The DBH 9792 is a radial shaft seal that presses into the housing and rides against the rotating shaft. It keeps lubricant in and keeps dust, water and particles out. The Lx design uses a single lip with a spring, which suits rotating shafts that stay lubricated. With a 30 mm shaft, a 42 mm housing bore and an 11 mm height, it fits equipment where axial room is tight but a dependable seal is still required.

The code 9792 belongs to the DBH line of radial shaft seals. Reading the size is straightforward: shaft 30 mm, housing 42 mm, width 11.00 mm. The Lx designation tells you it is a single-lip, spring-loaded profile for permanent-lubrication service. It is a direct replacement part, fitted by pressing the outer edge into the bore while the lip contacts the shaft with light interference.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment running shafts up to 30 mm. The job is always the same: hold oil or grease in place and keep bearings and gears clear of contaminants. You will also find them on agricultural machinery, conveyors and pumping equipment where the shaft turns continuously.

Before installation, check that the shaft diameter sits within the recommended tolerance and that the surface is free of burrs or deep marks. The housing bore should be clean and undistorted. Lubricate the lip, then drive the seal in with a tool that presses on the outer edge, never on the lip itself. If the shaft is worn, an offset-lip seal may be the better choice. Speed, temperature and the fluid being retained all affect selection.

If you need an equivalent or another size, send code 9792 or your current measurements: shaft diameter, housing diameter and height. With those three figures we can locate an alternative within the same radial shaft seal category, from DBH or another brand we supply. We can also tell you whether the Lx design fits your application or whether a different lip type or material makes more sense.

DBH is one of the seal brands we carry as part of our seals and oil seals line.
