bearing housing, check that the shaft diameter matches the insert bearing part number. Check the sealing type: there are versions with simple seals or with additional protections for dusty or humid environments. Mounting requires a flat, clean surface and careful alignment to avoid parasitic axial loads. Lubrication comes from the factory, but the manufacturer's instructions for relubrication should be followed according to operating conditions.
Regarding equivalences, Y-bearing housings with insert bearing from different brands usually share standardized dimensions, which allows units to be interchanged between manufacturers if the shaft diameter and the type of fixing match. However, not all seals or load capacities are identical. Therefore, before replacing a unit, it is advisable to verify the complete part number and the service conditions. MR Accesorios Industriales can advise you to find the right alternative.
If you already have the PDNB part number you need, send it by WhatsApp to MR Accesorios Industriales and we will send you the quote. If you are not sure which one is correct, tell us the shaft diameter, the type of mounting and the operating conditions, and we will help you identify it. With more than 80 years in the market, at MR we know Y-bearing housings and their applications in Argentine industry.

Frequently Asked Questions
- How do I choose the correct PDNB part number for my shaft?
- The PDNB part number relates to the size of the insert bearing, which in turn defines the shaft diameter. Measure the shaft diameter where the housing is mounted and send us that data along with the part number on the old part. That way we can confirm the exact reference.
- Can SKF Y-bearing housings be relubricated?
- Many models of Y-bearing housings with insert bearing allow relubrication through a channel in the outer ring. Check whether your unit has the grease hole. If it does not, the bearing comes lubricated for life and requires no additional maintenance.
- What is the difference between a Y-bearing housing and a split plummer block housing?
- The Y-bearing housing with insert bearing is a compact unit that holds a Y-series insert bearing. The split plummer block housing, on the other hand, is a split housing that is mounted on a conventional ball or roller bearing. The choice depends on the type of shaft and the mounting conditions.
