The DBH 8215 is a radial shaft seal built for rotating equipment where a shaft turns inside a fixed housing. It measures 40 mm at the shaft, 54 mm at the housing and 5.00 mm in height, and it uses the Mx design. Its job is to hold lubricant in and keep contaminants out. As a wear part, it should be replaced once leakage or dirt ingress shows up. MR Industrial Accessories supplies this seal and helps you confirm it is the right one.

You can read the code in two parts. DBH identifies the brand, and 8215 is the reference for this seal. The dimensions follow the usual shaft-by-housing-by-height order: shaft 40 mm, housing 54 mm, width 5.00 mm. The Mx design refers to a sealing lip combined with a metal body, a configuration intended for rotating shafts. These figures come from the manufacturer's data sheet, so measure your shaft and housing before installation to confirm they match.

Seals like the DBH 8215 are common in gearboxes, pumps, electric motors, rollers and power transmission equipment where a shaft passes through a casing. In that position the seal does two things at once: it keeps the lubricant inside the assembly and blocks dust, water or particles from reaching the bearing or mechanism. On equipment exposed to vibration or moderate temperatures, a seal in good condition helps bearings last and keeps corrective maintenance to a minimum.

Installation calls for a clean housing and shaft, no burrs and no excessive wear. Lubricate the lip before pressing the seal in, and keep it perpendicular to the shaft, without hammer blows that could distort the metal body. If the shaft has a groove or shows wear, look at an alternative size or a repair sleeve. Speed, temperature and the fluid being retained all affect selection, so compare those conditions against the data sheet before you replace the part.

When you need a seal equivalent to the DBH 8215, send the full code along with the shaft, housing and height dimensions, plus a photo of the old seal if you have one. With that information we can search our seals and oil seals line for the matching reference. We can also tell you whether the Mx design fits your application.
