The DBH 5688 radial shaft seal is a lip seal that keeps oil or grease contained on a rotating shaft and blocks dust and water from entering the assembly. With a 47.63 mm shaft, 68.22 mm housing and 12.70 mm height, it fits gearboxes, pumps, electric motors and power transmission equipment. As a wear part, it is replaced when lubricant loss or contaminant entry is detected.

This radial shaft seal carries the DBH brand and part number 5688. The dimensions are shaft 47.63 mm, housing 68.22 mm and height 12.70 mm. The Lz design defines the lip and outer body geometry. It is a single-lip seal with a spring, made to hold lubricant on a shaft rotating inside a cavity. The 5688 number follows the manufacturer's catalog and should not be read as inch dimensions or confused with numbers from other lines.

Seals of this size are common in gearboxes, speed reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In every case the job is the same: retain lubricant inside the assembly and keep out dust, water or particles that speed up wear on bearings and gears. It also serves as a secondary closure where a pressure difference exists between the interior and the environment.

Correct installation starts with checking the shaft for burrs or deep marks in the contact area and making sure the housing is clean and not deformed. Lubricate the lip before insertion and press on the outer body with a tube or shim, never on the lip. Selection depends on shaft speed, working temperature and lubricant type; if those values are not defined, confirm them with the supplier before ordering.

To request a quote for part number 5688, send the part number or the three dimensions — shaft, housing and height — plus the application type, and we can look for an equivalent from another brand. With that information we can locate the alternative within the DBH line or other brands we supply. We can also help if the original seal has a special design, such as a double lip or reinforced metal body, so the replacement is the right one.
