The DBH 6278 is a single-lip radial shaft seal built for rotating shafts. Its Ls design uses a sealing lip with an internal steel spring. The size fits a shaft of 24 mm, a housing bore of 34 mm and a 4 mm height. It keeps lubricant in and dirt out of gearboxes, pumps and electric motors. This brand forms part of the industrial seals line MR Industrial Accessories supplies.

Reading the code and size together saves time at the counter. The 6278 identifies the seal; the numbers 24x34x4 mm describe shaft, housing and height in that order. The Ls configuration means a lip with spring, the common layout for this style of seal. The body is press-fitted into the housing, while the flexible lip rides against the shaft.

Where does this seal earn its place? Gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drives are typical. Process equipment, machine tools, conveyors and ventilation systems also use it. The small envelope suits tight spots that still need a proper seal. Oil or grease lubrication and moderate dust or moisture are the conditions it handles.

Selection starts with the shaft and housing measurements, then speed and temperature. The Ls design suits moderate peripheral speeds and low pressures; other duties may call for a different variant. On installation, coat the lip with the same lubricant used in the machine, press the seal in squarely and keep sharp edges away from the lip. Clean shaft and housing surfaces help the seal last.
