This item is a DBH radial shaft seal identified as 9870Vit. Its dimensions are 79 mm shaft diameter, 99 mm housing bore and 9.60 mm height, with an Mx-R AH design. That combination defines a seal with a relatively low section for its diameter, intended for housings where axial space is limited. The Mx-R AH design corresponds to a seal with a retaining lip and a specific mounting configuration, which must be respected for it to seal properly.

Typical applications for a seal of this size are in rotating transmission equipment: gearboxes, pumps, electric motors, rollers and machine shafts that need to contain oil or grease and prevent the entry of dust or water. It is also used as a closure in bearing housings and machined housings where the shaft rotates at moderate speeds. In all cases, the seal runs against a ground shaft surface and a housing with the correct diameter and depth.

To install it, check that the shaft is clean, free of burrs or marks, and lubricate the lip before sliding it on. The seal must enter perpendicular to the housing, without blows that could deform the casing. If the shaft is worn or has a marked track, it is advisable to evaluate a seal with the lip in a different position or a wear sleeve. Selection depends on speed, temperature and the fluid to be retained: with that data, the lip material and spring type are defined.

If you need an equivalent, send us the code 9870Vit and the shaft and housing dimensions. We can look for an oil seal from another brand with the same dimensions or suggest a design variant if the installation allows it. It is also advisable to review the manufacturer's product page to confirm tolerances and material, especially if the equipment operates at high temperatures or with aggressive fluids.
