The DBH 5223 is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a fixed housing. It measures 45 mm at the shaft, 65 mm at the housing bore, and 10 mm in height, which places it in gearboxes, pumps, electric motors, and other power transmission equipment. MR Industrial Accessories LLC supplies this brand and helps you confirm the right seal for the job.

In the DBH line, 5223 identifies both the size and the construction. This seal uses the Lz design: a single sealing lip with a spring, held in a metal case that presses into the housing. The lip rides on the shaft and works with permanent lubrication. Those three figures — shaft 45.00 mm, housing 65.00 mm, height 10.00 mm — are what you match against the equipment before ordering.

Typical service includes gearboxes and reducers, centrifugal pumps, electric motors, conveyor rollers, and machine tools, as well as agricultural and industrial machinery exposed to dust or moisture. Any application with a 45 mm shaft and a 65 mm bore is a starting candidate for the 5223, but the condition of the shaft surface and the operating temperature still need to be checked.

Installation calls for a clean bore with no deformation and a shaft free of burrs or scoring. Seat the seal with a press or a support tube sized to the outer case; never drive it in by hitting the lip. Lubricate the lip with the same oil or grease used in the equipment before fitting. If the shaft shows a deep groove, an offset-lip seal or a wear sleeve may be the better route.

Seal selection depends on speed, temperature, and the fluid being sealed. Send the full part number along with the shaft, housing, and height dimensions, and we can also cross-reference equivalents in other brands or seal lines that keep the same Lz design. Details such as equipment type, rotation speed, temperature, and lubricant make the match more precise.
