The DBH 8240 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Its dimensions — 68 mm shaft, 80 mm housing and 8 mm height — place it in medium-sized transmission equipment and pumps. MR Accesorios Industriales sells this brand and will quote it on WhatsApp with part number 8240.

This item is a DBH radial shaft seal with designation 8240. According to its attributes, it is designed for a shaft diameter (d) of 68 mm, a housing diameter (D) of 80 mm and a height (h) of 8.00 mm. The stated design is A 062, which defines the geometry of the lip and the metal body. These three values identify it unambiguously: any replacement must match 68 x 80 x 8 mm and the same design type so that the lip seats correctly on the shaft.

Seals of this size are used in gearboxes, centrifugal pumps, electric motors and power transmission equipment where a shaft rotates inside a housing. Their function is twofold: to prevent oil or grease from migrating outward and to stop the entry of contaminants that wear down bearings and bushings. In industrial plants, it is a frequently replaced part with a relatively low cost compared with the failure it prevents.

Before mounting it, check that the shaft has no burrs or marks in the contact area and that the housing is clean and free of deformation. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and use a flat driver that presses on the outer diameter, never on the lip. If the shaft shows wear, consider a design with an auxiliary lip. Selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent, send us part number 8240 along with the shaft and housing dimensions, a photo of the old part and, if possible, the equipment brand. With that data we can look for an alternative within the DBH line or other brands we sell. It is also helpful to indicate the type of lubricant and the operating temperature to better guide the choice.
