A lip seal like the DBH 6180 keeps lubricant inside the housing and keeps dust, water and particles out, working against a rotating shaft. The code covers a shaft of 125 mm, a housing bore of 150 mm and a height of 15.00 mm in the Lx design, which is a single lip with a spring. It is treated as a replacement item on equipment that runs continuously.

The part number is 6180 and it belongs to the DBH line. Reading the code: d is the shaft, D is the housing and h is the height, so 125 mm shaft, 150 mm housing and 15.00 mm height. Lx tells you there is one lip with a spring behind it, which keeps pressure on the shaft race as it turns. The elastomer lip rides on the shaft, while the outer diameter holds the fit in the bore.

Typical locations are gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment, plus machine tools, agitators and lubrication systems where oil or grease must stay in and bearings must stay protected. Because it is a wear part, a lip that hardens or shows marks will start to leak. Replacing it at that point is cheaper than letting the shaft score or the lubricant become contaminated.

Before ordering, measure the shaft, the housing bore and the height and compare them with the values above. Look at the shaft race as well: a groove or visible wear means a new lip will not seat correctly. Fit the seal square to the shaft, coat the lip with the same oil or grease used in the application, and avoid hitting it during installation. If the original had an auxiliary lip or a specific compound, check that detail against the manufacturer's data before substituting.

To get a quote for 6180, send the dimensions of the old seal, meaning shaft, housing and height, along with a photo. The code marked on the seal or the equipment model is also useful. With that information we can look for an equivalent in the DBH line or in other brands we supply, keeping the dimensions and the design type the same.
