The SKF SYK FM Y-housing is an assembly made up of a cast iron housing and an insert bearing with set screw fixing. It is used to support rotating shafts in equipment where alignment is not perfect and simple, compact mounting is required. It is a common solution in agricultural machinery, conveyors and process equipment, and allows the bearing to self-align within the housing. MR Accesorios Industriales distributes this line as an official brand.
The SYK FM designation identifies a SYK series Y-housing with insert bearing and set screw fixing. In the code SYK 40 FM, the central digits indicate the shaft diameter for which the insert is intended, and the suffix FM indicates the type of fixing and the bearing sealing. To choose the correct code, take into account the shaft diameter and the type of load, and consult the series table to confirm the exact combination.
These housings are used in belt conveyors, bucket elevators, agricultural machinery, grinding and mixing equipment, and ventilation systems. In Argentina they are common in grain plants, meat processing plants, quarries and industrial facilities that need easily replaceable spare parts. Their design allows the shaft to be mounted without machining the housing and absorbs small misalignments, which simplifies field maintenance.
To select the housing, verify the shaft diameter, the type of load and the environmental conditions. The insert sealing must be compatible with dust, humidity or frequent washdowns. During mounting, ensure that the housing rests on a flat surface and that the set screws are tightened onto the shaft without damaging it. Insert lubrication is permanent in most cases, but clearance and alignment should be checked after the first hours of operation.
Y-housings with insert bearing are interchangeable between brands if the main dimensions match: shaft diameter, fixing hole spacing, center height and fixing type. It is not enough for the code to be similar; the drawing dimensions must be compared. At MR Accesorios Industriales we can guide you on equivalence with other brands, always starting from the original code and the actual measurements of the equipment.
If you need to replace an SKF SYK FM Y-housing, send us by WhatsApp the complete code that appears on the equipment or on the bearing plate. With that data and a photo of the mounting, we will send you the quote. We handle technical inquiries from distributors, factories and industrial plants nationwide.

Frequently Asked Questions
- What does the FM suffix mean in a SYK housing?
- The FM suffix indicates the type of fixing and the sealing of the insert bearing. In the SYK series, the combination of letters and numbers defines the shaft diameter and the insert characteristics. To confirm the exact meaning, compare the complete code with the series table or ask us on WhatsApp.
- How do I know if a SYK housing is compatible with my machine?
- You have to compare the shaft diameter, the fixing hole spacing, the center height of the shaft and the insert fixing type. If those measurements match, the housing is interchangeable. Do not rely only on the code; verify the dimensions on the drawing or on the original part.
- What lubrication does a housing with insert bearing need?
- Most insert bearings come lubricated for life and do not require periodic maintenance. In environments with a lot of dirt or humidity, it is advisable to check the sealing condition and, if the insert has a grease fitting, add compatible grease according to the type of work. Ask us if you have doubts about the application.
