The DBH 5670 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a housing. Its Mx design is a single-lip, spring-loaded configuration for general sealing duty. The seal is press-fitted into the housing and runs against the shaft, making it a common wear part in gearboxes, pumps, motors and transmission equipment.

The code 5670 identifies this seal within the DBH line. Its three critical dimensions are shaft 19 mm, housing 31.75 mm and width 7.90 mm. The Mx designation covers a standard single lip with an internal spring, a setup suited to everyday oil and grease sealing. The elastomer body and spring work together to hold the lip against the shaft and resist the wear that comes with continuous operation.

You will find this type of seal in gearboxes, centrifugal pumps, electric motors, compressors, mixers and belt or chain drives. It also appears in agricultural machinery, conveyors and production lines, where dust or moisture would otherwise reach the bearings. In every case, the seal's job is the same: retain lubricant and block outside contamination.

Installation calls for a clean shaft and housing, free of burrs. Coat the lip with the same oil or grease used in the equipment. Press the seal in squarely with a tube that contacts the outer diameter, never the lip. The 7.90 mm width should end up flush or slightly recessed. If the shaft surface is worn, an auxiliary lip may be worth considering.
