The DBH 5854 radial shaft seal is a lip seal designed to be mounted on a 28 mm shaft and seated in a 42.5 mm housing, with a total height of 8 mm. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that could damage bearings and bushings. It is a common wear part in gearboxes, pumps, electric motors and transmission equipment operating in workshops, plants and production lines.

This item is a seal from the DBH line, identified with the code 5854. Its nominal dimensions are: shaft diameter 28 mm, housing diameter 42.5 mm and height 8.00 mm. The Lz design corresponds to a single lip configuration with spring, intended for rotating shafts with permanent lubrication. The designation 5854 groups these standardized dimensions, so the seal is selected by size and not by specific application.

Radial shaft seals of this size are used in equipment where the passage of a shaft through a housing must be sealed: gearboxes and gearmotors, centrifugal and gear pumps, compressors, mixers, chain conveyors and machine tools. They also appear at the output end of electric motors and in transmission cases of agricultural or road machinery. In all cases they perform the same function: contain the oil or grease and prevent external contamination.

To mount it, verify that the shaft has the indicated size and shows no burrs, scratches or wear in the contact area. The housing must be clean and free of deformation. Lubricate the lip before inserting the seal and install it with a support tube that presses on the outer ring, never on the lip. If the shaft has play or roughness, the seal will not seal even if the size is correct. In those cases, it is advisable to evaluate a wear sleeve or a prior repair.

If you need a nearby size or an equivalent, the most practical thing is to send us the code 5854 along with the shaft, housing and height dimensions. With that data we can look for an alternative within the same DBH line or another brand we carry. We can also advise you if the Lz design is not suitable for your application and a different lip type or material is needed. The idea is that you don't buy blindly: first we confirm that the part matches what you have installed.

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals. If you already have the code at hand, send it via WhatsApp and we will provide the quote with the confirmed size. If you are not sure of the code, describe the equipment and the shaft and housing dimensions: we will help you identify it.
