The DBH 5521 radial shaft seal is a lip seal that blocks the passage of oil or grease in equipment with a rotating shaft. It is press-fitted into the housing and its flexible lip runs on the shaft, preventing leaks and the entry of dust or water. Due to its dimensions of 35 mm shaft, 52.37 mm housing and 11.11 mm height, and its Mz design, it is a replacement part for gearboxes, pumps and electric motors. MR Accesorios Industriales sells it as an official brand.

This item is a seal from the DBH line, identified with part number 5521. Its nominal dimensions are 35 mm shaft diameter (d), 52.37 mm housing diameter (D) and 11.11 mm height (h). The Mz design corresponds to a configuration with a sealing lip and metal body, suitable for retaining lubricant and excluding contaminants under rotating conditions. It is a precision part that is press-fitted into the housing and requires a shaft with a suitable surface finish for the lip to seal correctly.

Typical applications for a seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases it serves to confine the oil or grease inside the assembly and protect bearings and gears from the ingress of particles. It is also used in equipment exposed to splashes or dusty environments, provided the lip material is compatible with the fluid and the operating temperature.

To correctly select and install this seal, verify that the shaft and housing dimensions match those of the record: 35 mm and 52.37 mm respectively. The housing must be clean, free of burrs and with the entry chamfer in good condition. Lubricate the lip before installing and avoid hitting it during installation. The 11.11 mm height defines the available axial space. If the shaft shows wear or roughness, consider a repair sleeve or consult our technical team.
