For rotating shafts, the DBH 8503Pol radial shaft seal keeps lubricant in and contaminants out. It measures 35.00 mm at the shaft, 49.00 mm at the housing bore, and 6.00 mm in height. The Lx-R design identifies a lip seal with a spring. MR supplies this brand and can help you match the right seal to your equipment.

You will find the DBH 8503Pol in gearboxes, pumps, electric motors, and other power transmission assemblies. Its job is to protect bearings and gears by holding oil or grease in place and blocking dust, water, and particles that cause wear. As a wear part, it should be replaced when leaks appear or when the adjacent bearing starts making noise.

The Lx-R designation points to a single sealing lip with a spring, a common choice for lubricated rotating shafts. When selecting a seal, consider shaft speed, operating temperature, and the lubricant in use. The spring-loaded lip works well for rotating shafts with moderate pressure. In dirty or wet conditions, a seal with an auxiliary lip or dust lip may be a better fit.

Before installation, make sure the shaft and housing are clean and free of burrs or scratches. Lubricate the lip, then press the seal in squarely. If you need a replacement, send the original part number, the shaft, housing, and height dimensions, and a photo of the part. With that information, we can look for alternatives in the same series or from other brands we carry.
