The DBH 1287 is a lip seal with a metal case and elastomer, identified by its designation 1287. Its dimensions are 25 mm shaft diameter (d), 47 mm housing diameter (D) and 5.00 mm height (h). The Lx design corresponds to a single sealing lip with a spring, intended for rotating shafts with lubrication and without high differential pressure. The manufacturer's nomenclature makes it quick to locate when replacing a worn seal or assembling new equipment.

Typical applications for this oil seal include centrifugal pumps, electric motors, gearboxes, compressors, fans and power transmission equipment. In all cases it fulfills the function of confining the lubricant inside the assembly and preventing contaminants from entering from the outside. It is also used in machine tools, washing equipment and irrigation systems where there are rotating shafts with the presence of water or dust.

To select and install an oil seal such as the DBH 1287, take into account that the shaft must be within the recommended tolerance, without burrs or marks that could damage the lip, and that the housing must be clean and have the entry chamfer in good condition. Lubricate the lip before installing and verify that the spring is on the side of the fluid to be retained. If the equipment operates with a lot of vibration or misalignment, it is advisable to evaluate a design with greater rigidity or an auxiliary lip.
