MR Accesorios Industriales supplies this official brand and advises you on choosing the right seal.

This item is a DBH radial shaft seal, designation 8509Vit, with an Lx-R-AH design. Its standard dimensions are: shaft diameter 90 mm, housing diameter 110 mm and height 8.50/10.00 mm. The Lx-R-AH design indicates a configuration with a sealing lip, metal reinforcement and a profile that combines dust protection and oil retention. The double height (8.50/10.00 mm) allows it to adapt to housings with different mounting depths, as long as the nominal shaft and bore dimensions are respected.

Seals in this series are used in applications with continuous rotation and the presence of lubricant. They are common in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. They also appear in agricultural and road machinery, where dust and moisture demand effective sealing. By keeping lubricant in and contaminants out, they protect bearings and gears, reducing premature wear and unplanned downtime.

To install a seal, check that the shaft is within the recommended tolerance, free of burrs or marks, and that the housing has the correct diameter and depth. The lip must be lubricated before installation and the part must enter perpendicular, without blows that deform the reinforcement. When selecting, in addition to the dimensions, consider the rotation speed, working temperature and the type of fluid to be retained. If the original seal has a different height, consult a specialist about compatibility.

If you need a seal equivalent to the 8509Vit or a nearby size, the most practical approach is to send us the full part number and, if possible, a photo of the part and the shaft and housing dimensions. With that data we can look for an alternative within the same brand or another line we supply. We can also advise you if the Lx-R-AH design is not suitable for your application and another lip profile or material should be evaluated.
