The DBH 5912 oil seal is a radial shaft seal with a 120 mm shaft diameter, 147.50 mm housing diameter and 14 mm height, in Lz design. It is used to retain lubricant and exclude contaminants in rotating equipment, where the shaft turns inside a fixed housing. It is a wear part that should be replaced when oil leakage or dust ingress appears. MR Accesorios Industriales supplies it and advises you on choosing the correct replacement.

This item is a DBH 5912 radial shaft seal, identified by its designation 5912. Its dimensions are 120 mm shaft diameter (d), 147.50 mm housing diameter (D) and 14.00 mm height (h). The Lz design defines the geometry of the lip and the body, intended to be press-fitted into the housing and seal against the shaft. It is a precision component: any variation in these dimensions affects the fit and the sealing performance.

Radial shaft seals of this size appear in gearboxes, pumps, reducers, rollers and transmission equipment. Their function is twofold: to retain the oil or grease inside the assembly and to prevent water, dust or particles from entering. In industrial plants, a worn oil seal is detected by lubricant stains, high consumption or noise in the nearby bearing. Replacing it in time prevents major damage to the shaft and the bearings.

To select the replacement, verify that the shaft diameter, housing diameter and height match those of the original oil seal. Also check the condition of the shaft surface: a scratched or worn track means the lip will not seal even if the dimensions are correct. The Lz design orients the lip in a specific way; if the installation is reversed, sealing may fail. Lubricate the lip before assembly and avoid striking it during installation.
