The DBH 1135 oil seal is a single-lip radial shaft seal with a spring, designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 50 mm shaft diameter, 64 mm housing diameter and 8 mm height place it in medium-size power transmission equipment and pumps. It is a wear part: when the lip hardens or a leak appears, it is replaced. At MR Accesorios Industriales we carry it.

The DBH 1135 is a radial shaft seal of Lx-R H design, with a sealing lip and internal spring. Its dimensions are 50 mm shaft diameter (d), 64 mm housing diameter (D) and 8 mm height (h). The flexible lip runs on the rotating shaft and the spring maintains contact pressure; the outer body seats in the housing. That combination seals oil or grease and blocks the entry of dust and water. It is fitted in gearboxes, pumps, motors and rollers, among other equipment with a rotating shaft.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In every case it performs the same function: confining the lubricant inside the assembly and preventing it from escaping along the shaft. It also protects bearings and gears from the entry of particles, which extends the service life of the assembly. If the equipment runs with heavy vibration or temperature, it is advisable to check the condition of the lip more often.

For installation, check that the shaft has no burrs or wear 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 perpendicular to the shaft, without striking it unevenly. When selecting a replacement, in addition to the dimensions, take into account the type of fluid, the working temperature and the shaft speed. If the original seal has a different design, contact us and we will look for the alternative that fits best.

If you need an equivalent or a nearby size, send us the part number 1135 or the dimensions of the old seal: shaft diameter, housing diameter and height. With that data we check the DBH line and compatible alternatives. We can also advise you if the housing has a shoulder or if the shaft shows wear. The more precise the information, the faster we reach the right part.
