The DBH 8231 is a radial shaft seal with a single lip and spring, designed to keep oil or grease in and contaminants out of rotating shafts. It fits a 13.50 mm shaft, a 28.50 mm housing bore and has a 7.00 mm height. MR Industrial Accessories supplies this seal and helps you confirm it is the right choice for your equipment.

This seal uses the Lz design: a metal case with a sealing lip and a spring. The lip presses against the shaft while the case holds in the housing, creating a barrier that retains lubricant and blocks dust and water. The three key dimensions are shaft 13.50 mm, housing 28.50 mm and height 7.00 mm.

You will find the DBH 8231 in gearboxes, centrifugal pumps, electric motors, compressors and other power transmission equipment. It is also common in machine tools and food processing equipment where oil or grease must stay contained. Its compact size suits small-diameter shafts running at moderate speeds.

Before installing, check that the shaft, housing bore and height match the DBH 8231. The shaft should be clean, free of burrs and wear, and the sealing surface should have the correct roughness. Lubricate the lip and use a tool that will not damage it. Shaft runout and operating temperature affect how long the seal lasts.
