The DBH 6738 radial shaft seal is a lip seal that is fitted into the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With a 110 mm shaft, a 130 mm housing bore and a 13 mm height, and Mx design, it is used in gearboxes, pumps, electric motors and transmission equipment that run on shafts of that diameter. MR Accesorios Industriales carries it as an official brand.

This item is a radial shaft seal from the DBH line, identified by the code 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 is a single-lip configuration with a spring, intended for rotating shafts with permanent lubrication. The elastomeric lip bears on the shaft and the spring maintains contact pressure; the outer body is an interference fit 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-driven transmission equipment. In all cases it serves to retain oil or grease inside the assembly and to exclude external contaminants. It is also found in older or imported machines where the original seal is no longer easy to source 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 have the exact diameter of 130.00 mm. Lubricate the lip before inserting the seal and do it with a flat tool to avoid damaging it. The 13.00 mm height must match the housing depth. If the shaft shows a worn track, consider a seal with the lip in a different position or a repair sleeve.

If you need a nearby size or an equivalent from another brand, send us the code 6738 together with the shaft, housing and height dimensions. You can also send a photo of the old seal or of the housing with a caliper. With that data we verify the exact size or a compatible alternative in the same category. Do not substitute by approximation without confirming the lip design and the elastomer type, because that affects the service life of the seal.
