This DBH 6611 radial shaft seal is a lip seal that mounts on the shaft and against the housing to retain lubricant and block the entry of dust, water or particles. Its Lx design combines a sealing lip with a metal case that fits into the cavity under pressure. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotates inside a fixed housing.

The DBH 6611 has a 135 mm shaft diameter, a 171.10 mm housing diameter and a 15.00 mm height. The Lx design corresponds to a seal with a single sealing lip and an outer metal case, designed for press fitting into a cylindrical housing. The 6611 nomenclature identifies the construction size within the DBH line, and the part number lets you order the same item without ambiguity. It is a wear component: over time the lip hardens or wears and starts to lose oil.

Typical applications are gearboxes, speed reducers, centrifugal pumps, electric motors, rollers and power transmission equipment. In all these cases the seal separates the oil or grease from the environment and prevents the lubricant from migrating outward or dirt from entering the bearing. It is also used in agricultural machinery, washing equipment and systems where there is splashing or dust. If the shaft rotates with high eccentricity or the temperature is high, a different compound should be evaluated.

To select the seal correctly, verify that the shaft diameter, housing diameter and height match those of the DBH 6611. The shaft must be smooth, free of burrs and tool marks, with a suitable surface finish and sufficient hardness so it does not wear the lip. The housing must be clean, free of dents and with the entry chamfer in good condition. When mounting it, lubricate the lip with the same oil used in the equipment, use an installation tool that does not deform the case and avoid striking the seal directly with a hammer.

If you need a nearby size or an equivalent, send us the 6611 part number along with the shaft, housing and height measurements. It also helps if you tell us the equipment where it is mounted, the type of lubricant and the working temperature. With that data we can look for an alternative within the DBH line or from other brands we carry. If the original seal has a special design, such as a double lip or a dust guard, we evaluate it against the manufacturer's data sheet.

MR Accesorios Industriales carries the DBH brand as an official brand. If you want a quote for the DBH 6611 oil seal or to ask about a similar size, write to us on WhatsApp with the part number and the measurements. We will reply with the alternative that best fits your equipment.
