A radial shaft seal is a small component with a large job: it keeps lubricant inside the housing and keeps dust, water and other contaminants out. The DBH 5916 belongs to this family. It is a single-lip seal with an Lz lip design, sized for a shaft of 123.83 mm, a housing bore of 155.60 mm and a width of 14.28 mm. Those dimensions point to larger rotating equipment such as gearboxes, pumps and industrial drives. MR Industrial Accessories supplies this brand and can help you confirm that a seal matches your application before you order.

The code 5916 identifies the size, while DBH refers to the seal type. Reading the three measurements in order makes selection straightforward: shaft 123.83 mm, housing 155.60 mm, width 14.28 mm. The Lz lip design uses a spring to hold the sealing lip against the shaft, so contact stays consistent as the shaft turns. The lip is made from an elastomer that resists oils and greases, and the outer metal case provides the rigidity needed for a press fit into the housing bore.

Seals of this size are found in gearboxes, centrifugal pumps, mills, mixers and power transmission equipment. In every case the task is the same: separate the lubricated interior from the outside environment. Because the dimensions suit larger shafts, these seals are common in medium and heavy equipment running at moderate speeds, where a stable barrier matters for long service intervals. Maintenance teams also keep them on hand as spares for scheduled rebuilds.

Installation decides how well the seal performs. Check that the shaft and bore are clean and free of burrs or scratches. Apply a little of the same oil or grease used in the equipment to the lip, then press the seal in with a proper tool, keeping force on the metal case and never on the lip. The 14.28 mm width should sit flush or slightly recessed, depending on how the housing is machined. If the shaft is worn, a repair sleeve or a different size may be the better route.
