The DBH 5857 radial shaft seal is a lip seal mounted on a rotating shaft to retain oil or grease and prevent the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment. Its dimensions are 31.75 mm shaft, 42.82 mm housing and 9.52 mm height, with Lz design. At MR Accesorios Industriales we sell it as part of our line of seals and oil seals for industrial maintenance.

This item is a DBH radial shaft seal, identified with part number 5857. Its dimensions are 31.75 mm shaft diameter, 42.82 mm housing diameter and 9.52 mm height. The Lz design corresponds to a sealing lip with a spring and a specific construction that gives it flexibility and sealing performance. The lip elastomer runs on the shaft and the metal case is press-fitted into the housing. It is a standard replacement part within the radial shaft seal category.

Typical applications for a seal such as the 5857 appear in equipment with rotating shafts where lubricant must be contained and contaminants blocked. It is found in gearboxes, centrifugal pumps, electric motors, conveyor rollers and machine tools. It is also used in agricultural implements and road equipment. Seal selection depends on shaft diameter, available housing and working conditions: temperature, peripheral speed and type of lubricant. In all cases, the lip must remain lubricated and rest on a ground surface.

To install a radial shaft seal, check that the shaft has no burrs or marks and that the housing is clean and free of deformation. The seal is driven in with a tube or spacer that rests on the metal edge, never on the lip. Before fitting it, lubricate the lip with the same grease or oil used in the equipment. If the shaft shows wear, consider a seal with an offset lip. Correct alignment between shaft and housing prevents premature leaks and extends the service life of the seal.

If you need a seal equivalent to the 5857, send us the part number and the dimensions shown on the nameplate or drawing. We can also help if the housing has a different tolerance or if the shaft is worn. At MR Accesorios Industriales we sell the DBH brand and have alternatives within our seals line. The more data you give us — shaft diameter, housing, height and type of lubricant — the more accurate the proposal will be.
