The DBH 9840 is a labyrinth-type radial seal from our seals and oil seals line. It fits a 100 mm shaft and a 128 mm housing, with a height range of 15.00/25.00 mm that accommodates different installation depths. Its A 088 design uses a specific labyrinth path to help retain lubricant and keep contaminants out of rotating equipment.

This seal is identified by the code 9840. Key dimensions are shaft 100 mm, housing 128 mm, and height 15.00/25.00 mm. The A 088 designation refers to the labyrinth configuration. Because it is a precision component, selection should be based on the actual operating conditions of the equipment.

Typical uses include gearboxes, pumps, electric motors, reducers, and other power transmission equipment. In areas exposed to dust, water, or chips, the seal helps prevent lubricant loss and the ingress of particles, which supports the service life of bearings and shafts. It is often found in food, mining, cement, and process industry applications where reliability and predictive maintenance matter.

Proper installation starts with clean shaft and housing surfaces, free of burrs or scratches, and tolerances that suit radial seals. Lubricate the lip before fitting, and use an installation tool that applies even pressure to avoid damage. When choosing a seal, consider rotation speed, operating temperature, and the fluid being retained. Our technical team can help you evaluate these factors.
