With dimensions of 48 mm shaft diameter, 72 mm housing diameter and 10 mm height, and an Lz design, it is used in gear reducer boxes, pumps, electric motors and industrial equipment where reliable sealing is critical. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal of the DBH brand, identified with the part number 5145. Its dimensions are 48 mm shaft diameter (d), 72 mm housing diameter (D) and 10 mm height (h). The Lz design corresponds to a seal with a sealing lip and dust lip, designed to retain lubricant and exclude dust or dirt. The elastomer of the lip and the internal spring guarantee uniform contact on the shaft, while the metal body ensures a firm fit in the housing.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. In all cases, its function is to prevent the loss of oil or grease and to protect the bearings from the ingress of abrasive particles. It is a wear part that should be replaced when leaks, abnormal noises or shaft play are detected.

To install the seal correctly, verify that the shaft has the appropriate hardness and roughness, without burrs or marks. Lubricate the lip with the same oil or grease used in the application before inserting it. Place the seal perpendicular to the shaft and use an installation tube that rests on the outer diameter, never on the lip. If the housing shows wear, consider a repair sleeve.

We also offer technical advice to select the lip material (NBR, FKM, etc.) according to the temperature and the fluid in your equipment.
