Part number 5777 belongs to the DBH line of radial shaft seals. In the size code, the shaft diameter is 34.93 mm, the housing bore is 57.15 mm and the height is 11.90 mm. The Mz design refers to a construction variant that defines the lip and metal case configuration. Always verify these values against the original part before replacement.

These seals are common in gearboxes, pumps, electric motors, drive shafts and continuous process equipment. They keep oil or grease inside the assembly and keep dust, water and particles out, which helps protect bearings and gears from premature wear. In food, chemical or water treatment plants, the lip material must be chosen according to the fluid and operating temperature.

Proper installation starts with a clean, burr-free shaft and a housing that is not deformed. Lubricate the lip with the same oil used in the equipment, then press the seal in perpendicularly to avoid damage. Shaft runout and surface roughness influence service life, so consult the permissible values from the manufacturer. If the shaft is worn, a repair sleeve or a different size may be needed.

To find an equivalent to the 5777, send the part number marked on the seal, the shaft, housing bore and height dimensions, and a photo of the assembly. With that information we can search our seals and oil seals line for a matching reference. We can also advise on lip material and spring type based on the fluid and operating temperature.
