The DBH 6247 radial shaft seal is a single-lip seal with a spring, designed for rotating shafts. Its function is to retain the lubricant inside the housing and prevent the entry of dust, water or particles. It is press-fitted into covers, cases and housings, and runs on the shaft with a film of oil that ensures sealing and low friction. It is a wear part: when the lip hardens or becomes marked, it should be replaced to avoid losses and contamination.

This DBH 6247 oil seal has an 18 mm shaft diameter, a 40 mm housing diameter and a 10 mm height. The Lx design indicates that the sealing lip faces inward, with the spring visible on the lubricant side. The outer body is metal, with a coating that favors the fit in the housing. The lip, made of elastomer, rests on the shaft with slight radial pressure to seal without slowing rotation.

It is used in pumps, electric motors, gearboxes, gear cases and power transmission equipment. It also appears in machine tools, mixers, conveyors and agricultural equipment. In all cases, the selection of the seal depends on the shaft diameter, the housing and the available width. The Lx design is common in applications where the lubricant is on the inner side and a simple barrier against external dirt is sought.

To mount it, clean the housing and the shaft, and check that there are no burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in service before sliding it on. Insert the seal perpendicularly, without striking the elastomer, using a tube or spacer that rests on the outer ring. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip. Eccentricity and shaft play also affect service life.

If you need an equivalent or a nearby size, send us the part number 6247 or the dimensions 18 x 40 x 10 mm by WhatsApp. We can look for alternatives in other brands or configurations, always respecting the mounting dimensions. It is also advisable to check the condition of the shaft: a new lip on a worn track may not seal well. With the correct data, we will send you the available options to quote.
