The DBH 9404 is a radial shaft seal with an Lx profile, sized for a 48 mm shaft, a 78 mm housing bore and an 8 mm height. It combines a primary sealing lip with an additional dust lip, so lubricant stays in and external contamination stays out. This seal is common in gearboxes, pumps, motors and other rotating equipment. MR supplies this brand and can help you confirm the right seal for your assembly.

The DBH 9404 follows the Lx configuration: one lip does the main sealing job and a second lip acts as a barrier against dust and dirt. The outer case is metal, while the sealing element is elastomer; the exact compound should be checked against the manufacturer's data sheet for your operating conditions. It is a standard replacement item for rotating shafts.

You will find this seal in gearboxes, centrifugal pumps, electric motors, compressors, spindles and power transmission units. In each case it keeps oil or grease where it belongs and blocks dust, water and particles from entering. Agricultural machinery, conveyors and hydraulic systems also use it where dependable sealing on a turning shaft is required.

To choose the correct seal, match the three key dimensions: shaft 48 mm, housing 78 mm, height 8.00 mm. The Lx style makes sense when dust or dirt is present, because the extra lip adds protection. When installing, coat the lip with the same lubricant used in the equipment, press it in squarely to the shaft and avoid hitting it. If the shaft is worn or rough, repair it or consider a seal with a wider lip.
