The DBH 5252Sil radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With dimensions of 20 mm shaft, 35 mm housing and 10 mm height, and Lx design, it is a common replacement part in pumps, electric motors, gearboxes and transmission equipment. MR Accesorios Industriales sells it as part of its line of seals and oil seals for industrial maintenance.

This item is a DBH 5252Sil radial shaft seal, identified by its 5252Sil designation. Its dimensions are 20 mm shaft diameter (d), 35 mm housing diameter (D) and 10 mm height (h). The Lx design corresponds to a single-lip configuration with a spring, suitable for rotating lubricated shafts. The lip elastomer and the outer metal reinforcement work together to maintain dynamic contact and absorb small misalignments. It is a sealing component intended for direct replacement, not for machining or on-site adaptation.

Typical applications for a seal of these dimensions include small centrifugal pumps, low-power electric motors, gearboxes, compressors, mixers and belt or chain transmission equipment. In all cases it serves to retain the oil or grease inside the assembly and prevent contaminants from entering from outside. It is also used on fan shafts, conveyors and machine tools where mounting space is limited and a reliable seal at moderate speeds is required.

To correctly select this seal, check that the shaft diameter is 20 mm and the housing is 35 mm, with a minimum depth of 10 mm. The shaft surface must be ground and free of burrs; excessive roughness accelerates lip wear. Before installing, lubricate the lip with the same oil used in the equipment and check that the spring is in position. The Lx design tolerates slight eccentricity, but it is advisable to align the shaft with the housing to extend the service life of the seal.
