Its flexible lip runs on the shaft and maintains sealing under continuous rotation. MR Accesorios Industriales sells this brand and advises you on choosing the right seal for your application.

This item is a DBH 6721 radial shaft seal, with dimensions of 75 mm shaft diameter (d), 113 mm housing diameter (D) and 15.00 mm height (h). The Lz design corresponds to a configuration with a sealing lip and spring, intended for rotating shafts. The 6721 designation identifies the size and construction type within the DBH line. It is a sealing component that is press-fit into the housing and rests its lip on the shaft to contain the lubricant.

Typical applications for a seal such as the DBH 6721 include centrifugal pumps, electric motors, gearboxes, conveyor rollers and power transmission equipment. In all cases, the function is twofold: prevent oil or grease leaks to the outside and block the ingress of dust, water or particles that accelerate wear on bearings and gears. It is also used in agricultural and road machinery and industrial equipment in general, where reliable sealing extends the service life of the assembly.

To mount this seal, check that the shaft has the 75 mm dimension and the housing the indicated 113 mm, with the tolerances and surface finish suitable for radial seals. The 15.00 mm height must match the housing depth. During installation, lubricate the lip, use a mounting tool that does not damage the seal and make sure the spring is correctly positioned. If the shaft shows wear or grooves, consider a repair sleeve or a seal with an auxiliary lip.
