This item is a radial shaft seal from the DBH line, identified with the code 9921Vit. Its standard dimensions are 105 mm shaft diameter, 130 mm housing diameter and 12.00 mm height. The LMx-R H design corresponds to a seal with a sealing lip and a specific configuration for retaining oil or grease on rotating shafts. The commercial designation makes it easy to locate quickly in catalogs and spare parts lists.

Radial shaft seals of this size are used in applications where transmission shafts must be sealed, such as gearboxes, centrifugal pumps, electric motors, rollers and process equipment. They also appear in agricultural and industrial machinery operating with dust, water or chips present. The main function is to keep lubricant inside the assembly and protect the bearings from external contamination.

To correctly select a seal, you must verify the shaft diameter, the housing diameter and the available height. The shaft surface must be ground and free of splines or burrs in the contact area; it is advisable to lubricate the lip before installation and use a tool that prevents damaging it. Shaft eccentricity and runout also affect the service life of the seal. If the equipment operates at high speed or temperature, the lip and spring material must be evaluated.
