The DBH 9711 radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and power transmission equipment where a shaft rotates inside a fixed body. Its A 292 design and its dimensions of 30 mm shaft by 52 mm housing make it a common replacement part in industrial maintenance.

This item is a DBH radial shaft seal identified by code 9711. It corresponds to a 30 mm shaft diameter (d), a 52 mm housing diameter (D) and an A 292 design. The A 292 design defines the geometry of the lip and the body, so it is best to respect it when ordering the replacement.

Seals of this type appear in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. They are also found in machine tools and process lines where a shaft passes through a casing with lubricant inside. In all these cases the function is the same: keep the oil or grease inside and prevent contaminants from entering that accelerate wear on bearings and gears.

To select a seal correctly, you must verify the shaft diameter, the housing diameter and the width of the available space. Rotation speed, working temperature and the type of lubricant also matter, because they define the material of the lip and the body. Installation requires cleaning the shaft, lubricating the lip before inserting it and seating the part perfectly perpendicular so as not to damage the edge. If the shaft has burrs or wear, the new seal will not seal properly.

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

MR Accesorios Industriales carries the DBH brand as part of its line of seals and oil seals. If you already have the code at hand, write to us on WhatsApp and we will quote it. If not, tell us which equipment it is mounted on and what dimensions it needs and we will work it out together.
