The DBH 9644 seal is a radial shaft seal of A 271 design that is installed in housings of 42.50 mm diameter and 9.00 mm height. Its function is to retain lubricant inside the assembly and stop the entry of dust, water or particles that accelerate the wear of bearings and bushings. It is used in rotating equipment where the shaft rotates inside a fixed housing and a reliable, low-maintenance barrier is required.

This item is a DBH radial shaft seal identified with code 9644. According to the product page data, it corresponds to an A 271 design with a housing of 42.50 mm and a height of 9.00 mm. The shaft diameter is listed as 0 mm, a value that is not taken as a real measurement: in practice, the shaft is defined by the seal seat and is confirmed against the drawing or the original part before quoting. The DBH brand is an official brand that MR distributes.

Radial shaft seals of this type are mounted in gearboxes, pumps, electric motors, rollers and transmission equipment where a shaft rotates inside a housing. They also appear in agricultural machines, conveyors and process equipment. The combination of a 42.50 mm housing and a 9.00 mm height is common in medium-sized assemblies, where the seal must seal without adding unnecessary friction or requiring special machining.

To choose correctly, verify the diameter and condition of the shaft, the diameter and depth of the housing, and the type of lubricant and working temperature. The A 271 design defines the lip profile and the metal body, so it is advisable to respect that geometry. When mounting, lubricate the lip, avoid hitting it and make sure it seats perpendicular to the shaft. If the housing has burrs or the shaft is scratched, the seal will not seal even if the size is correct.

If code 9644 is not the one you are looking for, or you need a neighboring size, send us the original code, the shaft measurement, the housing diameter and the height. With that data we can locate an equivalent seal within the DBH line or another brand we distribute. A photo of the part and the housing, or the assembly drawing, also helps to confirm the design and avoid changes.
