The DBH 5121Sil is a radial shaft seal designed to sit in a housing and seal against a rotating shaft, keeping lubricant in and contaminants out. Its dimensions are 15 mm shaft, 35 mm housing and 10 mm height, with an Lx design. This size is common in small industrial and automotive assemblies. MR Industrial Accessories supplies it as part of its seals and oil seals range.

The code 5121Sil belongs to the DBH line and identifies both size and type. The three key measurements are: shaft 15 mm, housing 35 mm, height 10 mm. The Lx designation refers to how the lip and metal body are built, not to a dimension. Before ordering, confirm that these values match the seal you are replacing.

Seals in this size range appear in small gearboxes, pumps, electric motors, compressors, machine tools and transmission units. They are also found on wheel axles, final drives and components of agricultural and automotive machinery. Their job is always the same: retain oil or grease and block dust, water or particles that would otherwise speed up wear on bearings and gears.

Correct selection depends on more than the three dimensions. The lip type, material and direction of rotation also matter, because not every design suits the same speed or fluid. If the shaft is scored or the housing is worn, a new seal of the right size may still leak. In that case, consider a wear sleeve or repair the seat.

To request a quote for the 5121Sil, send the old seal's dimensions — shaft, housing and height — along with a photo of the part. From that information we can locate an equivalent in DBH or another brand with the same size and design, or suggest an alternative lip or material for your application. The goal is to keep your equipment running without delay.
