The DBH 1149 radial shaft seal is a lip seal that mounts on a 70 mm shaft and seals against a 111 mm housing, with a height of 10 mm. Its function is to retain lubricant inside the assembly and stop the ingress of dust, water or particles that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and transmission equipment that operate with rotating shafts and need a reliable barrier at the point where the shaft passes through the body.

This item is a radial shaft seal from the DBH line, identified with part number 1149. Its dimensions are 70 mm shaft, 111 mm housing and 10 mm height, with an Lx design. The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication and moderate speeds. The flexible lip rests on the shaft and the spring maintains contact pressure to compensate for small eccentricities and wear typical of service.

Typical applications for an oil seal of this size appear in equipment with medium-section transmission shafts: gearboxes, centrifugal pumps, electric motors, mixers and conveyors. In all cases it performs the same function: separating the lubricated side from the outside environment. When the oil seal works properly, the nearby bearing or bushing keeps its oil or grease film and the assembly gains service life. When it fails, lubricant loss, contaminant ingress and noise appear.

To install a radial shaft seal, it is advisable to check the condition of the shaft and housing before fitting it. The shaft must not show burrs, deep scratches or marks from previous seals in the lip contact area. The housing must be clean and free of deformation. During installation, lubricate the lip with the same oil or grease used in the equipment and press evenly, without striking the lip or the spring. If the shaft has a chamfer or a step, verify that the lip does not catch when entering.

If you need a nearby size or an equivalent, the most practical approach is to send us part number 1149 along with the shaft, housing and height dimensions shown on the equipment. With that data we can look for an alternative within the same radial shaft seal category or confirm whether the Lx design is suitable for your application. We can also guide you if the original seal has a different lip configuration or a material other than standard.
