The DBH 9126 is a radial shaft seal that sits on the rotating shaft and seals against the housing bore, keeping lubricant in and contaminants out. Its published dimensions are 34 mm shaft, 50 mm housing and 7.00 mm height, with the Lx design. MR Industrial Accessories supplies this seal within its seals and oil seals range.

The part is identified by the DBH designation 9126. Its published attributes are shaft 34 mm, housing 50 mm, height 7.00 mm and design Lx. In the Lx configuration the seal has one lip with a spring and no outer dust lip, which suits rotating shafts under permanent lubrication. As a brand that MR supplies, DBH parts arrive with their factory marking and traceability.

Seals in this size range turn up in gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain drives. In each case the job is the same: hold the lubricant where it belongs and keep outside contamination away from bearings and gears. Treat it as a wear item. At each preventive maintenance stop, look for a lip that has hardened, cuts, lost elasticity, or a visible leak, and replace the seal when you find them.

Installation starts with the shaft and bore. Check the shaft dimensions and surface finish, and make sure there are no burrs or machining marks; the bore must be clean and undistorted. Apply lubricant to the lip before fitting, then press the seal in with a tube or spacer that pushes on the outer ring rather than the lip. The 7.00 mm height and Lx design set the space you need, so confirm the bore depth and shaft shoulder match before you start.

If your application calls for a dust lip or a seal from a different series, send the part number 9126 or the current shaft, housing and height dimensions, along with a photo or sample of the old seal. With that information we can locate an equivalent in the same brand or another brand while keeping the shaft and housing tolerances in mind. We can also advise when the shaft is worn or the bore has play.

If you are unsure about installation or want the dimensions confirmed against your equipment, include a photo of the part plus the shaft and housing measurements. That helps us come back with the option that fits your application.
