The DBH 9688Vit radial shaft seal keeps oil or grease inside a housing while blocking dust, water, and particles from entering. It fits gearboxes, pumps, electric motors, and other power transmission equipment where lubricant must stay contained. With its A 156-R-H design and 28 mm shaft, 42 mm housing, and 5.00 mm height, it suits small-shaft, thin-section applications.

The 9688Vit code reflects a 28 mm shaft diameter, a 42 mm housing bore, and a 5.00 mm overall height. Its A 156-R-H design is a single-lip seal with a metal case and a retaining spring. It presses into the housing and rides against the shaft to form the sealing line. This part belongs to the seals and radial shaft seals range that MR supplies under the DBH brand.

You will find this seal in gearboxes and gearmotors, centrifugal pumps, electric motors, compressors, and power transmission units. It also appears in machine tools, washing equipment, and other systems where shafts run on bearings and lubricant must be retained. Because the lip runs directly on the shaft, check the shaft surface for wear, grooves, or roughness before replacement.

To choose the right seal, confirm that the shaft diameter, housing bore, and height match the equipment. Rotation speed, operating temperature, and the lubricant type all affect lip service life. During installation, lubricate the lip, keep it square to the bore, and press it in without impact. Remove any burrs or grooves on the shaft first.

If you only have the old seal, send the shaft diameter, housing diameter, and height, or a photo of the part. With that information, the team can locate an equivalent in the same series or in another brand we supply. They can also advise whether a different height seal will fit the housing or if a different lip design is preferable.
