The DBH 6855Sil is a radial shaft seal designed to retain lubricant and exclude dust, water, and other contaminants where a shaft rotates inside a housing. It has a 25 mm shaft diameter, 52 mm housing diameter, and 10 mm height, with an Lx design that denotes a single lip with spring. This seal is commonly used in gearboxes, pumps, and power transmission equipment. MR Industrial Accessories supplies this part and can help you verify the size before you request a quote.

This seal belongs to the DBH line and carries the code 6855Sil. The dimensions are 25.00 mm for the shaft, 52.00 mm for the housing bore, and 10.00 mm for the height. The Lx designation indicates a single lip with a spring, intended for rotating shafts with lubrication. The elastomeric lip runs against the shaft while the outer metal case is held by interference in the housing. As a wear part, the lip eventually loses elasticity and allows oil to seep.

Typical applications include gearboxes, reducers, centrifugal pumps, electric motors, rollers, and mixers—any equipment where a shaft turns inside a lubricated housing. It is also found in environments with dust or splashes, where it must both retain oil and block contaminants. In plants and maintenance shops, identifying the seal by its dimensions makes it easier to replace when leakage appears.

To select the correct seal, confirm the three dimensions: shaft, housing, and height. Measure the shaft in the contact area with a caliper and check for grooves or wear, since a new lip will not seal properly on a damaged surface. Inspect the housing condition and surface finish. During installation, lubricate the lip with the same oil or grease used in the equipment, press it in perpendicular, and use a tube or support bushing to avoid deformation. If the shaft is worn, consider a repair sleeve or an alternative size.

If you cannot find the exact size or the part number does not match the one installed, send us the shaft, housing, and height dimensions, along with a photo of the part and the housing. With that information we can look for an equivalent in the DBH line or other brands we carry. The more details you provide, the faster we can respond.
