With dimensions of 80 mm shaft diameter, 125 mm housing and 12 mm height, and an Lx design, it is press-fitted into the housing and works against the shaft. It is a key part in gearboxes, pumps, electric motors and transmission equipment, where it prevents leaks and protects bearings. MR Accesorios Industriales carries this brand so you have a reliable alternative for your maintenance work.

This item is a radial shaft seal from the DBH brand, identified with part number 8988. Its dimensions are 80 mm shaft diameter (d), 125 mm housing diameter (D) and 12 mm height (h). The Lx design indicates a configuration with a sealing lip and a specific profile for rotating applications. The lip, generally made of elastomer, rests on the shaft and creates a barrier against oil or grease, while the metal body secures it in the housing. It is a standard solution for sealing shafts that rotate inside a housing.

Typical applications for a seal such as the DBH 8988 include gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain transmission equipment. In all these cases, the seal prevents lubricant loss and the entry of dust, water or particles that accelerate wear on bearings and gears. It is also used in machine tools, food industry equipment and hydraulic systems, where fluid containment is critical for performance and cleanliness of the environment.

To install this seal correctly, verify that the shaft measures 80 mm and the housing 125 mm, with adequate depth for the 12 mm height. The shaft surface must be polished and free of burrs; lubricate the lip before inserting it and use an installation tube that presses on the outer edge, never on the lip. If the shaft shows wear, consider a seal with an auxiliary lip. Selection depends on speed, temperature and type of fluid; if in doubt, consult our technical team.
