This item is a DBH 5031Sil radial shaft seal, identified by its designation 5031Sil. Its dimensions are 28.00 mm shaft diameter, 40.00 mm housing diameter and 7.00 mm height. The Lx design corresponds to a configuration with a sealing lip and spring, suitable for rotating shafts with lubrication. The elastomer and the reinforcing metal ensure sealing and wear resistance under continuous operating conditions.

Radial shaft seals such as the DBH 5031Sil are used in gearboxes, centrifugal pumps, electric motors, compressors, transmission shafts and process equipment. Their function is to retain the oil or grease inside the assembly and block dust, water or particles that could damage the bearings. They are also used in applications where there is a pressure difference between the inside and outside of the equipment.

To mount this seal, verify that the shaft measures 28 mm and the housing 40 mm, with a width of 7 mm. The shaft surface must be ground and free of burrs; the housing, clean and free of deformation. Lubricate the lip before inserting it and use a mounting tool that presses on the outer diameter, never on the lip. If the equipment operates at high speed or temperature, ask about material variants.
