The DBH 6881 oil seal is a radial shaft seal that keeps lubricant in and contaminants out of gearboxes, pumps, and motors. With an Lx design and dimensions of 24.50 mm shaft, 47.00 mm housing, and 7.00 mm height, it fits equipment where axial space is tight but reliable sealing is required in continuous duty.

This seal belongs to the DBH line and carries part number 6881. Its three standard dimensions are 24.50 mm for the shaft, 47.00 mm for the housing bore, and 7.00 mm for the overall height. The Lx designation indicates a single lip with a spring, intended for rotating shafts under permanent lubrication. As a DBH product supplied by MR, it preserves the original geometry and material.

Seals in this size range are common on input and output shafts of gearboxes, centrifugal pumps, electric motors, compressors, and transmission equipment. They also appear in machine tools, conveyors, and hydraulic systems where oil must be kept separate from the environment. Because it is a wear part, replace it at the first sign of leakage or when the lip becomes hard, cut, or loses elasticity.

During installation, check that the shaft is free of burrs and deep marks, lubricate the lip with the same oil used in the equipment, and seat the seal perpendicular to the shaft. Selection depends on the three dimensions—shaft, housing, and height—as well as on speed, temperature, and the fluid being sealed. If the shaft is worn, a seal with a taller lip may be considered, always after confirming the manufacturer's data sheet.

For an equivalent, send part number 6881 along with the shaft and housing dimensions. A photo of the old seal or the assembly drawing also helps. The team cross-references the designation against the manufacturer's data sheet to propose the option that best fits without compromising sealing or equipment service life.
