The DBH 8240 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 —68 mm shaft, 80 mm housing and 8 mm height— place it in medium-sized transmission equipment and pumps. MR Accesorios Industriales carries this brand and will quote it via 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 of 68 mm diameter (d), a housing of 80 mm (D) and a height of 8.00 mm (h). The indicated design is A 062, which defines the lip and metal case geometry. These three values identify it unambiguously: any replacement must respect the 68 x 80 x 8 mm dimensions 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 bearings and bushings. In industrial plants, it is a frequently replaced part with a relatively low cost compared to the failure it prevents.

For installation, 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 nearby size or a design with an auxiliary lip. Selection depends on speed, temperature and the fluid to be retained.

If you need an equivalent or a nearby size, 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 this data we can look for an alternative within the DBH line or other brands we carry. It is also advisable to indicate the type of lubricant and the working temperature to better guide the choice.
