The DBH 1226 is a single-lip radial shaft seal with an Mx design, built to keep lubricant in and contaminants out where a shaft turns inside a housing. Its dimensions are 41 mm for the shaft, 50.90 mm for the housing bore and 6.35 mm for the width. MR Industrial Accessories supplies this seal as part of its seals and oil seals range for maintenance and repair work.

Reading the DBH 1226 designation is straightforward: the 1226 code points to a specific size in the DBH line, and the Mx design tells you it is a single lip with a spring. The three measurements you need to match are shaft 41 mm, housing 50.90 mm and width 6.35 mm. This is a standard replacement seal, so it is normally selected by those dimensions rather than by a custom drawing.

You will find this seal on rotating shafts in gearboxes, centrifugal pumps, electric motors, mixers and belt or chain drives. It also shows up in washing equipment, water pumps and agricultural machinery. In every case the job is the same: hold oil or grease on the inside and keep dust and water from entering from the outside, which helps protect bearings and gears.

Before installation, inspect the shaft for burrs or wear and make sure the housing bore is clean and free of dents. Lubricate the lip, then press the seal in with a tube of the correct diameter instead of striking it directly. Shaft runout and surface roughness both affect how long the seal lasts. If the shaft has a visible groove, consider a seal that places the lip in a different position, and our team can help you evaluate that option.

If you are looking for an equivalent, send the code 1226 or the dimensions you have. We can also review alternatives when the housing or shaft tolerances differ. Sharing diameters, width, lubricant type and operating conditions helps us give you a more accurate recommendation.
