The DBH 5120Sil radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. Its dimensions of 39.42 mm shaft, 63.55 mm housing and 12.70 mm height make it suitable for assemblies where axial space is limited. The Lz design combines a sealing lip with a secondary exclusion lip, which improves performance in dusty or dirty environments. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal.

This item is a DBH radial shaft seal with the designation 5120Sil, with dimensions of 39.42 mm shaft diameter, 63.55 mm housing diameter and 12.70 mm height. The Lz design indicates a configuration with a main sealing lip and an auxiliary exclusion lip, intended to protect the sealing area from external particles. The lip elastomer runs on the rotating shaft, while the outer diameter is press-fitted into the housing. It is a common replacement part in equipment that requires oil or grease containment.

Typical applications for this seal include gearboxes, pumps, electric motors, drive shafts and process equipment. In all cases, the seal prevents lubricant leaks and the ingress of contaminants that accelerate wear on bearings and gears. Because of its Lz design, it is recommended in environments with dust, fine chips or moderate humidity, where the exclusion lip provides an additional barrier. It is also used in assemblies where the shaft has some eccentricity or slight misalignment.

To select this seal correctly, verify that the shaft, housing and height dimensions match those of the assembly. The shaft surface must be ground and have adequate hardness to prevent premature lip wear; low roughness and the absence of grooves or burrs are recommended. The housing must have an entry chamfer so the lip is not damaged during installation. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and install the seal with the lip facing the lubricant side. Avoid striking the elastomer and make sure it seats fully.
