The DBH 6738 radial shaft seal is a lip seal that is mounted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With 110 mm shaft, 130 mm housing bore and 13 mm height, and Mx design, it is used in gearboxes, pumps, electric motors and transmission equipment that work with shafts of that diameter. MR Accesorios Industriales sells it.

This item is a radial shaft seal from the DBH line, identified by part number 6738. Its dimensions are 110.00 mm shaft diameter (d), 130.00 mm housing bore diameter (D) and 13.00 mm height (h). The Mx design corresponds to a single-lip configuration with a spring, intended for rotating shafts with permanent lubrication. The elastomer lip rests on the shaft and the spring maintains contact pressure; the outer body fits by interference in the housing to prevent leakage around the periphery.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, large electric motors, rollers and belt or chain transmission equipment. In all cases it fulfills the function of retaining the oil or grease inside the assembly and excluding external contaminants. It is also found in old or imported machines where the original seal is no longer easy to obtain and an equivalent size is being sought.

To select and install it correctly, check that the shaft diameter is within the recommended tolerance and that the contact surface has no scratches or wear. The housing must be clean, free of burrs and with the exact diameter of 130.00 mm. Lubricate the lip before inserting the seal and do it with a flat tool so as not to damage it. The 13.00 mm height must match the depth of the housing. If the shaft has a worn track, consider a seal with the lip in a different position or a repair sleeve.

To quote part number 6738, send us the shaft, housing and height dimensions. You can also send a photo of the old seal or the housing with a caliper. With that data we verify the exact size in the same category. Do not replace by approximation without confirming the lip design and the type of elastomer, because that affects the service life of the seal.
