The DBH 8909 is a radial shaft lip seal built for a 42 mm shaft, a 68 mm housing bore, and a 10 mm height. It keeps lubricant in and blocks dust, water, and other contaminants from reaching bearings and gears. You will find it in gearboxes, pumps, electric motors, and power transmission equipment where sealing integrity matters. MR supplies this brand and helps you match the right seal to your application.

This seal belongs to the DBH line and carries the code 8909. Its dimensions are shaft 42 mm, housing bore 68 mm, and height 10 mm. The Lx design means a single sealing lip with a spring, intended for rotating shafts that run with lubrication. Use the 8909 code to confirm that the dimensions fit your shaft and housing before ordering.

Common uses include gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. In these assemblies, the 8909 seal protects bearings and gears from contaminants and stops oil or grease from escaping. Treat it as a wear part: replace it when you see leaks or hear unusual noise around the seal area.

Before installation, inspect the shaft for burrs or wear and clean the sealing surface. Lubricate the lip with the same oil or grease used in the equipment, then press the seal in squarely. The housing must be free of dents and have a proper chamfer so the lip is not damaged. If the shaft shows a deep groove, look at a seal with a wear sleeve or a different size.

If you need an equivalent, send the code 8909 or the shaft and housing dimensions. MR compares options from other brands and suggests the one that fits your needs. We can also help when space is tight or when a special material is required for high temperatures or high surface speeds.
