The DBH 5558 is a radial shaft seal that fits into a housing and creates a dynamic seal against a rotating shaft. It keeps lubricant in and keeps dust, water and other particles out. With a shaft size of 44.45 mm, a housing bore of 85.63 mm and a width of 15.87 mm, it suits assemblies where axial space is tight but reliable sealing is still required. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

This seal carries the DBH designation and the code 5558. The Lx configuration indicates a single lip with a spring, designed for rotating shaft applications. The lip presses against the shaft to form the dynamic seal, while the metal outer case holds the seal in the housing. The elastomer is selected to handle continuous contact with oil or grease and the temperatures typically found in industrial machinery.

You will find seals of this size in gearboxes, pumps, electric motors, mixers and conveyors, as well as in process equipment where bearings and gears need protection from outside contamination. Because it is a wear part, inspect the seal area whenever you notice lubricant leaks, unusual noise or vibration. In dirty or wet environments, the seal often works together with other sealing components to keep the internal assembly clean.

Before installing a replacement, check the shaft for burrs, scratches or wear on the contact track. Clean and lubricate the surface, and make sure the housing is in good condition and not deformed. Use a tube or socket of the correct diameter to press the seal in evenly, and never strike the lip directly. If the shaft has a deep groove, you may need to replace the shaft or choose a size that shifts the contact track. Proper alignment between shaft and housing is essential for seal life.

If you need an equivalent to the 5558, send us the code and the current dimensions. A photo of the old seal or the housing also helps. With that information we can point you to a compatible option within the DBH line or from other brands we carry. MR Industrial Accessories handles technical inquiries and helps you avoid buying a seal that does not match your application.
