The DBH 5270Sil oil seal is a single-lip radial shaft seal with spring, designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the ingress of contaminants such as dust, water or particles. With dimensions of 30 mm shaft diameter, 40 mm housing diameter and 7 mm height, and an Lz design, it is a reliable solution for demanding industrial applications.

This DBH 5270Sil oil seal has a designation that indicates its main dimensions: 30 mm shaft diameter (d), 40 mm housing diameter (D) and 7 mm height (h). The Lz design corresponds to a sealing lip with spring, which maintains constant contact on the shaft. It is made with high-resistance elastomer and a metal case that ensures a firm fit in the housing. It is an essential component for protecting bearings and mechanisms in environments with dirt or moisture.

Typical applications of this oil seal include gearboxes, pumps, electric motors, reducers and power transmission equipment. In the food, chemical or process industries, where frequent washing and exposure to external agents are common, this type of seal prevents lubricant loss and extends bearing service life. It is also used in agricultural machinery and road equipment, where dust and dirt are critical factors.

For correct installation, check that the shaft and housing are clean, free of burrs or scratches. Lubricate the oil seal lip with the same oil or grease you will use in the equipment. Insert the oil seal perpendicularly, applying uniform pressure on the metal case, never on the lip. Make sure the spring is on the lubricant side. If the shaft shows wear, consider using an oil seal with an auxiliary lip or a repair sleeve.
