The DBH 9851Vit is a single-lip radial shaft seal built for rotating shafts measuring 45 mm in diameter. It keeps lubricant where it belongs inside the housing while blocking dust, water and other contaminants from getting in. Installation is by press fit into a 75 mm bore, with a 10 mm overall height. Because it is a wear part, it should be swapped out once oil weeping or bearing noise shows up.

Reading the size off the code is straightforward: shaft 45 mm, housing 75 mm, height 10 mm. The Lx-R AH design pairs a radial sealing lip with an auxiliary exclusion lip, which adds protection against outside contaminants. A metal outer body lets the seal be pressed into rigid housings. Within the DBH line, the 9851Vit designation pins down both the dimensions and the design type.

Typical service covers gearboxes, pumps, electric motors, drive shafts and process equipment running in continuous rotation. You will often find it in settings with moderate dust or moisture, such as conveyors, mixers and agricultural machinery. It also works as a replacement item during preventive maintenance on bearings and bushings, where holding lubricant in place protects the assembly.

When selecting a replacement, confirm that shaft, housing and height match the original part. The shaft surface should be ground and free of splines so the lip is not damaged. Lubricate the lip with the same oil or grease used in the equipment before mounting, and check the housing for burrs. Use a press or a suitable tool, applying even force on the outer diameter.

If you need an equivalent from another brand, send us the code 9851Vit or the dimensions 45x75x10 mm and we can look at the options. We can also advise when the Lx-R AH design is not the right fit for your application and a different lip type or material is needed. MR Industrial Accessories LLC supplies DBH.
