The DBH 9643 seal is a radial shaft seal with an A 271 design that is mounted in housings of 57.00 mm diameter and 10.50 mm height. Its function is to retain lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and bushings. It is used in gearboxes, pumps, electric motors and transmission equipment where a shaft rotates inside a fixed housing.

This item is a DBH radial shaft seal identified with part number 9643. According to the data sheet, it corresponds to an A 271 design with a housing of 57.00 mm outer diameter and 10.50 mm height. The shaft data is listed as 0 mm, a value that is not taken as a real mounting dimension: it is confirmed against the manufacturer's data sheet before shipping. The sealing lip and the case material are the usual ones of the DBH line for general service.

Seals of this type are installed in equipment where two environments must be separated: the lubricated interior and the exposed exterior. They appear in gearboxes, centrifugal pumps, motors, spindles, mixers and machine tools. They are also used as a secondary barrier in roller or ball bearings mounted in through housings, especially when the equipment works with dust, chips or process water.

To choose well, verify the housing diameter and the height available in the housing, and that the lip design is compatible with the speed and the type of lubricant. Assembly is done with the seal clean, without hitting the lip, using a tube or shim that rests on the outer ring. It is advisable to lubricate the lip with the same grease or oil as the equipment before inserting the shaft.

If part number 9643 does not match the size you have on the machine, send us the actual housing dimensions, the height and a photo of the old seal. With that data we look for an option within the DBH line or another brand we sell. We also tell you whether the A 271 design is suitable for your application or whether another lip profile is better.
