The DBH 8840 radial shaft seal is a lip seal mounted on the shaft and inside the housing to retain lubricant and block the ingress of dust, water or particles. Its Lx design and dimensions of 50 mm shaft, 110 mm housing and 10 mm height make it suitable for rotating equipment where a reliable and easily replaceable barrier is needed. MR Accesorios Industriales supplies this brand and advises you to choose the correct seal for your application.

This item is a radial shaft seal from the DBH brand, identified with code 8840. Its nominal dimensions are 50.00 mm shaft diameter, 110.00 mm housing diameter and 10.00 mm height. The Lx design corresponds to a configuration with a sealing lip and a specific geometry that defines how it rests on the shaft and how it seats in the cavity. It is a standard replacement part within the category of radial seals and shaft seals, designed for rotating shafts with permanent lubrication.

Typical applications for a seal such as the DBH 8840 include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment in general. In all these cases, the seal performs two functions: preventing the leakage of oil or grease to the outside and protecting bearings or bushings from the ingress of contaminants. It is a critical part for equipment service life, so it should be replaced at any sign of leakage or visible wear.

To correctly mount this seal, verify that the shaft has no burrs or deep marks in the contact area, and that the housing is clean and free of deformation. The 10.00 mm height must match the cavity depth so the seal seats fully. When installing, lubricate the lip with the same oil or grease as the equipment and use a mounting tube that presses on the outer ring, never on the lip. If the shaft shows wear, consider a repair sleeve or an alternative size.
