The DBH 5677 is a radial shaft seal from the DBH line, sized for a 34.93 mm shaft, a 46.43 mm housing bore and a 9.52 mm overall height. Its Lz configuration uses a sealing lip with a spring to keep contact on the rotating shaft. MR Industrial Accessories LLC supplies this brand for sealing points where lubricant retention and contaminant exclusion matter.

Reading the code helps you confirm the fit: 5677 identifies the size in the DBH range, while the three figures cover shaft 34.93 mm, housing 46.43 mm and width 9.52 mm. The Lz designation points to a lip-and-spring build. Before pulling a seal from a housing, compare these values against the shaft and bore, because a mismatch will cause leaks or poor seating.

Typical service includes gearboxes, pumps, electric motors, transmission shafts and process equipment that runs continuously. You will also find this size in automotive assemblies, farm machinery and hydraulic systems where the shaft turns at moderate speed and lubricant is present. In each case the seal acts as the dynamic barrier that keeps oil or grease in and dust or water out.

During installation, check the shaft for burrs, splines or a rough finish, and make sure the sealing surface is smooth. Apply lubricant to the lip, then press the seal in with a suitable tool, keeping force even around the outer diameter. The 9.52 mm width must sit correctly in the housing to avoid distortion. If the shaft shows wear, an auxiliary lip may be worth considering.

If you are looking for an equivalent, provide the 5677 code or the current dimensions and we can search other brands or lines with compatible tolerances. Inspecting the shaft and housing before choosing a replacement is also wise, since heavy wear may call for greater interference or a repair sleeve.
