The DBH 6850 radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of contaminants such as dust, water or particles. With dimensions of 31.00 mm shaft, 47.00 mm housing and 7.50 mm height, and a design A 178, it is used in a wide variety of industrial equipment. MR Accesorios Industriales supplies this official brand and advises you so you can choose the correct seal for your application.

This item is a DBH 6850 radial shaft seal, identified by its designation 6850. Its main attributes are: shaft diameter (d) of 31 mm, housing diameter (D) of 47 mm and height (h) of 7.50 mm. Design A 178 corresponds to a specific construction configuration within the DBH line. These values are what define dimensional compatibility with the shaft and the housing where it is mounted. It is a sealing component that works with relative movement between the lip and the shaft surface.

Typical applications for a seal such as the DBH 6850 include gearboxes, pumps, electric motors, reducers and power transmission equipment. In these systems, the seal prevents oil or grease leaks and protects the bearings and gears from the entry of dirt. It is commonly found in industrial machinery, process equipment and vehicles. Its selection depends on the speed, temperature and type of lubricant conditions, so it is advisable to verify compatibility with the fluid and the working environment.

To correctly install this seal, verify that the shaft and housing are clean and free of burrs. Lubricate the lip with the same oil or grease it will seal before installation. Insert the seal perpendicular to the shaft, using a tube or installation tool that presses on the outer ring, never on the lip. Make sure the spring is correctly positioned. If the shaft shows wear or grooves, evaluate the need for a repair sleeve or a seal with an auxiliary lip.
