When you need to keep lubricant in and contaminants out of a rotating shaft assembly, the DBH 1394 radial shaft seal is a direct-fit option. It measures 20 mm at the shaft, 36 mm at the housing and 8.00 mm in height, and it follows design A. You will find seals like this in gearboxes, pumps, motors and other power transmission equipment. MR supplies the DBH line and can help you confirm the right size for your application.

The DBH 1394 is a single-lip radial shaft seal with a metal case, which is what design A indicates. Its three key dimensions are shaft (d) 20 mm, housing (D) 36 mm and height (h) 8.00 mm. The number 1394 is part of the brand's coding system, so once you know the code you can quickly match it to the correct seal. This style of seal works on rotating shafts where oil or grease must be retained and outside particles, water or dust kept away.

You will commonly see this size in gearboxes, centrifugal pumps, electric motors, speed reducers and belt- or chain-driven transmission equipment. It also appears in machine tools, compressors and hydraulic systems. Because the shaft diameter is 20 mm, it fits compact assemblies where space is limited. If you are unsure whether this is the right seal for your unit, the shaft and housing dimensions are the first thing to check.

Proper installation makes a big difference in how long the seal lasts. Inspect the shaft for hardness, surface finish, burrs or scratches that could harm the lip. Apply lubricant to the lip before sliding it into place, and use a tool that presses evenly on the outer diameter—never on the lip itself. The housing bore should be clean and free of dents. If the shaft is worn, you may want to consider a seal with an auxiliary lip.

If you need a different size or an equivalent, just send us the code 1394 or the dimensions of your shaft and housing. We can search for alternatives within the DBH line or from other brands we carry, always matching the dimensions and design type. We can also help you cross-reference with seals from other standards if you provide the equipment's technical data sheet.
