The DBH 5111 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Its dimensions of 49.20 mm shaft diameter, 65.06 mm housing diameter and 12.70 mm height make it suitable for equipment with shafts of approximately 49 mm. It is press-fitted into the housing and runs against the shaft, creating a dynamic barrier that protects bearings and mechanisms. It is a frequently replaced part in industrial maintenance.

This item is a radial shaft seal from the DBH brand, identified by the code 5111. Its dimensions are: shaft diameter (d) 49.2 mm, housing diameter (D) 65.06 mm and height (h) 12.70 mm. The Mx design corresponds to a configuration with a single sealing lip and metal body, suitable for applications where axial space is limited. The lip, generally made of elastomer, rests on the shaft and keeps the lubricant inside the assembly. The outer case ensures a firm fit in the housing.

Radial shaft seals such as the DBH 5111 are used in gearboxes, pumps, electric motors, conveyor rollers and power transmission equipment. Their main function is to prevent oil or grease leaks and block the entry of dust, water or particles. In environments with chips or moisture, the sealing lip extends the service life of bearings and gears. They are also used in automotive applications and agricultural machinery.

To correctly select a seal, verify that the shaft and housing dimensions match those of the equipment. The shaft surface must be ground and free of splines, with hardness and roughness suitable to avoid damaging the lip. During assembly, lubricate the lip with the same grease or oil used in the system and use an installation tool that presses on the outer edge. Avoid striking the seal directly. If the shaft shows wear, consider a repair sleeve or an alternative size.
