The DBH 5312Pol is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a housing. Its three key dimensions are shaft 25 mm, housing 42 mm and height 6.00 mm, and it uses the Lx design. This is a standard replacement size, not a custom item. MR Industrial Accessories supplies this brand and can help you verify the size before you request a quote.

You identify the DBH 5312Pol by its code and by the three dimensions shown for it: shaft (d) 25 mm, housing (D) 42 mm and height (h) 6.00 mm. The Lx designation describes how the seal is built: a lip that presses against the shaft and an outer body that seats in the housing. Selection comes down to those dimensions and the service conditions, so it is a part you replace rather than design.

These seals are found in gearboxes, pumps, electric motors, drive shafts and process equipment where a rotating shaft passes through a housing and oil or grease must be kept separate from the surroundings. They also suit locations with dust or splashing, as long as the lip material works with the fluid and the operating temperature. In food, chemical or process settings, check that compatibility before you install a replacement.

Fitting a 25 x 42 x 6 mm seal calls for a clean shaft with no burrs or marks in the contact zone, and a housing that is not distorted. Lubricate the lip before you push the seal in, and seat it evenly without hitting the lip or the spring. If the shaft is worn, the same size may not seal properly; in that case, consider a design with an auxiliary lip. Fluid type, temperature and shaft speed all affect the choice.

To get a quote for code 5312Pol, send the shaft, housing and height dimensions, plus a photo or sample of the old seal if you have one. With that information we check options in the same radial shaft seal category. We also let you know whether the Lx design fits your application or whether a different lip type would be better.
