The SKF SY..LF series Y-bearing housing with insert bearing is a compact assembly that combines a cast iron housing unit with a self-aligning, sealed insert bearing. It is used to mount rotating shafts on fixed structures, providing radial support and allowing minor misalignments. It is a practical solution for belt, chain or coupling drives in industrial equipment. MR Accesorios Industriales sells this line as an official brand for the Argentine market.

The SY..LF designation is read as follows: SY indicates a Y-type housing, the number that follows is the shaft diameter in millimeters (for example, SY 25 LF for a 25 mm shaft) and LF indicates a specific sealing and lubrication variant. Examples in the series are SY 25 LF, SY 30 LF, SY 35 LF, SY 40 LF and SY 55 LF. Each size has standardized dimensions, but to confirm the exact dimensions of your application it is advisable to consult the corresponding data sheet.

These housings are used in a wide variety of industries in Argentina: food, textile, material handling, agricultural machinery, packaging equipment and ventilation systems. They are common in belt conveyors, bucket elevators, mixers, centrifugal pumps and drive shafts. Their design allows them to be easily mounted on metal or concrete structures, and the insert bearing is fixed to the shaft by means of set screws or adapter sleeve, depending on the model.

To select the right housing, take into account the radial and axial load that the shaft will support, the rotation speed and the environmental conditions. The LF seal protects against dust and moisture, but if there is exposure to liquids or fine particles, consider additional seals. The internal clearance of the insert bearing allows some misalignment, but it is important to align the housings well to avoid parasitic loads. Lifetime lubrication is common in these inserts; if they are relubricable, follow the maintenance plan.

As for equivalents, other manufacturers offer Y-bearing housings with insert bearings of similar dimensions, but there is no universal interchangeability: always check shaft diameter, hole spacing, center height and type of locking. SKF is a global reference and its dimensions usually match international standards, which facilitates replacement. If you need to replace an existing housing, the safest approach is to compare the critical dimensions or consult with our technical team.
