For rotating shafts, the DBH 5808 radial shaft seal serves as a barrier: it holds lubricant within the housing while blocking dust, water and other particles from getting in. The designation points to three measurements you can check against your equipment: shaft 55 mm, housing 72 mm, height 12.00 mm. Gearboxes, pumps, motors and similar machinery commonly use this type of seal. MR Industrial Accessories supplies the DBH line and can help you confirm whether this reference fits your assembly.

The code 5808 belongs to the DBH brand of radial shaft seals. Reading the size is straightforward: 55 mm is the shaft diameter (d), 72 mm is the housing bore (D), and 12.00 mm is the height (h). The Mz designation describes a construction with a sealing lip and spring, intended for rotating shafts that run with lubrication. For the exact lip and elastomer compound, the manufacturer's data sheet is checked when you send your inquiry.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors and power transmission assemblies. Its job in all of them is the same: keep bearings and gears protected from outside contamination and stop oil or grease from escaping. Because it is a wear part, plan to replace it during preventive maintenance or as soon as you notice lubricant leaking.

Installation depends on matching the bore and shaft. Confirm the shaft measures 55 mm and the housing 72 mm before fitting. The shaft surface should be smooth, with no burrs, scratches or heavy wear, since a rough finish will shorten lip life. Apply lubricant to the lip, then press the seal in squarely, perpendicular to the shaft, without hitting the lip directly. The 12.00 mm height sits flush or slightly recessed, depending on how the housing is machined.

If you need a cross-reference for the 5808, send the code or your measured dimensions by WhatsApp or email. The team can search for equivalents in other brands or configurations within the same radial seal category, and will tell you whether the Mz design suits your equipment or whether another lip style or material makes more sense for your operating conditions.

MR Industrial Accessories carries the DBH brand within its seals and oil seals range. To request a quote for the 5808, message the code and the team replies promptly. If you only have the shaft and housing measurements, they can also help you identify the right part.
