The DBH 5281Sil is a radial shaft seal built to keep lubricant in and contaminants out where a shaft turns. Its sealing lip carries a spring, and the Lz designation identifies that lip-and-spring configuration. The dimensions are shaft 70 mm, housing 90 mm and height 10 mm, a size that turns up on many types of industrial machinery. MR Industrial Accessories LLC supplies this brand and can help you confirm the right seal for your equipment.

Reading the number helps when you are matching a part. The 5281Sil identifies a DBH radial shaft seal, and the three figures that follow describe the bore it fits: 70 mm shaft diameter, 90 mm housing diameter and 10 mm overall height. The Lz code tells you the lip is spring-loaded, so it stays in even contact with the shaft. This seal is one of the DBH items MR supplies, and we can talk through where it is used.

Seals in this family sit in gearboxes, pumps, electric motors, rollers and power transmission assemblies. They hold oil or grease where it belongs and keep dust, water and particles away from the bearings behind them. That makes them common in food processing, mining, petrochemical plants and general manufacturing, where a failed seal can mean a failed bearing not long after.

Selection comes down to the three dimensions plus the condition of the shaft. The surface should be polished and hard enough that the lip is not worn down prematurely. At installation, coat the lip with the same oil the equipment runs on and check that the spring sits where it should. Keep tools away from the sealing face, since a nick or a blow can ruin the seal before it ever turns.

If you need a cross to another brand, send the full part number, the exact dimensions and a photo of the old part when you can. We look for alternatives that match the shaft and housing diameters, including standard heights, so the replacement fits your equipment.
