The DBH 8231 oil seal is a single-lip radial shaft seal that prevents oil or grease leakage and blocks dust and water from entering rotating shafts. With its dimensions of 13.50 mm shaft diameter, 28.50 mm housing diameter and 7.00 mm height, it is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this official brand and advises you so you choose the right seal for your application.

The DBH 8231 is a radial shaft seal of Lz design, with a sealing lip and metal case. Its dimensions are 13.50 mm shaft diameter (d), 28.50 mm housing diameter (D) and 7.00 mm height (h). The Lz design corresponds to a seal with a single lip and spring, suitable for rotating shafts with permanent lubrication. It is press-fitted into the housing and the lip bears on the shaft, creating a barrier against leaks and contaminants.

This type of seal is used in gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. It also appears in machine tools, food industry equipment and applications where oil or grease must be retained in a confined space. Due to its compact size, it is common on small-diameter shafts that rotate at moderate speeds and require reliable sealing.

To select the seal, verify that the shaft, housing and height dimensions match those of the DBH 8231. The shaft must be clean, free of burrs and wear, and the sealing surface must have adequate roughness. When installing it, lubricate the lip and use a tool that does not damage it. Shaft runout and operating temperature affect service life; contact us if you have any doubts.
