The DBH 1244 is a radial shaft seal built with the A 139 design. It fits a 25 mm shaft in a 45 mm housing bore, with a 7.00/8.50 mm height. Its job on rotating equipment is to hold lubricant in place and keep dust, water and other particles out of the bearing area. MR Industrial Accessories supplies it within its line of seals and oil seals.

Reading the code helps when you are matching a replacement. DBH identifies the seal type, 1244 is the item designation, and A 139 describes the design: a single lip with a metal case and an elastomeric sealing lip, meant for rotating shafts that run with permanent lubrication. The metric dimensions are listed as shaft 25 mm, housing 45 mm, width 7.00/8.50 mm. That stepped height gives a little room to work with when the housing depth is not exact.

You will find this kind of seal in gearboxes, pumps, electric motors, transmission shafts and continuous process lines. In each case it separates the lubricated side from the environment, protecting bearings and gears from contamination while keeping oil or grease where it belongs. Agricultural machinery, conveying equipment and production lines are common places to see it, since they often run in dusty or damp conditions.

Before installing, confirm that the shaft and housing measure what the seal calls for. Lubricate the lip with the same lubricant used in the system, and make sure the shaft surface is ground and free of burrs or nicks. If the equipment runs at high peripheral speed or elevated temperature, talk to our team about the lip material and the lubricant you are using, since those two factors affect how long the seal lasts.

If you are replacing an original seal, send us the code 1244 or the dimensions you measured. We compare designation, design and dimensions to suggest a compatible option, and we can also tell you whether a different height or diameter would fit the mounting space better. The goal is to keep your equipment running instead of waiting on a seal that does not match.
