The DBH 9090 oil seal is a single-lip radial seal that mounts on the shaft and seals against the housing to retain lubricant and stop the entry of dust, water or particles. With a 16 mm shaft diameter, 40 mm housing and 8 mm height, it is a compact size widely used in power transmission equipment, pumps and electric motors. Its Lx design corresponds to a rubber lip with spring, without an external dust lip.

This oil seal is identified by its designation 9090 and by the dimensions listed on the product page: shaft diameter 16 mm, housing diameter 40 mm and height 8.00 mm. The Lx design indicates an elastomer sealing lip with a steel spring, without a secondary exclusion lip. That configuration is the most common for retaining oil or grease in bearing chambers and gearboxes where there is no direct exposure to mud or pressurized water.

Typical applications for a seal of this size include small electric motors, centrifugal pumps, speed reducers, compressors and power transmission equipment. It is also found in machine tools, conveyor belts and process equipment where the lubricant must be contained inside the assembly and prevented from escaping along the shaft. In every case it is advisable to verify that the shaft and housing are in good condition before installing it.

To select the correct seal, take into account the shaft diameter, the housing diameter and the available height. The Lx design works well with shafts rotating at moderate speeds and with general-purpose lubricants. If the equipment operates with a lot of dirt or water, a seal with an additional exclusion lip may be better suited. The shaft surface must be polished and free of burrs, and the housing must have its entry chamfer in good condition so the lip is not damaged during installation.
