The DBH 9212Pol radial shaft seal is a lip seal mounted between a rotating shaft and a fixed housing to retain lubricant and block the entry of dust, water or particles. Its dimensions of 68 mm shaft diameter, 85 mm housing diameter and 9.50 mm height place it in medium-sized power transmission equipment and pumps. It is a wear part: when the lip hardens or becomes marked, oil loss begins and it should be replaced.

This item is a seal from the DBH line, identified as 9212Pol, with the following dimensions: shaft diameter (d) 68 mm, housing diameter (D) 85 mm and height (h) 9.50 mm. The indicated design is Mx-R H, a radial lip configuration with a spring that ensures continuous contact on the shaft. DBH is an official brand that MR carries, so the product arrives with its factory designation and traceability.

It is used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment in general. Whenever a shaft rotates inside a housing with lubricant, the seal serves the dual purpose of containing the oil and preventing the entry of contaminants. In food, chemical or water treatment plants, this barrier is key to extending bearing life and avoiding downtime.

To install it, verify that the shaft is within tolerance and free of burrs; a scratched shaft ruins the lip within hours. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and seat the part straight, without direct hammer blows: use a tube or shim that presses only on the outer ring. If the housing has a shoulder, the seal must sit fully seated and perfectly perpendicular to the shaft.

If you cannot find the exact size, we can look for an equivalent or a neighboring size within the same family. To do so, send us the part number 9212Pol or the three dimensions (d, D and h) along with a photo of the old seal and the shaft where it works. It also helps if you tell us the equipment and the brand of the assembly, so we can cross-reference the data with the alternatives we have available.

At MR Accesorios Industriales we have worked with seals and oil seals for more than 80 years, and we can advise you on installation or selection if you tell us how your equipment is set up.
