The DBH 5123Sil is a radial shaft seal, also called an oil seal, that presses into a housing and rides against a rotating shaft. It holds lubricant in and keeps dust, water and other particles out. The size is 15 mm shaft, 28 mm housing and 6 mm height, with Lx design. MR Industrial Accessories supplies it through its seals and oil seals line for customers in the United States and Latin America.

Reading the number: 5123Sil points to the size and lip variant, while the dimensions are shaft 15.00 mm, housing 28.00 mm, width 6.00 mm. The Lx design is a single lip with a spring, meant for rotating shafts that run with lubrication. It is a drop-in replacement: the seal sits in the housing bore and the lip contacts the shaft. Before installing, inspect the shaft for burrs or wear and confirm the housing is clean and not deformed.

Typical duty covers centrifugal pumps, electric motors, gearboxes, mixers, compressors and machine tools, as well as power transmission parts such as gear cases and conveyor rollers. In every case the seal runs between a turning shaft and a fixed housing, keeping lubrication where it belongs and helping bearings and gears last.

When choosing a seal, look at shaft speed, operating temperature and the lubricant in use. The Lx design with spring fits medium speeds and low pressures. In dirty or wet conditions, consider an extra lip or a guard. At installation, lubricate the lip, slide it on with a support tube to avoid damage, and keep the spring facing the fluid side. A seal set wrong will leak early.

For a quote, send the complete part number, the shaft, housing and height dimensions, and a photo of the old seal. With that we can check equivalents within the lines we carry and tell you if Lx is not the best choice for your equipment. The goal is to keep your machinery running without a sealing part holding you up.
