The DBH 1373Tef is a radial lip seal, designed to retain lubricant and stop the entry of dust, water or particles at the point where a shaft passes through a housing. It is mounted in gearboxes, pumps, electric motors and power transmission equipment, and works resting on the rotating shaft with the lip in contact. It is a wear part: when oil loss or the entry of dirt appears, it is replaced and the equipment seals again.

This item is identified with the designation 1373Tef and corresponds to a radial shaft seal of the DBH line. According to the product page data, the shaft diameter is 88 mm, with design A 435-R AH. For the housing diameter and height, the manufacturer's product page has values that must be confirmed before ordering, because in this record they appear as 0 and 000. Do not take those figures as real dimensions: they are verified against the DBH catalog at the time of inquiry.

Typical applications for a seal of this type are in equipment with a rotating shaft and internal lubrication: gearboxes, reducers, centrifugal pumps, motors, rollers and continuous process machines. In all these cases the seal performs two functions at once, retaining the oil inward and blocking dust or water outward. That is why it should be checked every time the assembly is disassembled and replaced if the lip is hardened, cut or visibly leaking.

To install a radial shaft seal, work with a clean shaft free of burrs, lubricate the lip with the same grease or oil as the equipment and press the part in perpendicular to the shaft. If the housing has a shoulder, use an installation sleeve or a flat-faced tube so as not to deform the lip. In the selection, in addition to the shaft diameter, the type of design, the lip material and the rotation speed matter; these data are cross-checked with the manufacturer's product page before confirming the replacement.

If you need an equivalent or a nearby size, send us the part number 1373Tef together with the shaft diameter and, if possible, a photo of the old part or the housing. With that we search the DBH line and compatible alternatives, and confirm which option fits without modifying the assembly. We can also check whether the A 435-R AH design has a direct replacement within the same oil seal category.
