The DBH 6821 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering rotating equipment. Its dimensions of 55.40 mm shaft, 76.15 mm housing and 12.50 mm height make it a replacement part for specific assemblies. MR Accesorios Industriales carries this official brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified by the code 6821. Its dimensions are 55.40 mm shaft diameter, 76.15 mm housing diameter and 12.50 mm height. The Ms design corresponds to a configuration with a sealing lip and metal body, intended to retain oil or grease on rotating shafts. It is a precision part that works in direct contact with the shaft and the housing, so its tolerances and material affect the performance of the assembly.

Radial shaft seals such as the DBH 6821 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is twofold: keep the lubricant inside the mechanism and block dust, water or particles that could accelerate wear. In industrial plants, factories and machinery maintenance, this type of seal is a critical consumable that should be replaced when a leak or abnormal noise appears.

To select and install a seal, you must verify that the shaft and housing diameters match those of the seal, and that the height is compatible with the cavity. The Ms design defines the lip profile and the type of case, so do not replace it with another design without consulting us. During installation, lubricate the lip, avoid hitting it and make sure the shaft has no burrs or wear that could damage the seal.

If you need a seal equivalent to the 6821 or a nearby size, the most practical thing is to send us the full code, the shaft, housing and height dimensions, and a photo or sample of the old seal. With that data we can look for alternatives within the same brand or other lines we carry. We can also advise you if the assembly accepts a slightly different height or diameter.
