The DBH 8272 is a radial shaft seal that fits between a rotating shaft and a stationary housing. Its role is to keep lubricant in and contaminants out. With an 18 mm shaft, 30 mm housing, and 7 mm width, it belongs to the compact seal category often found in small pumps, electric motors, gearboxes, and light transmission systems. MR Industrial Accessories supplies this brand and can help you select the correct seal.

This seal uses an Lx design: a single lip with a spring and a metal outer case. The elastomer lip rides against the shaft, while the metal case presses into the housing bore. The dimensions are shaft 18 mm, housing 30 mm, and width 7 mm. This configuration suits rotating shafts that need a reliable barrier in tight spaces.

You will find seals of this size in small centrifugal pumps, low-power electric motors, gearboxes, compact gear cases, fan shafts, belt-driven equipment, and machine tools. They also appear in agricultural, road, and material handling machinery where dust and moisture are present. In every case, the goal is to prevent oil or grease from escaping and to keep bearings and gears free from particles.

For proper installation, check that the shaft measures 18 mm and is free of scratches or wear. The housing bore should be 30 mm and clean, with no burrs. Lubricate the lip before sliding the seal into place, and keep it perpendicular to the shaft. Avoid hitting the seal directly. If the shaft has a worn groove, a repair sleeve or a different size may be needed. Speed, temperature, and the fluid being sealed all affect selection, so consult us if you are unsure.
