For rotating shafts that need reliable lubricant retention and contaminant exclusion, the DBH 5678 radial shaft seal is a direct-fit option. It suits gearboxes, pumps, electric motors and other industrial equipment where a compact sealing solution is required. The seal is identified by the code 5678 and features the Mz design, which includes a sealing lip and spring. MR Industrial Accessories supplies this brand and can help you confirm the right choice for your application.

The DBH 5678 is a radial shaft seal with a shaft diameter of 28.6 mm, a housing bore of 52.37 mm and a height of 11.11 mm. These dimensions correspond to the Mz design, a lip-and-spring configuration intended for rotating shafts where lubricant must be contained. The 5678 code makes it straightforward to locate in catalogs and ordering systems, which is useful for maintenance replacements.

Typical uses include gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. In each case, the seal keeps oil or grease in and keeps dust, water and particles out, protecting bearings and extending equipment life. The size makes it common in medium-sized machinery where radial space is limited but effective sealing is still needed. Machine tools and hydraulic systems with rotating shafts also use this type of seal.

Proper installation starts with checking that the shaft matches the specified diameter and has a smooth, burr-free surface. The housing bore must also be clean and within the specified dimension. Lubricate the lip before pressing the seal into place with a suitable tool, avoiding direct impacts. Orient the lip toward the fluid side. For high peripheral speeds, review the lip material recommendations before installation.
