The DBH 1108 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants in rotating equipment. With dimensions of 111.13 mm shaft, 158.78 mm housing and 15.37 mm height, and an A 255 design, it is used in gearboxes, pumps, electric motors and transmissions where the shaft rotates on bearings. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal for your application.

This item is a DBH 1108 radial shaft seal, identified with designation 1108 and A 255 design. Its dimensions are 111.13 mm shaft diameter (d), 158.78 mm housing diameter (D) and 15.37 mm height (h). The A 255 design corresponds to a single-lip configuration with spring, intended for rotating shafts with permanent lubrication. The elastomer and internal spring maintain contact on the shaft to contain oil or grease and stop dust and water from entering.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, reducers and power transmission equipment. In all cases it works on a shaft rotating inside a fixed housing, generally alongside a bearing or bushing. Its function is twofold: to prevent lubricant leaks to the outside and to protect the interior of the mechanism against abrasive particles, chips or moisture that shorten bearing life.

For installation, check that the shaft and housing diameters match the indicated values, that the shaft surface is polished and free of burrs, and that the housing has the proper entry chamfer so as not to damage the lip. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, with a tube or press bearing on the outer ring. If the equipment operates with high vibration or temperature, ask whether a different compound is advisable.
