The DBH 8764/85 oil seal is a single-lip radial shaft seal that closes off the passage of oil or grease between a rotating shaft and its housing. Because of its dimensions — 25 mm shaft, 40 mm housing and 8 mm height — it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this brand and will quote it to you on WhatsApp using the exact code.

This item is a DBH radial shaft seal with the designation 8764/85, with the following dimensions: shaft diameter 25 mm, housing diameter 40 mm and height 8.00 mm. The indicated design is Lx, which corresponds to a single sealing lip with a metal body. The 8764/85 series covers this specific size within the DBH catalogue.

Typical applications for a 25 x 40 x 8 mm oil seal are input and output shafts of gearboxes, centrifugal pumps, low- and medium-power electric motors, and transmission equipment. It is also found in machine tools, compressors and lubrication systems where oil or grease must be retained and dust ingress prevented. In all cases, it is advisable to verify the shaft surface speed and the operating temperature before choosing the lip compound.

For installation, check that the shaft has no burrs or marks that could damage the lip, lubricate the seal with the same grease or oil used in the equipment, and seat the seal perpendicular to the shaft. The housing must be clean and free of old sealant residue. If the shaft shows wear, consider a neighbouring size or a seal with an auxiliary lip. The final selection depends on pressure, speed and the type of fluid.

If you need an equivalent or a close size, send us the code 8764/85 together with the shaft, housing and height dimensions, and the type of fluid. With that data we search the DBH catalogue and the other lines we carry. We can also check whether there is a variant with a double lip or a different material. The more complete the equipment information, the more accurate the proposal.
