The DBH 9220 is a lip-type radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. Its 40 mm shaft, 90 mm housing and 10 mm height make it a fit for gearboxes, pumps and medium-size power transmission units. MR Industrial Accessories supplies this brand and helps you match the seal to your lubricant, speed and shaft finish.

This seal follows the Kz design: a single lip with a spring, intended for shafts lubricated with oil or grease. The lip rides against the shaft while the outer diameter presses into the housing, so lubricant stays inside and dust, water or particles stay out. Shaft 40 mm, housing 90 mm, width 10 mm.

You will find this size in gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drives. Machine tools and food processing equipment also use it where lubricant must be contained and product contamination prevented. The 40x90x10 mm combination suits medium-diameter shafts with thick-wall housings.

Before installing, confirm the shaft has the right hardness and roughness, free of burrs or marks that could harm the lip. Lubricate the lip, keep the seal perpendicular to the shaft, and use an installation tool that presses on the outer diameter. If the shaft is worn, an offset lip may be the better choice. Peripheral speed, temperature and lubricant type all affect selection.

For an equivalent, send the part number 9220 along with your shaft and housing dimensions, or a photo of the old seal or the marking on its lip. With that information we can check alternatives from other brands we supply while keeping the mounting dimensions the same.
