The DBH 1132 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. Its A 369 design and stepped height of 11.00/18.50 mm make it suitable for housings with a shoulder or for covering two mounting positions. It is used in gearboxes, pumps, electric motors and power transmission equipment operating with oil or grease.

This item is a seal from the DBH line, identified with code 1132. According to the product page data, it is mounted on a shaft with a diameter of 40 mm and in a 72 mm housing. The nominal height is 11.00/18.50 mm, which indicates a profile with two height dimensions: one for the seat in the housing and another for the lip or outer dust guard. The A 369 design defines the geometry of the lip and the metal body. It is a radial-type seal, not axial: it seals against the cylindrical surface of the shaft.

Typical applications for a seal of these dimensions appear in rotating equipment where oil must be separated from the environment. Gearboxes, speed reducers, centrifugal pumps, electric motors, fan shafts and conveyor rollers are the most common destinations. It is also found in agricultural and industrial machinery that works with dust or moisture and needs to protect the bearings in the area. The stepped height allows it to be housed in covers with a shoulder or in cavities where the seal must cover a longer section of the shaft.

To properly select a seal, the diameter alone is not enough: you must verify the condition and hardness of the shaft surface, the concentricity of the housing and the type of lubricant. A scratched shaft or one with oval wear means the lip will not seal even if the size is correct. During mounting, lubricate the lip before inserting it, use a support tube so as not to deform it and avoid hitting it from the side. If the equipment operates at high speed or elevated temperature, it is advisable to evaluate a lip compound other than the standard one.

If you need a seal equivalent to the 1132 or a nearby size, send us the code and the shaft and housing dimensions. It also helps if you send us a photo of the old seal or the housing drawing. With that data we look for alternatives within the DBH line or from other brands we carry, always confirming the height dimension and the lip design. You don't need to have the exact number: with the shaft diameter and the outer diameter we can already guide the search.
