The DBH 5656 oil seal is a single-lip radial shaft seal that mounts on the shaft and inside the housing to retain lubricant and block the entry of dust, water or particles. Because of its dimensions —63.50 mm shaft, 88.90 mm housing and 12.70 mm height— it is used in equipment with medium-section shafts, such as pumps, gearboxes and transmissions. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a DBH radial shaft seal identified with part number 5656. Its dimensions are 63.50 mm shaft diameter (d), 88.90 mm housing diameter (D) and 12.70 mm height (h). The indicated design is Mx, which corresponds to the construction configuration of the lip and the metal body. These three values define the seat: the lip runs on the shaft and the outer contour seats in the housing. If you need to confirm the Mx design nomenclature, we can check it against the manufacturer's data sheet.

Typical applications for a seal of this size appear in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a fixed housing. The function is twofold: to prevent oil or grease from escaping and to stop contaminants from entering. In environments with dust, chips or water, the seal is the first barrier, which is why it should be checked every time the assembly is taken apart.

To install it correctly, check that the shaft has no burrs or wear in the lip area and that the housing is clean and free of dents. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without tilting it. If the equipment runs at high speed or with high internal pressure, a reinforced design or an auxiliary lip may be advisable. The final selection depends on speed, temperature and fluid.

If part number 5656 is not the one you need, we can look for a nearby size or an equivalent from another brand. To do that, send us the shaft diameter, housing diameter and height you have measured, or the original equipment part number. A photo of the old seal with a caliper next to it also works. With that data we review alternatives within the DBH line and other brands we carry.
