The DBH 6721 oil seal is a radial seal with 75 mm shaft diameter, 113 mm housing diameter and 15 mm height, with Lz design. It is used to retain lubricant and exclude contaminants in equipment with rotating shafts, such as pumps, electric motors, gear reducers and gearboxes. Its flexible lip runs on the shaft and maintains sealing under continuous rotation. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct oil 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 designation 6721 identifies the size and construction type within the DBH line. It is a sealing component that is press-fitted into the housing and rests its lip on the shaft to contain lubricant.

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

To install this oil seal, verify 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 an oil seal with an auxiliary lip.
