The DBH 5400 is a radial shaft seal designed to keep lubricant in and contaminants out where a shaft meets a housing. It is press-fitted into the bore and runs against the shaft, with a flexible lip that accommodates minor misalignment and vibration. This seal is suited for rotating equipment in industrial settings.

This DBH oil seal carries the designation 5400. Shaft diameter is 19 mm, housing bore is 41.24 mm, and seal width is 6.35 mm. The Lx design indicates a single lip with a metal case, suitable for grease or oil lubrication in light to medium duty equipment.

Common uses include small gearboxes, electric motors, centrifugal pumps, fans, screw compressors, and transmission assemblies. It also fits machine tools, conveyors, and process equipment where a 19 mm shaft requires lubricant retention. Before replacing, inspect the shaft and housing for wear or damage.

For installation, clean the housing and shaft, remove any burrs, and lubricate the lip. Press the seal in squarely without hammering on the case. Consider shaft speed, operating temperature, and lubricant type when selecting. If the shaft is worn, a seal with an auxiliary lip may help.
