The DBH 9711 is a radial shaft seal that keeps lubricant in and contaminants out where a rotating shaft passes through a fixed housing. It fits a 30 mm shaft and a 52 mm housing bore, and follows the A 292 lip and body geometry. Maintenance teams use it in gearboxes, pumps, motors and other power transmission equipment.

The code 9711 identifies a DBH lip seal. Its dimensions are shaft 30 mm, housing 52 mm, and the A 292 design defines the lip profile and body shape. When you order a replacement, it is best to match that design so the seal seats correctly in the housing.

You will find this type of seal in gearboxes, centrifugal pumps, electric motors, rollers and power transmission assemblies. It also appears in machine tools and process lines where a shaft enters a lubricated casing. In every case the job is the same: retain oil or grease and block dust, water and particles that would otherwise speed up wear on bearings and gears.

Selecting the right seal starts with three measurements: shaft diameter, housing bore and the width of the space available. Operating speed, temperature and the lubricant used also matter, because they influence the lip and body material. During installation, clean the shaft, lubricate the lip before pressing it in, and seat the seal perpendicular to the shaft. A shaft with burrs or wear will prevent the new seal from sealing properly.

To quote the 9711, send the shaft, housing and height measurements taken with a caliper, along with a photo of the part. With that information we can look for an equivalent in the DBH line or in another brand we carry, and tell you whether the A 292 design has a direct replacement or whether a dimension needs adjusting. The more details you provide, the faster we can close the quote.

MR Industrial Accessories LLC supplies the DBH brand as part of its seals and oil seals range. If you already have the code, message us on WhatsApp or email and we will prepare your quote. If not, tell us which equipment the seal is mounted on and the dimensions you need, and we will work it out with you.
