The DBH 5194 is a radial shaft seal engineered to keep lubricant in and contaminants out of rotating equipment. It fits shafts that turn inside a cylindrical housing, making it a common wear item in gearboxes, pumps, electric motors and similar machinery. This seal has a shaft diameter of 48.42 mm, a housing diameter of 80.11 mm and a height of 9.52 mm, with an A 011 profile.

When you look at the DBH 5194 designation, the 5194 identifies the size within the DBH line, while A 011 describes the lip and profile configuration. The three critical dimensions are 48.42 mm for the shaft (d), 80.11 mm for the housing bore (D) and 9.52 mm for the height (h). These values must match the mating components exactly when you replace a worn seal, so always confirm them against the old part or the equipment manual.

Typical uses include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and transmission equipment. In each case the seal runs against a rotating shaft and forms a barrier that retains oil or grease while blocking dust, water and chips. Because it protects bearings and gears from lubricant loss and contamination, a failed seal can lead to premature damage elsewhere, so it pays to address leaks early.

Selecting a replacement involves more than matching the three dimensions. Check that the shaft surface is within tolerance and free from excessive roughness or wear grooves, since a damaged shaft can cause the lip to leak. Also consider rotation speed, operating temperature and the lubricant in use. During installation, lubricate the lip with the same oil or grease used in service and press the seal in perpendicular to the shaft to avoid distorting the lip.

If you need an equivalent size or a close variant, we can help you evaluate options. In some cases a slightly different seal can be adapted with a sleeve or a machined housing, but that decision should always be reviewed technically. The most practical way to find the right replacement is to send us the 5194 code or the dimensions of your current seal—shaft, housing and height—and we will prepare a quote.
