The SKF SY..LF Y-bearing unit is a ready-to-mount assembly that pairs a cast iron housing with a sealed, self-aligning insert bearing. It supports rotating shafts on fixed structures, handles radial loads, and tolerates slight misalignment. Belt, chain, and coupling drives in industrial equipment commonly use this type of unit. MR Industrial Accessories supplies this line to customers across the United States and Latin America.
The code breaks down into three parts. SY tells you it is a Y-bearing unit. The number is the shaft diameter in millimeters, so SY 25 LF fits a 25 mm shaft. LF refers to a particular sealing and lubrication version. Common sizes include SY 25 LF, SY 30 LF, SY 35 LF, SY 40 LF, and SY 55 LF. For exact dimensions of a given size, check the technical data sheet.
These units appear in food processing, textiles, material handling, agricultural equipment, packaging lines, and ventilation systems. You will find them on belt conveyors, bucket elevators, mixers, centrifugal pumps, and drive shafts. Mounting on steel or concrete is straightforward. Depending on the model, the insert bearing locks to the shaft with set screws or an adapter sleeve.
When selecting a unit, look at the radial and axial loads the shaft will carry, the rotation speed, and the operating environment. The LF seal keeps out dust and moisture. If liquids or fine particles are present, consider adding extra sealing. The insert bearing's internal clearance absorbs some misalignment, but proper alignment of the units helps avoid parasitic loads. Many inserts are lubricated for life; if yours can be relubricated, follow the maintenance schedule.
Other manufacturers make Y-bearing units with insert bearings that have similar dimensions, but interchangeability is not universal. Always confirm shaft diameter, hole spacing, center height, and fixing method. SKF dimensions typically follow international standards, which simplifies replacement. For a reliable swap, compare the critical dimensions or ask our technical team.
