The DBH 9643 seal is a radial shaft seal of A 271 design that mounts 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 the wear of 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 code 9643. According to the product page data, 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 measurement: it is confirmed against the manufacturer's data sheet before shipping. The sealing lip and the body 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 correctly, 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. Mounting is done with the seal clean, without hitting the lip, using a tube or spacer 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 code 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 a neighboring size within the DBH line or another brand we distribute. We can also verify whether the A 271 design is suitable for your application or whether another lip profile is better.
MR Accesorios Industriales distributes the DBH brand as part of its line of seals and radial shaft seals. If you need a quote for this code or to ask about an equivalent size, write to us on WhatsApp with code 9643 and the dimensions of your equipment. We will reply with the available alternative and the purchase conditions.
