When a shaft needs to keep oil or grease inside its housing and contamination out, a radial shaft seal does the job. The DBH 5141Vit is one of those seals, sized at 50 mm on the shaft, 72 mm in the bore and 10 mm tall, with an Lz design. MR Industrial Accessories supplies it through its seals and oil seals line to maintenance and purchasing teams across the United States and Latin America.

Reading the designation helps when you order. DBH is the brand, 5141Vit is the code, and the three figures that matter are d = 50 mm (shaft), D = 72 mm (housing bore) and h = 10 mm (height). The Lz design means the seal carries a main sealing lip plus a secondary dust lip on the air side. That second lip keeps grit and water away from the main lip, which is why this style shows up in dirty or washdown environments.

You will find this size in gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools, basically any rotating assembly where a shaft runs on bearings inside a lubricated housing. The seal works from two directions at once: it holds the oil or grease in, and it blocks dust, water and particles from reaching the bearing cavity.

Installation is where most seal failures start. The shaft should be clean and free of burrs or deep scoring, and the bore has to be the right diameter and in serviceable condition. Lubricate the lip before seating it, and drive the seal in with a tube or socket that contacts the outer ring, not the lip. Before choosing a replacement, check the d, D and h values, the design, and the actual speed, temperature and fluid in the application. High peripheral speed or elevated temperature means the lip and elastomer need a closer look.

For a quote, send the full code and the dimensions of the seal you are replacing. A photo of the part and the housing, or the equipment drawing, works just as well. With that information our team can match the DBH 5141Vit or suggest an alternative with the same 50 x 72 x 10 mm dimensions and the same design type. Keep in mind that equivalents are not always interchangeable: material, lip profile and dust lip vary, and each one affects how the seal performs.
