The DBH 6263 is a radial shaft seal that sits in the housing bore and works against the rotating shaft, holding lubricant in and keeping dust, water and particles out. Its three reference measurements are a 20 mm shaft, a 48 mm housing bore and a 7.50 mm height, in the Lx design. Sizes like this one show up regularly in pumps, electric motors, gear reducers and other power transmission equipment. MR Industrial Accessories supplies it under the DBH brand.

Reading the number is straightforward once you know the sequence. The 6263 identifies the seal, while the size is written shaft first, then housing, then height: shaft 20 mm, housing 48 mm, width 7.50 mm. The Lx designation tells you it is a single lip seal with a spring, built for lubricated rotating shafts. The elastomeric lip rides on the shaft, the spring holds the lip against it, and the outer body keeps the seal seated in the bore. It belongs to the seals and oil seals group and is treated as a standard replacement item.

You will find this seal wherever a shaft turns inside a crankcase or a box holding oil or grease: centrifugal pumps, electric motors, gear reducers, gearboxes, mixers and conveyors. It also suits positions where dust or splashes are present, since it keeps the lubricant from becoming contaminated. Before fitting a new one, check the condition of both the shaft surface and the housing bore.

Selection comes down to the three dimensions. Measure the shaft, the bore and the height, and compare them with the values above. The Lx design also fixes the lip type and how it faces. If the seal you are removing is a different variant, it is worth confirming before you install anything. When fitting, coat the lip with the same oil or grease used in the equipment, press the seal in squarely to the shaft, and avoid hitting it. A lip that has been damaged or a spring that has lost tension will leak even when the dimensions are right.

For a quote on the 6263, send the dimensions of the old seal and a photo of the part. With that information we can locate the equivalent within the lines we carry. We can also advise you when the housing has a shoulder or the shaft shows wear, situations where a different height or design is sometimes the better choice.
