The DBH 1322 is a radial shaft seal from the DBH line. It keeps lubricant where it belongs and blocks dust, water and particles from reaching bearings and gears. The housing bore is 28 mm and the overall height is 5 mm. Its A 378 designation points to a single sealing lip with a spring, a common setup for rotating shafts in industrial machinery. MR Industrial Accessories supplies this brand and can help you match the seal to your equipment.

Reading the code helps you confirm the fit. The 1322 designation identifies the seal, while the A 378 design tells you it has a sealing lip and a spring. The published housing diameter is 28 mm and the height is 5 mm. That combination is what you compare against the bore and the space in your housing before ordering.

You will find this type of seal in pumps, electric motors, gearboxes, conveyor belts and power transmission equipment. Its job is to hold oil or grease in and keep contaminants out. Treat it as a wear part: once leakage shows up, or the lip feels hard, cracked or misshapen, replacement is the next step.

Selection starts with three measurements: shaft diameter, housing diameter and height. The shaft surface should be clean, with no burrs or deep scratches, and the housing chamfer should be intact. When installing, coat the lip with the same oil or grease used in the equipment and press it in without hammering the lip. A worn shaft may call for a seal with an offset lip.

For an equivalent, send code 1322 along with your shaft, housing and height dimensions, a photo of the part and the lubricant type. With that we can check the DBH line or other brands we carry. We can also help when the original seal is discontinued or the shaft is worn.
