Its function is to retain lubricant inside the housing and prevent the ingress of contaminants such as dust, water or particles.

This item is a radial shaft seal from the DBH brand, identified with part number 8421Vit. Its dimensions are 110 mm for the shaft diameter (d), 130 mm for the housing diameter (D) and 13.00 mm height (h). The Lx-R design corresponds to a configuration with a sealing lip and a spring that ensures constant contact on the shaft. These dimensions allow replacing worn seals in equipment that uses this specific combination.

Radial shaft seals such as the DBH 8421Vit are used in gearboxes, pumps, electric motors, compressors and transmission systems. Their typical application is on shafts that rotate inside a fixed housing, where oil or grease must be contained and the internal bearings protected. They are also used in process equipment, agricultural machinery and industrial installations that operate with dust or moisture present.

To install this seal correctly, check that the shaft and housing are clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Installation must be perpendicular to the shaft, without striking the sealing lip. It is important that the spring remains on the side of the fluid to be retained. If the shaft shows wear, consider a repair or the use of a seal with an auxiliary lip.
