When a rotating shaft passes through a housing, the DBH 9574 radial shaft seal keeps lubricant in and contaminants out. The code identifies a lip seal built for a 26.80 mm shaft, a 38.05 mm housing bore and a 5.50 mm width, so it fits compact assemblies such as gearboxes, pumps and electric motors. Its A 244 design corresponds to a single lip with spring. MR Industrial Accessories supplies this brand and can help you confirm the selection.

Reading the code is straightforward. The 9574 number identifies the seal, while the three figures follow the usual order for this type of part: shaft 26.80 mm, housing 38.05 mm, width 5.50 mm. In other words, d equals 26.80 mm, D equals 38.05 mm and h equals 5.50 mm. The A 244 designation describes a single lip with spring, a common choice for rotating shafts. The elastomer compound resists oils and greases, and a metal reinforcement holds the seal steady inside the bore. The part protects bearings and gears by keeping lubricant where it belongs.

You will find this seal on gearboxes, centrifugal pumps, electric motors, compressors and power transmission equipment. In each case it closes the gap where the shaft exits the housing, so oil stays inside and dust, water or particles stay outside. Agricultural machinery, process equipment and hydraulic systems often use it where space is tight and moderate shaft speeds are the norm.

Installation calls for clean, burr-free surfaces on both shaft and housing. Coat the lip with the same oil or grease the equipment runs on, then press the seal in with a tube that bears on the outer diameter rather than the lip. When selecting a replacement, weigh rotation speed, operating temperature and how the elastomer behaves with the fluid in use. A worn shaft may call for a seal with an auxiliary lip. Housing tolerances should always be checked against the manufacturer's figures.

If you need a cross-reference for the DBH 9574, send the code, the shaft, housing and height dimensions, and a photo of the original seal if you have one. Our team can suggest equivalents from other brands or series that match the same dimensions and performance, and can advise on the most suitable lip design for your application.
