The DBH 5193Sil is a radial shaft seal that sits in the housing bore and seals against the rotating shaft. It keeps lubricant where it belongs and blocks dust, water and particles from getting in. The designation tells you the fit: 64 mm shaft, 80 mm housing bore, 8 mm height, with an Lz-R lip and case design. MR Industrial Accessories supplies this seal through its seals and oil seals line.

Reading the code is straightforward once you know the layout. The 5193Sil number identifies the seal in the DBH range, and the dimensions follow the usual order: d for the shaft, D for the housing bore, h for the height. Here that means 64 mm, 80 mm and 8.00 mm. The Lz-R designation describes how the lip and the outer case are built, which matters when radial space is tight and the shaft still needs a dependable seal.

Seals in this size range turn up in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. The job is always the same: hold the oil or grease in, keep contaminants out, and protect the bearings and gears behind the seal. These units typically run at moderate shaft speeds with lip materials suited to the operating temperature of the assembly.

Before you order, confirm that the shaft and housing bore match the seal. The 64 mm and 80 mm figures are the ones that decide whether the fit works; get them wrong and you get leaks or early wear. When pressing the seal in, coat the lip with lubricant, keep it clear of burrs on the shaft and the tool, and seat it square to the housing. If the original seal was not Lz-R, verify compatibility before you swap it in.

If you are chasing an equivalent, the fastest route is to send the 5193Sil code or your measured shaft and housing dimensions. With that we can search across the DBH line and the other brands we carry, and help you work out whether a similar-performing replacement fits your equipment.
