The DBH 9425 is a radial shaft lip seal built for rotating shafts. It keeps oil or grease where it belongs inside the housing and keeps dust, water and other particles out. The size code reads 40 mm at the shaft, 85 mm at the housing bore and 8 mm in height, which places it in gearboxes, pumps, motors and similar industrial equipment. MR Industrial Accessories supplies this brand and can help you match the seal to your application.

In the DBH 9425 the designation covers an Lx style seal: a flexible sealing lip carried on a metal outer case. The dimensions break down as shaft 40 mm, housing 85 mm, overall height 8.00 mm. The case presses into the housing bore, while the lip rides against the turning shaft. That contact is what holds lubricant in and contamination out.

Typical installations involve rotary motion where sealing matters: gearboxes, centrifugal pumps, electric motors, compressors, machine tools and transmission assemblies. Dust, chips or moisture around the equipment make the seal even more important, since the bearings and the lubricant behind it need protection. The Lx design handles shafts running at moderate and high speeds.

Selection starts with three checks: shaft, housing and height must match the equipment. The shaft surface should be ground and hard enough that the lip does not wear out early. At assembly, coat the lip with the same oil or grease the machine uses, keep the seal square to the shaft and press it in without hammering. A worn or grooved shaft may call for a different size or a repair sleeve.

If you need an equivalent to the DBH 9425, MR Industrial Accessories can look at alternatives from other brands or special configurations, including a double lip or a material for higher temperatures. Giving the full part number, the dimensions and the working conditions, such as speed, temperature and the fluid being retained, speeds up the quote.
