The DBH 9002 is a single-lip radial shaft seal built for a 125 mm shaft, a 150 mm housing bore and a 12 mm width. It keeps lubricant where it belongs and keeps dust, water and particles out, which is what protects bearings and bushings from premature wear. The seal is pressed into the housing while its lip runs against the shaft, so getting the size right and installing it correctly is what decides whether the assembly stays leak-free.

This seal belongs to the DBH line and carries the code 9002. Its dimensions are 125 mm shaft, 150 mm housing and 12.00 mm height, and the design is Lx. An Lx seal has a sealing lip with a spring, which is the configuration used on rotating shafts that run with lubrication. The four digits of the 9002 code follow the DBH numbering logic: the first pair gives the housing diameter and the second pair the shaft diameter, both in millimeters. The 12 mm height tells you how much axial room the seal takes up in the cavity.

Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, industrial fans and power transmission equipment. In each case the job is the same: shield the bearings or bushings from contaminants and hold the oil or grease in. You will find them on equipment where the shaft turns at moderate speed and the temperature stays within the range of a standard elastomer, including agricultural machinery and continuous process lines.

When you select a replacement, check the shaft and housing against the real dimensions of the machine and make sure the height fits the cavity depth. The Lx design needs a chamfer at the housing entry so the lip is not damaged on the way in. Coat the lip with the same oil or grease used in the equipment before pressing it, and keep the seal square to the shaft instead of hitting it directly. If the shaft is worn or grooved, a wear sleeve or a different lip position is worth considering.

If you are looking for an equivalent to the 9002, send the full code, the shaft, housing and height measurements, and a photo of the original seal. With that we can search the DBH line or other brands we supply. When the seal sits in an assembly with bearings, we can also check compatibility and point you to the right replacement. You do not need the data sheet on hand; the code is enough to get the inquiry started.
