The DBH 6558Pol is a radial shaft seal that keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching the bearing. It fits a 90 mm shaft in a 110 mm housing bore with a 15 mm width, and it uses the Lx-Hel design. You will find this size in gearboxes, pumps, motors and similar rotating equipment. MR supplies this brand and can help you confirm the right seal for the job.

The reference to work with is 6558Pol from DBH. The three dimensions to check are shaft 90 mm, housing 110 mm and width 15.00 mm. The Lx-Hel build pairs an auxiliary lip with a return spiral, a layout meant for rotating service where the spiral helps push lubricant back toward the housing interior. The sealing lip rides on the shaft while the outer case holds in the bore. This makes it a routine replacement item in maintenance work.

You will typically see this seal in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment. In each case it keeps oil or grease contained and shields the bearings from outside contamination. A 90 x 110 x 15 mm seal is a mid-size part, so it shows up in medium-sized machines. Where dirt or water is heavy, confirm that the Lx-Hel configuration matches the working conditions before ordering.

Installation calls for a clean shaft free of burrs and marks, plus a housing machined to the correct tolerance. Put lubricant on the lip before pressing it in, and keep the seal square so it is not struck or deformed. Speed, temperature and the lubricant in use all affect selection. If the old seal let go, inspect the shaft surface and the bore as well, since a worn shaft will shorten the life of the new seal.

If you need a cross-reference, send the code 6558Pol or the size 90 x 110 x 15 mm. Should the Lx-Hel design not fit your application, alternatives can be reviewed. MR works with several brands and bases recommendations on how the equipment actually runs, so the part is confirmed before you commit to it.
