The DBH 5278 is a radial shaft lip seal built to keep lubricant in and contaminants out where a rotating shaft passes through a housing. It fits a 60 mm shaft, a 90 mm housing bore and a 10 mm height, so it suits medium-section shafts. As a wear item, it is normally replaced once leaks or running noise show up. MR Industrial Accessories LLC supplies it within its seals line.

This seal carries part number 5278 under the DBH brand. Its size designation reads as follows: shaft 60 mm, housing 90 mm, height 10 mm. The stated design is Lx, a specific construction variant within the oil seal range. The part combines an elastomeric lip with a metal case, and it works in rotating service to hold a seal at the point where the shaft exits the housing.

Seals of this size turn up in gearboxes, centrifugal pumps, electric motors, drive shafts and process equipment running 60 mm shafts. In each case the job is twofold: keep oil or grease inside, and block dust, water or particles from getting in. They are common in assemblies where the shaft turns continuously and a dependable barrier against leakage is needed.

Correct selection means checking three things: shaft diameter, housing bore and the height available. Shaft speed, operating temperature and the lubricant in use also come into play. The Lx geometry should be matched when a replacement is ordered. On installation, lubricate the lip, press the seal in squarely to the shaft and avoid impacts that could distort the housing. A worn or burred shaft can shorten the life of a new seal.

For a quote on part number 5278, the simplest route is to send the part number together with the shaft, housing and height dimensions taken from the equipment. With that information we can check alternatives in the same category or from other brands we carry, and advise whether a compatible construction variant should be considered. The more complete the assembly details, the more accurate the proposal.
