The DBH 8261 is a radial shaft seal built to keep lubricant in and contaminants out where a shaft turns inside a housing. It follows the A 111 design, a single lip with spring. The three dimensions that identify it are a 66.70 mm shaft, a 101.60 mm housing bore and a 17.40 mm height, so it drops into housings made to that standard size. MR Industrial Accessories LLC supplies this brand and can walk you through picking the right seal for the job.

Reading the reference is straightforward. The 8261 code points to this specific seal, while A 111 describes the lip arrangement: one sealing lip with a spring. The size trio is what you match against your equipment — shaft 66.70 mm, housing bore 101.60 mm, width 17.40 mm. Get those three right and the seal seats properly.

You will find seals like this in gear reducers, centrifugal pumps, electric motors, compressors and belt or chain drives. In every case the job is the same: hold oil or grease inside the housing and block dust, water and particles from getting in. Because the lip runs against the shaft, it wears over time and belongs on your preventive maintenance list, or gets swapped as soon as a leak shows up.

Installation matters as much as the part number. Check that the shaft surface is hard and smooth enough, with no burrs or scratches that could cut the lip. Coat the lip with the same oil or grease the equipment uses before pressing the seal into the housing. The 17.40 mm width has to sit flush with the housing depth. If the housing itself is worn, look at a seal with a sleeve or a different size.
