The DBH 1165 is a radial shaft seal featuring design A 378, sized for a 40 mm housing bore and a 7 mm height. Its job is to keep lubricant where it belongs and to block dust, water, and particles from reaching bearings and shafts. In rotating equipment, a properly specified seal is what keeps contamination out and extends the life of the components around it.

The code 1165 identifies this seal within the DBH radial seal line. From the product data, the housing bore (D) is 40 mm, the height (h) is 7.00 mm, and the design is A 378. The shaft diameter (d) is shown as 0, so before you order, confirm the actual shaft size against the drawing or the old part. This is a precision item that runs in direct contact with both the shaft and the housing.

You will find this seal in gearboxes, pumps, electric motors, conveyor rollers, and other power transmission equipment. It also suits environments where dust, chips, or moisture are present, since the sealing lip stops contaminants from passing through. In a plant or workshop, a healthy seal prevents oil leaks and grease loss that would otherwise damage bearings and gears.

For selection, check that the housing bore and height match the space you have. Design A 378 sets the lip profile and mounting style, so substituting a different design without checking is not advised. When installing, lubricate the lip, avoid hitting it, and make sure the shaft is free of burrs or marks that could cut the seal. Cleaning the housing first helps the seal seat and last longer.

To quote an equivalent, send code 1165 along with the shaft, housing, and height dimensions. A photo of the part or the assembly drawing also works. MR Industrial Accessories reviews the manufacturer's data and suggests compatible options within the same DBH seal line, so you avoid a seal that does not fit or cannot handle the working conditions.
