The DBH 5715 is a radial shaft seal that closes the gap where a rotating shaft exits a housing. Its job is to hold lubricant inside the assembly and keep dust, water and other particles out. Seals of this type are common in gearboxes, pumps, electric motors and transmission equipment, and the 5715 is a standard replacement size in industrial maintenance work.

The designation 5715 refers to the size of the seal. Reading the dimensions in order: shaft 57.15 mm, housing 81 mm, width 11.11 mm. The Lz design describes the lip and metal body geometry, made to run in continuous contact with the shaft under lubrication. The cross section is compact, which suits housings with limited axial room.

You will find this seal on equipment where a shaft passes through a crankcase: gearboxes, centrifugal pumps, motors, mixers, conveyors and machine tools. In those spots it stops oil or grease from escaping and blocks contaminants from getting in, which helps protect bearings and gears. It is also a routine replacement when maintenance inspection finds sweating or lubricant loss.

Before installing, confirm the shaft is free of burrs, splines and wear on the contact track, and that the housing is clean with no dents. Lubricate the lip, then seat the seal perpendicular to the shaft without distorting it. If the shaft already shows a visible groove, you can shift the mounting position slightly or replace the part. Lubricant type, speed and working temperature all affect the selection.

If you are looking for an equivalent, send the code 5715 together with the shaft, housing and width dimensions and a description of the application. With that information our team can check alternatives in the DBH line or other brands we supply, confirming dimensional compatibility first. We can also help when the identification on the original seal can no longer be read.
