The DBH 1150 radial shaft seal is a lip seal that stops lubricant from escaping and blocks dust and water from entering equipment with a rotating shaft. Because of its dimensions —122.20 mm shaft, 152.40 mm housing and 7.14 mm height— it is used in gearboxes, pumps and medium-size transmissions. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a radial shaft seal from the DBH line, identified by the code 1150. Its dimensions are d 122.20 mm (shaft), D 152.40 mm (housing) and h 7.14 mm (height). The Mz design corresponds to a single-lip configuration with a spring, intended to retain oil or grease on a shaft rotating inside a machined cavity. The elastomer runs against the shaft and the metal case is press-fitted into the housing.

Typical applications for a seal of this diameter include gearboxes, centrifugal pumps, mixers, conveyors and power transmission equipment. In every case it performs the same function: preventing lubricant leaks to the outside and stopping contaminants from entering that accelerate wear on bearings and gears. It is a frequently replaced part in industrial maintenance.

For installation, check that the shaft has no burrs or deep marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip before inserting it and fit the seal with a support tube that presses on the metal case, never on the lip. If the shaft shows wear, consider a nearby size or a design with an offset lip so the failure is not repeated.

If you need an equivalent or a close size, send us the code 1150 along with the shaft, housing and height dimensions, and the type of fluid to be retained. You can also send a photo of the old part or the housing drawing. With that data we review alternatives within the same radial shaft seal category and confirm which option fits.
