A radial shaft seal from the DBH line, code 9644, built to the A 271 design. It seats in a housing with a 42.50 mm bore and stands 9.00 mm tall, holding lubricant in place while keeping dust, water and grit away from bearings and bushings. Use it wherever a shaft turns inside a fixed housing and you want a barrier that needs little attention.

The reference number for this part is 9644, and the product data lists it under the A 271 design with a 42.50 mm housing bore and a 9.00 mm height. Shaft diameter appears as 0 mm in that data, which is not a usable measurement; the shaft side is set by the seal seat itself, so we confirm it against the drawing or the part being replaced before quoting. DBH is one of the brands we supply.

Seals in this group sit in gearboxes, pumps, electric motors, rollers and power transmission assemblies where a shaft rotates within a housing. You will also find them on conveyors, farm equipment and process machinery. A 42.50 mm bore paired with a 9.00 mm height shows up often in mid-size assemblies, where the seal has to do its job without adding drag or calling for special machining.

Selection comes down to a few checks: shaft diameter and surface condition, housing bore and depth, the lubricant in use and the operating temperature. Because the A 271 design fixes the lip profile and the metal case, that geometry should be respected. On installation, coat the lip, keep from hitting it directly and set the seal square to the shaft. A burr in the housing or a scored shaft will cause leaks even when the size is right.

If 9644 is not the code you need, send the original reference along with shaft size, housing bore and height. That is enough for us to track down an equivalent in the DBH line or in another brand we carry. A photo of the seal and its housing, or the assembly drawing, also helps confirm the design and prevent mismatches.
