The DBH 9217 is a radial shaft seal from the DBH line, built to fit a 25 mm shaft, a 47 mm housing bore, and a 7 mm width. Its job is to hold lubricant in place while keeping dust, water, and other contaminants out of the assembly, protecting bearings and gears from premature wear. As a wear item, it should be replaced whenever the equipment is opened up or at the first sign of leakage. MR Industrial Accessories LLC supplies this seal as part of its seals and oil seals range.

This seal follows the A 101 design, which means a single lip with a spring. The dimensions are: shaft 25 mm, housing 47 mm, width 7.00 mm. The 9217 code identifies this specific size combination within the DBH line. Before installation, double-check that the shaft and housing measurements match your equipment, because even a slight mismatch will prevent proper sealing.

Common uses for a 25x47x7 mm oil seal include gearboxes, electric motors, centrifugal pumps, speed reducers, and other power transmission equipment. You will also find it in machine tools, conveyors, and process machinery where a shaft turns inside a housing and oil must be kept separate from the surrounding environment. In these setups, the seal works alongside a bearing or bushing, and when it fails, you typically see lubricant leaking out or contamination getting in.

When choosing this seal, consider shaft speed, operating temperature, and the lubricant being used. The A 101 design with spring works well for general applications, but if the equipment sees heavy dirt or water, a seal with an auxiliary lip or dust guard might be a better fit. During installation, coat the lip with the same oil or grease used in the equipment, press it in perpendicular to the shaft using a support tube, and avoid hitting it directly. A lip that is damaged or installed crooked will leak early.

If you need a replacement for the DBH 9217, the easiest approach is to send us the full part number, the shaft, housing, and width dimensions, and a photo of the old seal if you have one. With that information, we can search for a suitable alternative among the brands we carry. We can also advise you if the housing is worn and a repair sleeve might be needed.
