The DBH 1042 oil seal is a single-lip radial shaft seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions —42.86 mm shaft diameter, 65.25 mm housing diameter and a height of 9.50/11.91 mm— make it suitable for equipment with limited mounting space. DBH is a brand that MR carries, and this particular model corresponds to designation 1042, with an A 187 BID design that combines a sealing lip and an outer body for press-fit installation.

This DBH 1042 oil seal is identified by its designation 1042 and belongs to the category of seals and radial shaft seals. Its main dimensions are: shaft diameter (d) of 42.86 mm, housing diameter (D) of 65.25 mm and height (h) of 9.50/11.91 mm. The A 187 BID design indicates a specific construction within the DBH line, with a sealing lip that runs on the shaft and an outer diameter that is press-fitted into the housing. The dual height (9.50/11.91 mm) suggests that the seal may have a stepped section or a particular geometry that must be respected during installation.

Radial shaft seals such as the DBH 1042 are used in gearboxes, pumps, electric motors, transmission shafts and industrial equipment in general. Their function is twofold: on one hand, they retain the oil or grease inside the assembly, preventing leaks; on the other, they prevent the ingress of dust, water or particles that could damage bearings or gears. They are critical components in applications where the shaft rotates continuously and where sealing reliability directly affects equipment service life.

To correctly select a seal such as the DBH 1042, it is essential to verify that the shaft and housing dimensions match those of the equipment. The height must also be compatible with the housing depth. During installation, it is recommended to clean the surfaces, lubricate the lip with the same oil used in the system and use an installation tool that prevents damage to the lip. Shaft runout and surface finish are factors that influence seal performance. If the original seal is not available, an equivalent with the same dimensions and design characteristics can be sourced.
