The DBH 5025Sil is a radial shaft seal built for rotating shaft positions. It measures 20 mm at the shaft, 40 mm at the housing bore and 6.00 mm in height, so it works as the barrier that keeps lubricant inside the assembly and keeps dust and moisture out. Gearboxes, pumps and motors depend on this kind of sealing to protect bearings and gears. MR Industrial Accessories supplies this brand and can help you match the seal to your equipment.
The code breaks down into the DBH line plus the designation 5025Sil. The Lx design refers to a sealing lip combined with a spring, which maintains steady contact against the shaft. The elastomer compounds used in this seal resist oils and greases, and the metal outer case allows it to be pressed into the housing bore.
You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and transmission systems. In each of those machines it holds lubricant in place and keeps outside contaminants from reaching the interior. Industrial machinery, agricultural equipment and vehicles are common places where this size shows up, particularly where sealing has to hold up under demanding conditions.
Before pressing the seal in, check that the shaft and housing bore are clean and free of burrs. Apply the same oil or grease used in the equipment to the lip, then press with a tool that contacts the outer ring only, never the lip. Keep the pressure even until the seal reaches the bottom of the housing. If the shaft surface is worn, an auxiliary lip or a wear sleeve may be worth considering.
If you are looking for a replacement, send us the code on WhatsApp or by email. We can search other brands or series that share the same dimensions and performance, and we can advise on lip material and spring type based on the temperature, speed and fluid involved.
