A radial shaft seal from the DBH line, reference 6177, keeps lubricant inside the housing and holds dirt and moisture out wherever a shaft turns. The code maps to three measurements: 105 mm at the shaft, 152.80 mm at the housing bore and 16.00 mm of height, in the Lx design. Gearboxes, pumps, motors and process machinery are the usual homes for a seal of this size.

Reading the reference is straightforward. The 6177 number identifies the size, and the three figures that follow in the catalog describe where it fits: shaft 105 mm, housing 152.80 mm, height 16.00 mm. The Lx design points to a single lip with a spring, so the seal holds oil or grease on one side while blocking dust and water from the other. The lip rides on the rotating shaft; the outer diameter stays press-fitted in the bore.

This size turns up in medium and large rotating equipment: gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. The job is the same in each case, keeping lubricant where it belongs and shielding bearings or bushings from particles that shorten their life. In continuous process equipment the seal has to hold its performance across long running hours.

Fitting matters as much as the part. Inspect the shaft for burrs, nicks or scoring that could cut the lip, and confirm the housing bore is clean and round. Coat the lip with the same oil or grease the equipment uses, then drive the seal in with a flat tool that bears on the outer diameter, never on the lip. Keep it square to the shaft. Where the shaft shows wear, an offset-lip seal is worth considering. Speed, temperature and lubricant type all feed into the final choice.

When a replacement is needed, send reference 6177 plus the shaft and housing measurements. With those numbers we look at options in the DBH line and at other brands we supply. If the original is discontinued, we can also point you toward a standard size that can be adapted. The more detail you share about the equipment, the tighter the recommendation.
