Part of the DBH line of radial shaft seals carried by MR Industrial Accessories LLC, the 5111Sil is a lip seal that sits on the rotating shaft and seals against the housing bore. It holds lubricant inside the assembly and keeps dust, water and other contaminants out. With a 49.20 mm shaft, a 65.06 mm housing and a 12.70 mm height, it fits medium-sized rotating and transmission equipment.

Reading the code starts with the three figures that govern mounting: shaft 49.20 mm, housing 65.06 mm, height 12.70 mm. The 5111Sil uses the Mx design, whose flexible lip rides on the shaft while the metal case is held by interference in the bore. Those proportions describe a medium-section seal, suited to shafts where axial room is tight but the closure still has to hold.

Typical installations include gearboxes, pumps, electric motors, fan shafts and transmission assemblies where oil or grease has to stay separated from the surroundings. The same seal also turns up in machine tools and in washing equipment exposed to water or steam, as long as shaft and housing match the stated dimensions. The job is always the same: stop leakage and protect the bearing or bushing behind it.

Before pressing one in, confirm the shaft is within tolerance and free of burrs, and that the bore has the correct diameter and finish. Put lubricant on the lip, then drive on the case only, never on the lip. Where peripheral speed or temperature runs high, the lip compound should be selected for those conditions; a seal that is not seated squarely will not perform, even with correct dimensions.

For a quote on the 5111Sil, send the complete code together with the shaft, housing and height measurements, and a photo of the removed seal if you have one. With that information we can look for an equivalent, either in the same brand or in another line we supply. If the Mx geometry does not suit the application, we can point you toward a different lip configuration.

DBH seals and oil seals form part of the MR Industrial Accessories LLC catalog, alongside bearings, mounted units and housings, power transmission components, lubrication and maintenance tools.
