The DBH 6444 is a radial shaft seal in the A 111 design, built to hold lubricant inside a housing and keep dust, water and particles out. Its three key measurements are a 54 mm shaft, a 79.4 mm housing bore and a 19.05 mm width. MR Industrial Accessories supplies this brand and helps maintenance and purchasing teams match the seal to the equipment it protects.
The 6444 designation identifies the size, while A 111 describes how the seal is made: one lip with a spring, running against a rotating shaft that is already lubricated. A metal case holds the elastomer lip in place, and the two parts work as a unit to keep the sealing edge in contact under normal running conditions.
Seals of this size show up in gearboxes, reducers, centrifugal pumps, electric motors, drive shafts and process equipment. In every case the job is the same: keep oil or grease where it belongs and stop outside contamination from getting in. Because the lip wears over time, the seal is a replacement item. Hardening, nicks, deformation or visible lubricant loss are the usual signs that it is time to change it.
Installation calls for a few checks. Confirm that the shaft and bore measure up to the stated figures, make sure the shaft surface is clean and free of burrs, and press the seal in square to the shaft rather than hammering it. Put some lubricant on the lip before it goes in. When you pick a replacement, rotation speed, operating temperature and the fluid being sealed all matter, since they drive the choice of lip compound and spring.
The quickest way to get a quote on a replacement is to send the 6444 code, or to measure your old seal and pass along the shaft, bore and width figures. From there we can search within the same family or propose a compatible design. If the mounting space has room, we can also review whether a different height or lip style would work.
