The DBH 6918 oil seal is a single-lip radial seal that mounts on a 50.5 mm shaft and fits a 66 mm housing bore, with a height of 3.00/6.00 mm. Its A 337 design combines a sealing lip with an outer body that ensures tightness in rotating equipment. It is used to retain oil or grease and prevent the ingress of dust and contaminants in gearboxes, pumps and motors, among other industrial applications.

This item is a DBH radial shaft seal, identified by the designation 6918. Its dimensions are: shaft diameter (d) 50.5 mm, housing bore diameter (D) 66 mm and height (h) 3.00/6.00 mm. The A 337 design corresponds to a spring-loaded lip configuration that guarantees uniform contact on the shaft. DBH is a brand that MR carries, so the product meets its technical specifications.

Radial shaft seals such as the DBH 6918 are used on rotating shafts of gearboxes, centrifugal pumps, electric motors, mixers and transmission equipment. Their function is to retain lubricant inside the assembly and block the entry of external particles, extending the service life of bearings and gears. They are common in applications where axial space is limited and effective sealing is required at moderate speeds.

To correctly select this seal, verify that the shaft diameter and housing bore match the indicated dimensions. The shaft surface must be ground and free of burrs; the housing must be clean and undamaged. During installation, lubricate the lip and use an installation tool that prevents twisting. The 3.00/6.00 mm height allows some axial tolerance, but it is important to respect the housing depth for a firm seat.
