This item is a DBH brand oil seal, designation 5518, with an Mz design. Its dimensions are 29.77 mm shaft diameter (d), 51.59 mm housing bore diameter (D) and 9.52 mm height (h). The Mz design corresponds to a configuration with a sealing lip and metal case, intended for mounting in a cylindrical housing. It is a precision component that works in direct contact with the shaft, so its correct selection and installation are key to preventing leaks and extending equipment service life.

Typical applications for this oil seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission rollers. In all these cases, the seal retains the lubricating oil or grease and prevents the entry of dust, water or particles that could damage bearings or gears. It is commonly found in equipment where the shaft rotates at moderate speeds and operating conditions demand reliable sealing.

To correctly select this oil seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. The Mz design indicates a specific lip and body geometry, so it is important to respect the mounting orientation and use the appropriate tools to avoid damaging the lip during installation. Also take into account rotation speed, temperature and lubricant type to ensure a long service life.
