When a rotating shaft starts weeping oil, the fix usually comes down to one wear part: the radial shaft seal. The DBH 5346 is a lip seal built for exactly that job, keeping lubricant inside the housing and keeping dust, water and particles out. Its three governing measurements are a 47.63 mm shaft, a 69.88 mm bore and a 12.70 mm width, and it uses the Lz design. MR Industrial Accessories supplies this brand within its seals and oil seals line for maintenance and replacement work.

Reading the reference is straightforward. The 5346 designation is the ordering number, while DBH identifies the brand, which is one of the brands we supply. Fit is defined by three values: d, the shaft diameter, at 47.63 mm; D, the housing bore, at 69.88 mm; and h, the height, at 12.70 mm. The Lz design is a single lip with a spring, which is the configuration used to hold oil or grease in place on a turning shaft. As long as part number 5346 is quoted, the replacement matches the original reference.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, bearings on transmission shafts and continuous process equipment. In each case the seal does two things at once: it stops lubricant from escaping and it shields the bearing from dust, water or particles. Because it is a wear part, it is normally changed when dripping, noise or shaft play shows up, or during a planned maintenance shutdown before those symptoms appear.

Before fitting, confirm the shaft at 47.63 mm, the bore at 69.88 mm and 12.70 mm of available height. The Lz design calls for a polished shaft free of burrs and a bore with a proper radius so the lip is not cut during installation. Coat the lip with lubricant, then seat the seal square to the shaft using a mounting tube that presses on the outer diameter. Where the shaft itself is worn, a repair sleeve is worth considering.
