A rotary shaft needs a reliable barrier to keep lubricant in and contaminants out. The DBH 9105 oil seal does exactly that, with a 20 mm shaft, 45 mm housing and 7 mm width, and the Lx construction from the DBH line. MR Industrial Accessories supplies this seal and helps you confirm it fits your application.

The DBH 9105 is a radial shaft seal. Its code identifies a specific size and design: shaft 20.00 mm, housing 45.00 mm, width 7.00 mm. The Lx designation refers to the internal build of the seal, which pairs a sealing lip with a metal case. If you are replacing a worn seal on a 20 mm shaft that runs in a 45 mm bore, this is the direct match.

You will find seals like this in gearboxes, pumps, electric motors, conveyor rollers and other power transmission assemblies. The lip holds oil or grease inside while blocking dust, water and particles that would otherwise reach bearings and gears. Plants in food processing, cement, mining and general manufacturing rely on them to keep rotating equipment running without unexpected stoppages.

Before installing, check the shaft surface for burrs or wear at the lip contact point, and make sure the housing bore is clean and round. Coat the lip with the same lubricant used in the machine, then press the seal in squarely, applying even force around the outer edge. If the shaft shows a groove, an auxiliary lip or a wear sleeve may be the better choice. Lip compound selection should also match the operating temperature and the fluid being sealed.

Looking for a cross-reference? Send the full part number, the three dimensions and a photo of the old seal. Our team can identify alternatives in other brands or series that serve the same purpose, and can explain the Lx design and its variants for your specific equipment. Other sizes in the DBH line are also available on request.
