MR Industrial Accessories LLC supplies this brand and can help you confirm the right seal for your application.

This seal belongs to the DBH line and carries the code 5477Sil. The Mz designation refers to a particular lip and casing construction within the radial shaft seal family. In service, the outer case holds the seal in the housing bore while the lip contacts the rotating shaft to retain oil or grease and block dust and moisture. It is a replacement component for assemblies that need lubricant containment and protection from outside particles.

Seals of this size are common in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. Plants in industrial, food and process environments use them on shafts near 101.6 mm that run in standard housings. Machines of older or imported origin often call for inch dimensions like these. The seal's job is to keep lubricant where it belongs and to stop abrasive particles from reaching bearings and gears.

When selecting a replacement, match the shaft diameter, housing bore and width to the mounting space. The Mz design also has to suit the lip type and material your application requires, since operating temperature, shaft speed and the fluid being sealed all affect the choice. At installation, coat the lip with lubricant, keep it away from sharp edges and check the shaft for burrs or scratches. Even a correctly sized seal can fail early if it is fitted carelessly.
