The DBH 9048 is a radial shaft seal built to keep oil or grease where it belongs and to block contaminants from reaching a rotating shaft. Its three governing measurements are a 16 mm shaft, a 25 mm housing bore and a 7.00 mm height. Pressed into the housing, it wipes against the shaft as it turns, which makes it a routine replacement item on gearboxes, pumps, motors and transmission equipment.

Two things define this part: the lip design coded Lx and the size it fits. Read the numbers as shaft 16 mm, housing 25 mm, height 7.00 mm. The elastomer lip rides on the rotating shaft, while the outer body holds tight in the bore. Within the DBH line, designation 9048 points to this particular size, which is why maintenance crews treat the code and the three measurements as interchangeable when ordering.

Wherever a shaft turns and lubricant has to stay put, this seal has a job: gearboxes, centrifugal pumps, electric motors, compressors, line shafts and process equipment, plus conveyors, agricultural machinery and power transmission drives. It works from both directions at once, holding lubricant in and keeping dust, water and particles out so bearings and gears are not worn down ahead of schedule.

Fitting goes better when the shaft is checked first. Look for burrs, scoring or a worn sealing track, and make sure the surface is clean and lightly lubricated before the seal goes in. Press it squarely into the housing rather than driving it in at an angle, and avoid hammer blows that distort the lip. For a replacement, match the 16x25x7 mm size, then confirm the elastomer, the rotation direction and the temperature and speed of the application. A grooved shaft may call for a repair sleeve or a seal with an auxiliary lip.

Quoting is straightforward: send the full code, the dimensions or a photo of the removed part. The team can cross-reference the DBH 9048 against alternatives with comparable characteristics and flag anything unusual about your shaft or housing tolerances. The more detail you provide, the closer the match.

Seals and oil seals are part of the regular range, along with bearings, mounted units and housings, power transmission components, lubrication and maintenance tools. Send code 9048 on WhatsApp or by email and the reply will come back promptly.
