The DBH 8425/85 is a radial shaft seal built to hold oil or grease inside a housing while keeping dust and dirt out. It fits a 22 mm shaft in a 36 mm bore, with a height of 7.50/11.50 mm, and its A 090 configuration pairs a primary sealing lip with a secondary exclusion lip on a metal case with an outer coating. Gearboxes, pumps and electric motors are common homes for this size, where it protects bearings and gears from premature wear.

Reading the code is the quickest way to confirm a match: the 8425/85 block ties the bore and height combination to the A 090 construction, so the designation itself tells you what you are holding. Measured values are shaft 22 mm, housing 36 mm and overall height 7.50/11.50 mm. Keep the housing depth in mind as well, since the seal needs room to seat fully.

On the equipment side, this seal shows up in gear reducers, centrifugal pumps, electric motors, fans, compressors and machine tools, as well as general power transmission assemblies. Its job in all of them is the same: keep the lubricant where it belongs and stop water, dust and particles from reaching the bearings and gears. The auxiliary lip adds a second barrier when the surrounding environment is dirty.

Before ordering, confirm the shaft measures 22 mm and the bore 36 mm. The A 090 style is the right call when contaminants are present, because the extra lip shields the main sealing edge. During fitting, coat the lip with the same lubricant used in the machine, keep the seal square, avoid sharp blows, and check the shaft for burrs, grooves or scoring. A worn shaft can often be brought back with a repair sleeve.

If the original number no longer matches or you want to compare options, send the 8425/85 reference or the three dimensions, plus a photo of the old seal if you have one. Telling us the lubricant type and the operating conditions helps us point you to the right replacement. MR Industrial Accessories supplies the DBH line of seals and oil seals, and our team can also suggest equivalents when a different design fits the same housing.

Quotes are handled by WhatsApp or email: send the part number or the dimensions and you will get a prompt reply. If the original reference has been superseded, we can help identify the current equivalent.
