The DBH 8999 radial shaft seal is a lip seal that closes off the passage of oil or grease at the point where a shaft passes through a housing, while at the same time preventing dust and water from entering from outside. It is used in gearboxes, pumps, electric motors and power transmission equipment, where lubrication must stay inside and contamination outside. MR Accesorios Industriales carries this brand and will quote it for you on WhatsApp.

This item is identified by part number 8999 and corresponds to a radial shaft seal with a 85 mm shaft diameter, 145 mm housing diameter and 18.00 mm height. The indicated design is Lx, which defines the configuration of the lip and the seal body. With those three values the part is located on the drawing: the shaft enters the inner diameter, the housing takes the outer diameter and the height sets how much space the seal occupies in the seat. Before mounting, it is advisable to verify that the three dimensions match those of the equipment.

Typical applications for a seal of this size appear in equipment with medium-section shafts: gearboxes, reducers, centrifugal pumps, electric motors, mixers and conveyors. In all those cases the seal works on a rotating shaft and retains the lubricant inside the assembly, while at the same time blocking the entry of dust, chips or wash water. It is also found in process equipment where the seal must withstand contact with commonly used industrial oils and greases.

To choose the right seal, check the condition of the shaft surface: wear or a deep mark in the contact area means the lip will not seal, even if the size is correct. It is also advisable to check the housing for burrs or deformation, and to lubricate the lip before mounting it. The seal is inserted perpendicular to the shaft, with a tube or spacer that bears on the body and not on the lip, so as not to damage it during assembly.

If part number 8999 is not the one you need, or if the shaft or housing has a different size, an equivalent or a nearby size can be found within the same radial shaft seal category. For that, it is advisable to send the original part number, the shaft, housing and height dimensions, and a photo or detail of the equipment where it is mounted. With that data it is compared against the available alternatives and the option that fits best is proposed.

To request a quote for the DBH 8999 oil seal or to ask about an equivalent, send the part number by WhatsApp to MR Accesorios Industriales along with the shaft and housing dimensions. If you have the old seal at hand, a photo with a caliper over the three dimensions helps confirm the part without hassle. With that we will reply with the corresponding alternative and coordinate the order.
