The DBH 1309 is a radial shaft seal built to the A 378 design, sized for a 75 mm housing bore with a 10 mm height. Its job on a rotating assembly is straightforward: hold lubricant in and keep dust, water and chips out, which takes the wear off bearings and shaft journals. Maintenance crews run into it on equipment that sees washdown, grit or general plant dirt. We supply it through our seals and oil seals line for repair and scheduled replacement work.

The designation 1309 identifies this radial seal, and the A 378 design covers the lip profile and the elastomer compound behind it. The housing diameter is 75 mm and the overall height is 10 mm. Those two figures are the ones to match when you pull a worn seal and start measuring.

Typical homes for a seal like this include gearboxes, pumps, electric motors, transmission shafts and process equipment. In food, chemical or aggregate plants, where hoses and dust are part of daily operation, a seal in good condition is what keeps bearing grease where it belongs. Agricultural and road machinery maintenance schedules usually list this kind of replacement as a planned shutdown item.

Sizing a shaft seal comes down to three checks: shaft diameter, housing bore and height. Here the 75 mm bore and 10 mm height are fixed. Because the A 378 profile is specific, the bore may need an entry chamfer and the shaft surface should be smooth and free of scoring so the lip is not cut on installation. Coat the lip before pressing it in and use a guide sleeve so the spring stays seated.
