The DBH 5104 is a radial shaft lip seal built to hold lubricant in place and keep dust, water and other contaminants out of rotating assemblies. Its three key measurements are a 34.93 mm shaft, a 53.97 mm housing bore and an 11.11 mm width, which place it within the DBH 5100 series. Maintenance teams reach for it when a machine has a standard machined cavity and needs a dependable barrier against oil loss and outside debris.

Reading the designation is straightforward: the 5104 code ties the seal to a fixed size envelope, with 34.93 mm at the shaft, 53.97 mm at the housing and 11.11 mm across its height. The Lz design points to a lip-and-spring construction, where the spring keeps steady pressure on the sealing lip as the shaft turns. The DBH brand is one of the lines MR supplies, so each piece arrives with its own identification for traceability. In service, the seal sits in a machined cavity and works against the rotating shaft.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission equipment. In each case its job is the same: keep the lubricant where it belongs and stop particles from getting in, since grit that reaches bearings and gears speeds up wear. Agricultural, road and process machinery also use it, where weather exposure and frequent washdowns put the seal under regular stress.

Choosing the right seal starts with confirming the shaft, housing and height figures against your equipment. Peripheral speed, operating temperature and the lubricant in the system all affect how long a seal lasts. At installation, coat the lip with the same oil or grease the system uses, keep the spring from being knocked out of position, and check that the shaft surface is free of burrs or heavy wear. Handling it carefully at this stage goes a long way toward avoiding early leaks.
