This item is a radial shaft seal from the DBH line, identified as 8335Sil. Its nominal dimensions are 28.00 mm shaft diameter, 40.00 mm housing diameter and 8.00 mm height. The A 170 design defines the geometry of the lip and the metal case, intended for standard housings. It is a compact-section part that works with the lip in direct contact on the shaft, generally with a spring that maintains sealing pressure.

It is used in gearboxes, pumps, electric motors, drive shafts and process equipment where oil or grease must be contained and external contamination prevented. It also appears in applications with splashing, dust or frequent washing, where the seal protects bearings and gears. As a wear part, it is replaced when lubricant loss, noise or dirt ingress into the assembly appears.

To install it, check that the shaft is clean, free of burrs and marks, and that the sealing surface has the appropriate roughness. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking it unevenly. If the housing has burrs or the shaft shows wear, it is advisable to consider an alternative design. The selection depends on the speed, temperature and type of lubricant in the equipment.

If you need an equivalent, send us part number 8335Sil or the shaft, housing and height dimensions along with a photo of the old seal. A drawing or the equipment designation also works. With that data we review alternatives within the DBH line and other brands we sell, and we confirm the option that fits best before quoting.
