The DBH 5717 is a radial shaft seal of the lip type, used to keep lubricant in and contaminants out of rotating assemblies. Its dimensions are 41.28 mm for the shaft, 82.58 mm for the housing bore and 12.70 mm for the height, and it uses the Lz design. The seal is pressed into the housing and its lip runs against the rotating shaft, making it a service part in gearboxes, pumps, motors and similar equipment. MR Industrial Accessories supplies this brand and can help you confirm the correct seal for your application.

Part number 5717 identifies a DBH radial shaft seal with these dimensions: shaft 41.28 mm, housing 82.58 mm, height 12.70 mm. The Lz designation refers to a single lip with a spring, intended for shafts that turn in one direction. An elastomer lip bears against the shaft to form a dynamic barrier against lubricant loss and particle entry, while the metal outer case holds the seal firmly in the housing bore.

Seals of this size are common in gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. The job is always the same: hold oil or grease inside the assembly and block dust, water or chips from reaching bearings and gears. Because the lip wears over time, the seal is replaced when a leak appears or as part of scheduled maintenance.

Proper installation starts with clean, burr-free and scratch-free shaft and housing surfaces. Apply the same oil or grease used in service to the lip before fitting. Use a tool that presses on the metal case, never on the lip, and check that the seal sits square to the shaft at the correct depth. If the shaft is worn, a repair sleeve or a different lip position may be needed.

For an equivalent seal, send part number 5717 or the shaft, housing and height dimensions. With that information we can look for alternatives in other brands or configurations that match your equipment. We can also advise on elastomer type or lip design based on temperature, speed and lubricant.
