Its dimensions of 34.93 mm shaft diameter, 63.55 mm housing diameter and 12.70 mm height make it suitable for equipment where axial space is limited. MR Accesorios Industriales supplies this official brand and advises you so you can choose the right seal for your application.

This item is a DBH 5689 radial shaft seal, identified by its numeric designation and its standard dimensions: shaft diameter 34.93 mm, housing diameter 63.55 mm and height 12.70 mm. The Lz design corresponds to a single-lip configuration with spring, intended for rotating shafts lubricated with oil or grease. The DBH nomenclature refers to the brand, which MR supplies as part of its line of seals and oil seals.

Radial shaft seals such as the DBH 5689 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their function is twofold: to keep lubricant inside the assembly and to prevent the entry of dust, water or particles that accelerate wear on bearings and gears. They are common in applications where the shaft rotates at moderate speeds and the operating temperature does not exceed the limits of the elastomer.

To install a radial shaft seal, check that the shaft diameter and housing match the indicated dimensions. The lip must be lubricated before inserting the shaft, and it is advisable to use an installation tool to avoid damaging the sealing edge. Check that there are no burrs or scratches on the shaft, since a rough surface accelerates failure. The 12.70 mm height defines the space required in the housing.
