The DBH 1114 seal is a radial lip seal designed to retain lubricant and block the entry of dust, water or particles in equipment with a rotating shaft. It mounts on a 45 mm shaft and fits into a 72 mm bore, with a total height of 12.0/19.5 mm and design A 103-R H. It is a wear part: when oil loss, sweating on the housing or dirt ingress appears, it should be replaced before the bearing fails.

This item is a radial shaft seal from the DBH line, identified by code 1114. Its dimensions are 45 mm shaft, 72 mm housing and 12.0/19.5 mm height, with design A 103-R H. Design A 103-R H corresponds to a seal with a sealing lip and metal reinforcement, suitable for rotating shafts with lubrication. The double height 12.0/19.5 mm indicates that the part has a 12 mm body and a lip or dust guard that reaches 19.5 mm, a detail that affects the clearance inside the housing.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a housing and oil or grease needs to be contained. It also appears in agricultural machinery, conveyors and process equipment. In all these cases it performs two functions: retaining the lubricant on the inner side and stopping the entry of environmental contaminants, which is what wears bearings and bushings the most.

To choose the right seal, verify that the shaft diameter, housing diameter and height match the original part. Check the condition of the shaft: if it has scratches, wear or burrs, the new lip will not seal even if the size is correct. During installation, lubricate the lip, seat the seal straight and tap on the outer edge, never on the lip. If the housing has a shoulder or the shaft runs at high speed, consult us before replacing.

If you cannot find code 1114 or need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height. With those three data points we look for the equivalent in DBH or another brand we carry. A photo of the part and the housing also helps. If the original seal has no visible brand, we can still identify it by dimensions and lip type.
