The DBH 5123Pol is a radial shaft seal that sits in a housing bore and works against a rotating shaft, holding lubricant in and keeping contaminants out. Its metric designation gives a 15 mm shaft, a 28 mm housing bore and a 6.00 mm height, with Lx design. Maintenance teams commonly pull this seal when rebuilding pumps, electric motors and gear reducers, and MR Industrial Accessories LLC supplies it through its seals and oil seals line.

Reading the code helps you match the part quickly. The 5123 series covers seals built to standard metric dimensions, DBH 5123Pol is the commercial designation, and the numbers that follow describe the fit: shaft 15 mm, housing 28 mm, height 6.00 mm. Lx refers to the design, a sealing lip combined with a metal case. That construction creates a barrier that resists oil or grease escape and blocks dust from reaching the bearing or gear cavity.

You will find this seal in small centrifugal pumps, low-power electric motors, speed reducers, gearboxes and transmission equipment. It also appears in machine tools, material handling units and hydraulic systems where a shaft turns inside a stationary housing. In each case the job is the same: retain the lubricant inside the assembly and stop outside elements such as dust, water or metal particles from getting in.

Before mounting, confirm that the shaft and housing bore match the stated figures. Fit the seal with the lip pointing toward the fluid being retained and the metal face toward the outside. Lubricating the lip beforehand and pressing it in with a proper installation tool helps avoid lip damage. Lip compound selection, whether NBR, FKM or another material, follows the operating temperature and the fluid involved, so check the manufacturer's product page for specific applications.
