The DBH 1098 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions — 88.90 mm shaft diameter, 122.98 mm housing diameter and 22.96 mm height — correspond to a specific application that should be verified before installation. It is used in gearboxes, pumps, electric motors and power transmission equipment where reliable sealing prevents leaks and premature bearing wear. MR Accesorios Industriales carries this brand and advises you so you choose the right seal.

This item is a radial shaft seal from the DBH brand, identified by part number 1098. Its dimensions are: shaft diameter d 88.9 mm, housing diameter D 122.98 mm and height h 22.96 mm. The A 077 design defines the lip geometry and the type of case, intended for applications with rotation in a single direction and oil or grease lubrication. It is a direct replacement part: if the original seal matches these three dimensions, this model fits without modifications.

Typical applications for a seal of this size include industrial gearboxes, centrifugal pumps, large electric motors, conveyor rollers and belt or chain drive equipment. In all cases, the function is twofold: keep the lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear. It is also used on mixer, fan and compressor shafts where the seal must withstand moderate peripheral speeds.

To install a radial shaft seal, 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 with the same grease or oil used in the equipment before inserting it, and do so with a flat driver that presses on the outer diameter, never on the lip. The 22.96 mm height should sit flush or slightly recessed according to the housing design. If the shaft shows wear, consider a repair sleeve or an alternative size.

If you need an equivalent seal or a nearby size, the most practical approach is to send us part number 1098 or the current dimensions of your shaft and housing. With that data we can look for an alternative within the DBH line or from other brands we carry, always respecting tolerances and lip type. We can also guide you if the original seal has a different designation but matches the main dimensions. The idea is that you don't have equipment down because of a sealing part.
