The DBH 8241 is a radial shaft seal, the type of lip seal that keeps oil or grease on one side of a rotating shaft and blocks dust and water from the other. It fits a 24 mm shaft in a 37 mm bore, with a height of 5.50/7.00 mm, and its design A 058 covers the lip profile and case geometry used for press-fit installation in a rigid housing.

Reading the code helps when you are matching a seal to a drawing or an old part. The 8241 designation identifies this item in the DBH line, and design A 058 describes how the lip and the metal case are formed. The dimensional sequence runs shaft (d) 24 mm, housing (D) 37 mm and height (h) 5.50/7.00 mm. The two height figures mean the sealing lip stands proud of the case: once pressed in, the case holds in the bore while the lip rides on the shaft.

Seals in this size range turn up on small electric motors, gearboxes, centrifugal pumps, compressors, reducers and machine tools, as well as on agricultural implements and power transmission equipment where bearings or bushings need their lubricant kept in place. The job is always the same: no lubricant escaping to the outside, no contaminants working their way in.

Installation is straightforward if the bore and shaft are prepared first. Look for burrs or wear on the shaft and make sure the housing is clean and not deformed. Press the seal in with the lip facing the lubricant side, using a tube or socket that bears on the outer case rather than the lip, and coat the lip with the same oil or grease the equipment runs on before it goes in. A shaft with a deep groove under the old lip is worth addressing, since a new seal may not seat cleanly on a worn track.

If you are sourcing a replacement, send part number 8241 together with the shaft, housing and height dimensions, and a photo of the old seal if you have one. From there we can check alternatives in the DBH line or in other brands we carry, and advise whether a single-height seal suits the housing or whether the 5.50/7.00 mm double height should be kept.
