Part code DBH 6124 is a radial shaft seal from the DBH line, built to hold lubricant in and keep dust and water out of rotating-shaft equipment. Think of gearboxes, pumps, motors and transmissions: anywhere oil or grease has to stay where it belongs. Its size is given as shaft 50 mm, housing 63.50 mm, height 7.00 mm, with design A 199. MR Industrial Accessories supplies this seal as part of its seals range.

How the code reads: DBH is the line, 6124 is the reference, and the three figures that follow describe the fit. Shaft 50 mm, housing 63.50 mm, height 7.00 mm. Design A 199 is a single lip with a spring, meant for a lubricated rotating shaft. The metal case presses into the bore while the elastomeric lip rides on the shaft, and the seal works by interference between the two. Like any wear part, the lip eventually hardens or scuffs, and that is when lubricant starts to escape.

Where this size shows up: speed reducers, centrifugal pumps, electric motors, compressors and transmission units, plus fan, mixer and conveyor shafts. The job is always the same two-sided one, keeping bearing oil or grease inside and blocking particles, water or steam from getting in. That is why these seals turn up so often in preventive maintenance schedules and in repairs on equipment running in dusty or damp conditions.

Fitting it correctly: inspect the shaft for burrs, splines or a worn contact band, and make sure the bore is clean and undistorted. Wipe the lip with the same oil or grease the equipment uses before you seat it, and drive it in with a tube that presses on the outer edge rather than the lip. If the shaft already shows a groove, an offset lip or a repair sleeve is worth considering. Speed, temperature and the fluid in service all feed into the choice.

Need a substitute? Send the code 6124 or your measured dimensions and the team can look for a match in the same brand or another line. Where there is room, a different height or a double-lip version sometimes works. If anything is unclear, a photo of the old part alongside the shaft and bore measurements settles the reference and helps you avoid a wrong fit.
