The DBH 8999 is a radial shaft seal that keeps oil or grease contained where a shaft passes through a housing, while also blocking dust and water from the outside. You will find it in gearboxes, pumps, electric motors and power transmission equipment, where lubrication has to stay in and contamination has to stay out. MR Industrial Accessories supplies this brand and quotes it on request.

The part number is 8999. Its three key dimensions are: shaft 85 mm, housing 145 mm, height 18.00 mm. The design is Lx, which sets how the lip and the seal body are arranged. Those three values are what you match to the drawing: the inner diameter goes on the shaft, the outer diameter fits the housing bore, and the height tells you how much room the seal takes up in the seat. Confirm all three against the equipment before you install.

Seals in this size range show up on medium-section shafts: gearboxes, reducers, centrifugal pumps, electric motors, mixers and conveyors. In every case the seal runs against a rotating shaft, holds the lubricant in the assembly and keeps dust, chips and wash water out. You will also see it in process equipment where the seal has to handle the industrial oils and greases normally used in that service.

When you select a seal, look at the shaft surface first. Wear or a deep mark in the contact area will stop the lip from sealing, even if the size is right. Check the housing for burrs or deformation as well, and lubricate the lip before installation. Press the seal in perpendicular to the shaft using a tube or spacer that pushes on the body, never on the lip, so the lip is not damaged during assembly.

If 8999 is not the part you need, or the shaft or housing measures differently, there is likely an equivalent in the same radial shaft seal category. Send the original part number, the shaft, housing and height dimensions, and a photo or detail of the equipment. We compare that data against the available options and propose the closest fit.

To request a quote for the DBH 8999 seal or to ask about an equivalent, send the part number by WhatsApp or email along with the shaft and housing dimensions. If you still have the old seal, a photo with a caliper across the three dimensions makes confirmation quick. We reply with the applicable alternative and coordinate the order.
