The DBH 8146 radial shaft seal is a lip seal designed to close off the passage of oil or grease on rotating shafts and prevent the entry of dust, water or particles. Due to its size of 85 mm shaft, 105 mm housing and 13 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this brand and advises you so you can choose the right oil seal for your application.

This item is a radial shaft seal from the DBH brand, identified by the code 8146. Its nominal dimensions are 85.00 mm shaft diameter (d), 105.00 mm housing diameter (D) and 13.00 mm height (h). The Lz design corresponds to an oil seal with a sealing lip and a construction configuration specific to retaining lubricant in one direction. It is a precision component that runs supported on the shaft and housed in a machined cavity, with the lip exerting radial pressure against the shaft surface.

Typical applications for an oil seal of this size include gearboxes, reducers, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. In all cases it fulfills the function of retaining the lubricant inside the assembly and blocking the entry of external contaminants, extending the service life of bearings and gears. It is commonly found in industrial equipment where the shaft rotates at moderate speeds and the working temperature does not exceed the limits of the elastomer.

To install a radial shaft seal correctly, check that the shaft has no burrs, scratches or wear that could damage the lip. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the oil seal perpendicular to the shaft, using a tube or shim that presses on the outer diameter, never on the lip. Selection must take into account rotation speed, temperature, type of lubricant and differential pressure. If the shaft shows wear, consider an oil seal with an auxiliary lip or a repair size.

If you need an equivalent or a nearby size, the most practical thing is to send us the code 8146 or the current dimensions of the oil seal on WhatsApp. With that data we can look for alternatives in other brands or configurations within the same category. We can also guide you if the housing or shaft has tolerances outside the usual range, or if you need a version with a double lip, high-temperature-resistant material or a stainless steel spring.
