The DBH 9020 seal is a radial shaft seal with a 190 mm shaft diameter, 220 mm housing diameter and 16 mm height, in the Lx design. It is used to retain lubricant and block the entry of dust, water or particles in rotating equipment. It is a common replacement part in pumps, gearboxes, electric motors and process machinery, where the shaft rotates inside a fixed housing and a reliable barrier is needed at the leak point.

This item is a DBH radial shaft seal with the dimensions indicated in its designation: 190 mm shaft, 220 mm housing and 16 mm height. The Lx design corresponds to a single-lip configuration with a spring, intended for rotating shafts with lubrication. DBH is a brand that MR carries, so the product arrives with its identification and origin traceability. If you need to confirm the exact design, it is verified against the manufacturer's data sheet.

Typical applications for a seal of this size are in transmission and process equipment: gearboxes, centrifugal pumps, electric motors, mixers, conveyors and machine tools. In all cases it performs the same function: keeping oil or grease inside the assembly and preventing contaminants from entering from the outside. It is also used as a closure in bearings and housings that work in dusty or humid environments.

For proper installation, check that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. Lubricate the lip before inserting the seal and press it in with a tube of the appropriate diameter, never with direct blows on the seal. Selection depends on shaft speed, working temperature and the type of lubricant; if the equipment operates with heavy vibration or pressure, a reinforced design should be evaluated.
