The DBH 1287 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. It features a single sealing lip with a spring, a metal case and an elastomer body, and its designation 1287 identifies the size. The dimensions are shaft 25 mm, housing 47 mm and height 5.00 mm. The Lx design is intended for moderate-speed shafts with permanent lubrication and no significant pressure differential.

You will find this seal in centrifugal pumps, electric motors, gearboxes, compressors, fans and other power transmission assemblies. It also appears in machine tools, washing systems and irrigation equipment where shafts turn in the presence of water or dust. In every case, its job is to hold oil or grease inside the housing and block outside particles from reaching the bearing.

When replacing a worn seal or building a new assembly, read the code first: 1287 gives the size, and Lx tells you it is a single-lip, spring-loaded design. Check that the shaft is within tolerance and free of burrs or marks that could cut the lip. The housing bore must be clean and its entry chamfer in good shape. Lubricate the lip before pressing the seal in, and make sure the spring faces the fluid side.

If the equipment runs with vibration or misalignment, consider a more rigid design or one with an auxiliary lip. To find an equivalent, send the full code, the shaft, housing and height measurements, and a photo of the old part if available. With that information we can search the same DBH line or other brands we supply for a match.
