A single-lip radial shaft seal, the DBH 1154Vit is built for rotating shafts of 25 mm. Because its height runs from 5.00 to 11.00 mm, the lip stands out of the bore and locates against a shoulder, which is what you want when the housing is stepped. Gearboxes, pumps and electric motors rely on this kind of seal to hold lubricant in and keep dust and water out, protecting the bearings behind it. MR Industrial Accessories supplies this brand.

The seal carries the A 374 design and the designation 1154Vit. On the drawing, shaft 25 mm, housing 45 mm, width 5.00/11.00 mm. That split height is the detail to note: part of the profile sits proud of the cavity, so the bore needs a shoulder to register against. High-resistance elastomer forms the body, and a metal spring keeps the lip pressed evenly on the shaft.

Anywhere a shaft turns and lubricant has to stay put while contaminants stay out, this profile fits. You will find it in gearboxes, centrifugal pumps, electric motors, spindles and transmission equipment. Stepped housings with little axial room are where the variable height pays off, and the same holds for agricultural and industrial machinery working in dust or damp conditions.

Matching the seal to the application starts with the two diameters: confirm the shaft and the bore agree with the figures above. The shaft surface also matters, since suitable hardness and roughness keep the lip from wearing out early. At installation, coat the lip with a grease it can tolerate and press it in with a tool that will not cut or distort the seal. The 5.00/11.00 mm height only seats correctly when the housing has the shoulder that receives the protruding section.

If you are working from a drawing rather than a part number, send the dimensions 25x45x5/11 and we will take it from there. We supply DBH oil seals and can also check other brands for a close variant when the exact reference is not the right fit for your equipment.
