This item is a radial shaft seal from the DBH brand, identified with part number 5433. Its dimensions are: shaft diameter (d) 12.7 mm, housing diameter (D) 25.37 mm and height (h) 9.52 mm. The Lz design corresponds to a single lip configuration with spring, suitable for single-direction rotation applications. The lip and case material are confirmed against the manufacturer's data sheet, since they are not detailed in the record.

Typical applications of this seal include water and oil pumps, low-power electric motors, gearboxes and gear cases, transmission shafts and handling equipment. Its main function is to prevent lubricant leaks and block the entry of dust, water or particles, extending the service life of bearings and bushings. It is a critical part in preventive maintenance and machinery repair.

To mount this seal correctly, verify that the shaft has the appropriate hardness and roughness, and that the housing is clean and free of burrs. Lubricate the lip before installation and make sure the spring is on the side of the fluid to be retained. If the shaft shows wear, consider using a seal with an auxiliary lip or a wear sleeve. The selection must take into account speed, temperature and type of lubricant.
