The DBH 8779Pol is a radial shaft seal built to keep lubricant in and contamination out of rotating equipment. It follows the Lx design and measures 19 mm at the shaft, 30 mm at the housing bore and 5.50 mm in height, so it suits assemblies with very little axial room. MR Industrial Accessories supplies this brand and helps you confirm the correct seal for the job.

Reading the number is straightforward. The 8779Pol code identifies the item, and Lx tells you it is a single-lip seal with a metal case for lubricated rotating shafts. The three figures follow the usual order: shaft 19 mm, housing 30 mm, height 5.50 mm. Because the section is only 5.50 mm tall, this seal fits bores where a thicker profile would not seat properly.

You will find seals of this size in small gearboxes, electric motors, centrifugal pumps, compressors, fans and other power transmission assemblies. The job is always the same: hold oil or grease inside and block dust, water and particles from getting in. Machine tool spindles, conveyors and agricultural equipment running at moderate speeds are also common homes for this size.

Before installing, check three points. Confirm the shaft and housing diameters match the values above, make sure the height clears the space you have, and face the lip toward the fluid side. The shaft surface should be clean and free of burrs or scratches across the contact band, and a light film of lubricant on the lip before pressing it in helps. Even a correctly sized seal will leak if it goes in crooked or runs on a worn shaft.

Looking for a replacement? Send the code 8779Pol together with your shaft, housing and height dimensions, or simply the caliper readings from your equipment. That is enough for us to search the radial shaft seal range for a match, from this brand or another line we carry. If Lx is not the right configuration for your conditions, we will say so and suggest what to evaluate instead.
