The DBH 8509Vit is a radial shaft seal with an Lx-R-AH profile. It measures 90 mm at the shaft, 110 mm at the housing, and 8.50/10.00 mm in height. This seal keeps lubricant in and contaminants out of rotating equipment, helping bearings and gears last longer. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your application.

The 8509Vit uses the Lx-R-AH design, which combines a sealing lip, a metal case, and a profile that handles both oil retention and dust exclusion. The dual height of 8.50/10.00 mm lets it fit housings with different mounting depths, provided the nominal shaft and bore sizes match. The part number 8509Vit identifies this specific size and design within the DBH line.

You will find seals like this in gearboxes, centrifugal pumps, electric motors, conveyor rollers, and power transmission equipment. They are also common in agricultural and road machinery, where dust and moisture are constant concerns. By sealing the shaft, they protect bearings and gears from premature wear and reduce the risk of unplanned downtime.

Proper installation matters. Check that the shaft is within tolerance and free of burrs or marks, and that the housing has the correct diameter and depth. Lubricate the lip before pressing the seal in, and keep it perpendicular to avoid deforming the metal case. When selecting a seal, consider rotation speed, operating temperature, and the fluid being retained. If the original seal has a different height, ask about compatibility before substituting.

If you need a seal equivalent to the 8509Vit, send the full part number along with a photo of the part and the shaft and housing dimensions.

We can also advise if the Lx-R-AH design is not ideal for your application and another lip profile or material should be considered.
