The DBH 5354Sil is a radial shaft seal built for a 55 mm shaft running in a 75 mm bore, with an overall width of 12 mm. Its Lz configuration pairs a primary sealing lip with a secondary dust lip, which is what makes it a practical choice where grit and airborne particles are part of daily operation. Gearboxes, pumps, electric motors and power transmission equipment rely on this kind of seal to hold oil or grease in place and keep contaminants out.

Reading the code helps when you are cross-referencing. The 5354Sil number belongs to the DBH seal line, and the three figures that follow in the designation describe the geometry: shaft 55 mm, housing bore 75 mm, width 12 mm. The Lz suffix tells you the lip arrangement, a sealing lip plus an exclusion lip, so the seal is aimed at service conditions where particles are present rather than at a clean, closed environment.

These seals sit in rotating assemblies wherever lubricant has to stay separated from the surrounding atmosphere. Typical locations include gear reducers, centrifugal pumps, electric motors, conveyor rollers, and belt or chain drives. In food, chemical and process plants, that extra dust lip helps keep the lubricant free of debris, which in turn protects the bearings and bushings nearby.

Correct selection comes down to three checks. Confirm the shaft diameter falls within the tolerance recommended for radial shaft seals, confirm the housing bore has the right diameter and surface finish, and confirm the 12 mm width fits the housing depth. During installation, use tools that will not nick the lip and pre-lubricate the sealing edge. Where dirt exposure is heavy, the Lz version is worth considering over a plain single-lip seal.

If you are after an equivalent, the fastest route is to send the code 5354Sil or your measured dimensions, shaft, housing and width, along with a short note on the application. From there we can look at alternatives in the same DBH line or in other brands we supply, and advise on which lip design suits your contaminant and rotation speed.
