The DBH 5316Sil is a radial shaft seal built for rotating equipment, where its job is to hold lubricant in and keep dust and water out. Because it carries both a sealing lip and a dust lip, the Lx configuration suits areas with a moderate amount of dirt. The seal presses into a cylindrical housing bore and rides on a shaft held to controlled tolerances. MR Industrial Accessories supplies this brand and can help you match the size to your application.

The part belongs to the DBH line and is designated 5316Sil. Reading the size is straightforward: shaft 30 mm, housing bore 42 mm, width 7.00 mm. The Lx suffix tells you the lip arrangement is a primary sealing lip paired with a secondary exclusion lip, so the seal both retains lubricant and pushes contaminants away from the sealing edge. Since the number and the three dimensions follow the manufacturer's designation, you can use them directly when cross-referencing a replacement.

Seals of this type turn up in gearboxes, pumps, electric motors, transmission shafts and process equipment. In each case the goal is the same: keep the lubricant where it belongs and shield bearings or bushings from incoming particles. Treat it as a wear item. A leak, a streak of grease or unusual noise around the sealing area is a signal to inspect the lip and the shaft surface before you install anything new.

Before fitting the seal, confirm the housing bore diameter and depth, and check the shaft for burrs, deep scratches or a worn sealing surface. Coat the lip with the same oil or grease the equipment runs, then press the seal in with a tool that contacts the outer ring only, never the lip. A damaged shaft will defeat a new seal, so repair or replace it first if the surface is compromised.

To quote an equivalent, send the complete part number, the shaft, housing and width dimensions, and a photo of the part. With that information we can search the radial shaft seal category for alternatives that respect the same design and lip type. We can also tell you whether the space allows a different width, or whether a dust lip design is the better choice.
