The DBH 5657 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles. With dimensions of 70 mm shaft, 89 mm housing and 12.50 mm height, and Mx design, it is a replacement part for equipment with shafts of that diameter. MR Accesorios Industriales carries it as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified with part number 5657. Its dimensions are 70 mm shaft diameter (d), 89 mm housing diameter (D) and 12.50 mm height (h). The Mx design corresponds to a specific construction configuration within the radial shaft seal category. The sealing lip runs on the shaft and the outer case fits into the housing, generally metallic, to fix the position and prevent rotation. It is a wear part that is replaced when lubricant leakage or contaminant ingress appears.

It is used in gearboxes, pumps, electric motors, rollers and transmission equipment where the shaft rotates inside a housing. It also appears in agricultural machinery, material handling equipment and process lines. Its function is critical for the life of the bearing and the lubricant: a worn seal lets grease or oil escape and allows dust to enter, which accelerates wear on bearings and gears. That is why it should be checked at every scheduled maintenance.

To install a seal, verify that the shaft has no burrs or excessive wear in the lip area, and that the housing is clean and free of deformation. The seal is inserted perpendicular, without striking the lip, using a tube or spacer that presses on the outer case. Before installing it, lubricate the lip with the same oil or grease used in the equipment. If the shaft shows a deep groove, consider an alternative size or a repair sleeve. Selection is made by the three dimensions and by the design type, not only by the part number.

If you need a seal equivalent to the 5657, the most practical approach is to send the shaft, housing and height dimensions, plus a photo or the part number engraved on the old part. With that data, a nearby size or a replacement from another brand that performs the same function can be found. Design variants can also be evaluated if the equipment runs at high speed or temperature. We do not invent dimensions: if the record does not include a data point, it is confirmed against the manufacturer's data sheet before quoting.
