A lip seal for rotating shafts, the DBH 5634Sil keeps lubricant where it belongs and keeps dust, water and other contaminants out of the housing. Its size is given as shaft 30 mm, housing 45 mm and height 8 mm, and the Mz design covers a sealing lip combined with a metal case. Maintenance teams keep this seal on hand as a wear item for scheduled rebuilds, and MR Industrial Accessories supplies the brand and helps match it to the equipment.

The code 5634Sil belongs to the DBH line of radial shaft seals. Reading the numbers is straightforward: 30 mm is the shaft diameter the lip rides on, 45 mm is the housing bore, and 8 mm is the overall height. The Mz designation describes the construction, a lip with a metal case, which suits rotating shafts. The elastomer lip presses against the shaft to hold oil or grease in, while the outside diameter sits in the housing bore. Because the lip wears over time, the seal is normally changed during planned maintenance rather than run to failure.

You will find this seal in gearboxes, pumps, electric motors, drive shafts and process machinery, wherever a shaft turns inside a lubricated housing that must stay separated from the surrounding environment. It also works in spots with moderate dust or splash exposure, as long as the lip material tolerates the fluid and the operating temperature. Food, chemical and materials handling plants are common places to run into it.

Installation calls for a few checks. The shaft surface should be free of burrs, nicks or scratches that could cut the lip, the lip itself gets a light coat of the same oil or grease used in the application, and the seal goes in square to the shaft. When choosing a seal, speed, temperature, lubricant and differential pressure all matter. Mz is a manufacturer reference tied to particular operating conditions, so if anything is unclear, send us your equipment details and we will review it. Avoid forcing the seal or tapping it in at an angle.
