It is press-fitted into the housing and its flexible lip runs on the shaft, preventing leaks and the entry of dust or water. Because of 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 a brand.

This item is a seal from the DBH line, identified by code 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 an adequate surface finish so that the lip seals 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 fulfills the function of confining the oil or grease inside the assembly and protecting the bearings and gears from the entry 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 working temperature.

To correctly select and install this seal, check that the shaft and housing dimensions match 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 with our technical team.
