This DBH 1309 oil seal is identified by its designation 1309 and corresponds to a radial seal with a sealing lip. According to the product page data, the housing diameter is 75 mm and the overall height is 10 mm. The A 378 design defines the lip geometry and the type of elastomer, suitable for applications with oil or grease.

Radial seals such as the DBH 1309 are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their mission is twofold: to prevent lubricant leaks and to block the entry of external particles. In food, chemical or aggregate processing plants, where there is washing or dust, this type of seal extends bearing life. It is also used in agricultural and road machinery maintenance, where periodic replacement is part of the shutdown plan.

To correctly select an oil seal, you must verify the shaft diameter, the housing diameter and the height. In this case, the 75 mm housing and the 10 mm height are firm data. The A 378 design indicates a specific profile that may require an entry chamfer and a polished shaft surface so as not to damage the lip. During assembly, lubricate the lip and use a guide sleeve to prevent the spring from coming out of its seat.
