The DBH 8330/85 seal is a single-lip radial seal that mounts on a 19 mm shaft and closes against a 35 mm housing, with 8 mm height. Its function is to retain lubricant inside the assembly and stop dust, water or particles from entering. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies it as an official brand and ships nationwide.

The DBH 8330/85 is an Lx design seal: sealing lip with spring and outer metal body, designed for rotating shafts. Its dimensions are 19.00 mm shaft diameter (d), 35.00 mm housing diameter (D) and 8.00 mm height (h). The lip runs on the shaft with controlled interference, while the outer diameter is press-fitted into the housing. This combination ensures dynamic sealing and prevents axial displacement of the seal.

Typical applications for this seal appear in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. It is also found in chain or belt transmission equipment, where it protects bearings from dust and moisture. In all these cases, the 8330/85 seal performs the dual function of containing oil or grease and acting as a barrier against external contaminants.

To install it, verify that the shaft has adequate hardness and surface finish, and that it has no burrs or marks that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it. The housing must be clean and free of impacts. When replacing a seal, always compare the three dimensions: shaft diameter, housing diameter and height. If the original design is Lx, keep that configuration unless the equipment manufacturer indicates otherwise.
