The DBH 9229 is a single-lip radial shaft seal that keeps lubricant in and contaminants out on rotating shafts. It is identified by the code 9229 and built to the Kz design, a lip profile with a spring that maintains steady contact against the shaft. Shaft 40 mm, housing 72 mm, height 11.50 mm. This seal is a common replacement item in gearboxes, pumps and transmission equipment, and MR Industrial Accessories supplies it and helps you confirm the right choice for your machine.

Reading the code and dimensions: the 9229 designation identifies this radial shaft seal, and the three measurements that matter are the 40 mm shaft diameter (d), the 72 mm housing diameter (D) and the 11.50 mm height (h). The Kz design indicates a lip configuration with a spring for continuous shaft contact. The seal is press-fitted into the housing and works with rotary motion. Before installation, check these dimensions against your housing and shaft.

Where it is used: oil seals such as the DBH 9229 appear in gearboxes, reducers, centrifugal pumps, electric motors and power transmission equipment. In those assemblies they hold oil or grease in place and keep dust, water and particles away from the bearings. Fan, mixer and conveyor shafts are other typical locations. If a rotating shaft needs to contain lubricant, this type of seal is the standard answer.

Selection and installation notes: rotation speed, working temperature and lubricant type all influence seal choice. Lubricate the lip before assembly, and make sure the shaft is clean and free of burrs or marks. The shaft surface should have the right hardness and roughness for seal life. Press on the outer edge with a suitable tool so the lip is not damaged. If the housing is worn, a repair sleeve is an option.

Finding an equivalent: if you need an alternative to the DBH 9229, send the full code, the shaft, housing and height dimensions, and a photo of the part if you have one. With that information we can look for options in other brands or series that do the same job. We can also tell you whether the Kz design suits your application or whether a different lip type or material would be better. Do not guess at dimensions: a difference of tenths can cause leaks or a forced installation.
