The DBH 1186 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. With dimensions of 31.70 mm shaft diameter, 58.40 mm housing diameter and 6.80 mm height, it is used in gearboxes, pumps, electric motors and industrial equipment where axial space is limited. Its A 306 design ensures effective sealing under continuous operating conditions.

The DBH 1186 is a radial shaft seal with a sealing lip. Its standard dimensions are 31.70 mm for shaft diameter (d), 58.40 mm for housing diameter (D) and 6.80 mm overall height (h). The A 306 design corresponds to a single lip configuration with spring, suitable for applications requiring low friction and good wear resistance. This seal is made from elastomers resistant to oils and greases, and its outer metal structure facilitates firm mounting in the housing.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In all these cases, the DBH 1186 seal protects bearings and gears against the ingress of dust, water or particles, and prevents lubricant leakage. It is a critical part in industrial maintenance, as its failure can cause unplanned downtime and costly damage to internal components.

To correctly select the seal, verify that the shaft and housing dimensions match those indicated. The shaft surface must have adequate hardness and roughness, and the housing must be clean and free of burrs. During assembly, lubricate the lip with the same oil or grease used in the application and use an installation tool that applies uniform pressure to avoid damaging the seal. If the shaft shows wear, evaluate the possibility of using a seal with an auxiliary lip or a wear sleeve.
