The DBH 5312 is a radial shaft seal built to keep lubricant in and contaminants out of rotating equipment. Its designation gives the three critical dimensions: 25 mm shaft, 42 mm housing and 6 mm width. The Lx design combines a flexible sealing lip with a metal outer case, so it presses into the housing and rides against the shaft. MR Industrial Accessories supplies this seal as part of its seals and oil seals range for maintenance and replacement work.
When you read the code, the numbers tell you the fit: shaft 25 mm, housing 42 mm, width 6.00 mm. The Lx configuration means a single lip with a metal case, intended to be press-fitted into a housing bore and seal against a rotating shaft. These three measurements must match your application exactly; any mismatch in shaft or bore will cause leaks or poor seating.
This seal appears in gearboxes, pumps, electric motors, reducers, rollers and transmissions. It is a wear item, so it is replaced during scheduled maintenance or as soon as lubricant starts to escape. In repairs, it restores the original sealing of the assembly. Because it protects bearings and internal parts from dust, water and particles, replacing it on time helps avoid larger damage.
Before installing, inspect the shaft surface where the lip will run. Burrs, scratches or a pronounced groove will shorten seal life. Lubricate the lip and the shaft, then press the seal in perpendicular to the housing using a proper driver, without hitting the lip. If the shaft is worn, consider a different size or a seal with the lip positioned at another point.
If you need an equivalent, send the DBH 5312 part number or the current dimensions: shaft, housing and width. With that information we can search for an alternative within the DBH line or other brands we supply. We can also advise you if your housing or shaft has unusual tolerances, so you get a reliable option without delaying maintenance.
