The DBH 5712 is a radial shaft seal built to keep oil or grease contained on rotating shafts while blocking contaminants. It fits a 55.56 mm shaft in an 81 mm housing with an 11.90 mm height, and its Lz lip design includes a spring for consistent contact. This seal is a common replacement item in gearboxes, pumps, and electric motors, and MR Industrial Accessories LLC supplies it as a brand while helping you confirm the right choice for your equipment.
The part number 5712 identifies a DBH seal with three key dimensions: shaft 55.56 mm, housing 81 mm, and height 11.90 mm. The Lz designation refers to a lip configuration with a spring, intended to retain lubricant and exclude dirt or moisture in rotating assemblies. It is a precision component that presses into the housing and seals against the shaft surface.
You will typically find this seal in gearboxes, reducers, centrifugal pumps, electric motors, and power transmission equipment. In those systems, it prevents oil leaks and keeps dust or water out, which helps protect bearings and gears. Industrial machinery, process equipment, and heavy-duty vehicles often use seals of this size on shafts around 55 mm.
For proper installation, inspect the shaft for burrs or wear at the contact area and make sure the housing is clean and undistorted. Apply a compatible grease to the lip before fitting, and press the seal in squarely with a suitable installation tube. When selecting a seal like the 5712, consider peripheral speed, operating temperature, and the fluid being retained. If you are unsure, our team can review your application.
