A radial shaft seal in the DBH line, the DBH 9662 is a single-lip, spring-loaded design that keeps lubricant inside a housing and keeps dust and moisture out. Its working dimensions are 70 mm at the shaft, 90 mm at the housing bore and 13.50 mm in height, and it carries the designation A 184. Maintenance and purchasing teams order it by code for gearboxes, pumps, motors and similar rotating equipment.

Reading the number: 9662 is the size reference inside the DBH range, while A 184 describes the lip configuration. The 70 mm figure is the shaft diameter the lip rides on, 90 mm is the bore the outer case presses into, and 13.50 mm is the overall height. Confirm all three against the worn part or the housing drawing before ordering, and check that the bore depth leaves room for the case to seat squarely.

Because the seal is a standard metric size, it turns up in gearboxes, centrifugal pumps, electric motors, rollers, fans, mixers and other power transmission assemblies. In each case the job is the same: hold the oil or grease in place and shield the bearings or bushings behind it from outside contamination. Equipment from many different builders uses this size, so the code is often enough to identify a replacement.

Design A 184, a single lip with a spring, suits rotating shafts running at moderate speed and low pressure. Inspect the shaft surface first; burrs, grooves or heavy wear will damage a new lip quickly. Coat the lip with the same oil or grease the equipment uses, then press the seal in perpendicular to the housing, using a flat driver rather than hammer blows that could distort the case.

If the original seal is no longer readable, work from the measured dimensions instead of the code. Send the 9662 reference, or the shaft, bore and height you measured, and the team can point to a matching seal and suggest equivalents. Unusual shaft or housing tolerances are also worth mentioning, since they affect how the seal fits.
