The DBH 9644 oil seal is a radial shaft seal of A 271 design that fits housings with a 42.50 mm diameter and 9.00 mm height. Its job is to keep lubricant inside the assembly and block dust, water or particles that speed up wear on bearings and bushings. It is used in rotating equipment where the shaft turns inside a fixed housing and a reliable, low-maintenance barrier is required.

This item is a DBH radial shaft seal identified by code 9644. According to the product page data, it corresponds to an A 271 design with a 42.50 mm housing bore and 9.00 mm height. 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. DBH is a brand MR sells.

Radial shaft seals of this type are fitted in gearboxes, pumps, electric motors, rollers and power transmission equipment where a shaft rotates inside a housing. They also appear in agricultural machinery, conveyors and process equipment. The combination of a 42.50 mm housing bore and 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, check the shaft diameter and condition, the housing diameter and depth, and the type of lubricant and working temperature. The A 271 design defines the lip profile and the metal case, so it is best to respect that geometry. During installation, lubricate the lip, avoid striking 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, send us the original code, the shaft size, the housing diameter and the height. With that data we can locate an equivalent seal within the DBH line or another brand we carry. A photo of the part and the housing, or the assembly drawing, also helps confirm the design and avoid changes.
