The DBH 5254 is a radial shaft seal built to hold lubricant in and keep contaminants out where a shaft turns. With a 22 mm shaft, 35 mm housing bore and 6 mm width, it fits tight assemblies. This is one of the DBH seal references we supply for industrial maintenance and repair work.

The code breaks down simply: 5254 identifies the seal, and the dimensions read shaft 22.00 mm, housing 35.00 mm, width 6.00 mm. The Lx design means a sealing lip with a spring, a common choice when oil or grease has to stay on one side and dust on the other. Before fitting, measure the shaft and the bore; a seal only works when both match.

You will find seals like this in pumps, electric motors, gear reducers, gearboxes and transmission shafts. Their job is to protect the bearing and gear areas from lubricant loss and from grit working its way in, which is why they are a standard item in preventive and corrective maintenance. Usually they come out together with other worn parts.

Dimension is not the only thing to check. Shaft speed, temperature, the lubricant in use and any pressure difference across the seal all affect how long it lasts. The Lx design suits moderate speeds and low pressures. At installation, oil the lip, keep it away from sharp edges and seat the seal square to the shaft; most early leaks come from handling, not from the seal itself.

If you are replacing a worn seal or matching an equivalent, send the code 5254 or your measured dimensions. We supply seals, bearings, mounted units, power transmission parts and maintenance tools to customers across the United States and in Latin America, and we can suggest a suitable alternative.
