The DBH 8406 is a radial shaft seal with part number 8406. Its three key dimensions are: shaft 39.42 mm, housing 80.27 mm, and height 14.25 mm. Design A 055-R specifies the lip geometry and case style. The seal combines a flexible lip with a rigid metal case, allowing it to press into the housing and maintain contact with the shaft to retain lubricant and block dust and water.
Seals like this are used in centrifugal pumps, electric motors, gearboxes, reducers, compressors, and power transmission systems. Their role is to protect bearings and gears from particle ingress and prevent oil leaks. In industrial maintenance, a failed seal can lead to lubricant loss, accelerated wear, and unexpected downtime.
Proper selection requires matching the shaft, housing, and height dimensions to your equipment. The shaft surface should be free of burrs and have appropriate hardness and roughness to avoid damaging the lip. During installation, lubricate the lip with the system's oil or grease, press the seal perpendicular to the shaft, and avoid impact. If the housing is worn, consider a seal with an oversized case or a repair sleeve.
If you need a replacement or equivalent, provide part number 8406 or your equipment dimensions. MR Industrial Accessories distributes seals and radial shaft seals and can guide you to the best option. We also offer mounting tools and compatible lubricants to support correct installation and extend seal life.
