The DBH 9658 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a housing. Its flexible lip rides against the shaft to hold a dynamic seal. You will find this type of seal in gearboxes, pumps, motors and other power transmission equipment, where it protects bearings and prevents leaks. MR supplies this brand and can help you match the right seal to your application.

The seal carries the DBH designation and code 9658. Its listed dimensions are shaft 73.03 mm, housing 98.45 mm and width 10.40 mm. The A 128 design refers to a particular lip profile and case construction. These figures come from the manufacturer's data sheet and must line up with the shaft and housing on your equipment for the seal to work properly.

Seals like the DBH 9658 appear in gear reducers, centrifugal pumps, electric motors, compressors, mixers and conveyors. They stop oil or grease from escaping and block dust, water and particles from getting in, which would otherwise harm bearings and internal parts. Keeping them in good condition is a practical way to protect machinery reliability and service life.

Proper installation starts with clean shaft and housing surfaces, free of burrs and scratches. Before fitting the seal, coat the lip with the same oil or grease used in service. Press the seal in squarely, applying even force around the outer circumference rather than on the lip. A chamfer on the housing helps with centering. The shaft surface also needs the right hardness and roughness to avoid early lip wear.
