The DBH 5459 radial shaft seal is a single-lip radial seal with spring, designed for rotating shafts. Its function is to retain lubricant inside the housing and prevent the entry of dust, water or contaminating particles. It is press-fitted into the housing and runs on the shaft with an oil film that ensures sealing and low friction. It is a key part in gearboxes, pumps, electric motors and industrial equipment operating with continuous rotary motion.

This DBH 5459 seal has a shaft diameter of 70 mm, a housing diameter of 90 mm and a height of 13 mm. Its Lz design corresponds to a single lip with steel spring, which ensures uniform pressure on the shaft and compensates for small misalignments. The outer body is made of elastomer, suitable for retaining industrial oils and greases under normal operating conditions. The 5459 designation identifies the exact size and profile type.

It is used in equipment with rotating shafts where lubricant leaks must be prevented and bearings protected. It is common in gearboxes, centrifugal pumps, electric motors, mixers and conveyors. It is also used in agricultural machinery and process equipment. Seal selection depends on shaft speed, working temperature and lubricant type. For applications with heavy dirt or water, it is recommended to evaluate a design with an auxiliary lip or dust guard.

During mounting, verify that the shaft has no burrs or marks that could damage the lip. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Insert the seal perpendicular to the housing, using a support tube that presses on the outer diameter, never on the lip. If the housing has a chamfer, this will ease insertion. Shaft runout must not exceed the permissible values for radial shaft seals. If in doubt, consult our technical team.
