The DBH 6855Sil radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. With a 25 mm shaft diameter, 52 mm housing and 10 mm height, and Lx design, it is a common replacement part in gearboxes, pumps and power transmission equipment. MR Accesorios Industriales sells it and helps you confirm the size before requesting a quote.

This item is a seal from the DBH line, identified as 6855Sil. Its dimensions are 25.00 mm shaft diameter, 52.00 mm housing diameter and 10.00 mm height. The Lx design indicates a single lip configuration with spring, intended for rotating shafts with lubrication. The elastomeric lip runs on the shaft surface and the outer metal case is fixed by interference in the housing. It is a wear part: over time the lip loses elasticity and oil leakage appears.

It is used in equipment where a shaft rotates inside a housing with lubricant: gearboxes, reducers, centrifugal pumps, electric motors, rollers and mixers. It also appears in applications exposed to dust or splashes, where in addition to retaining oil it must stop the entry of contaminants. In industrial plants and maintenance workshops it is a spare part worth identifying by size so it can be replaced when it starts to seep lubricant or a leak is detected.

To choose the correct seal, first verify the three diameters: shaft, housing and height. Measure the shaft in the contact area with a caliper and check that it has no groove or wear, because a new lip on a worn surface will not seal. Check the condition of the housing and the surface finish. During installation, lubricate the lip with the same oil or grease as the equipment, insert it perpendicular and use a tube or support bushing so as not to deform it. If the shaft is damaged, consider a repair sleeve or an alternative size.
