The DBH 6253 is a radial shaft seal built to keep lubricant where it belongs and to block dust, water and other particles from reaching the bearing cavity. Its designation covers a 19 mm shaft, a 38 mm housing bore and a 7 mm height, with the Lx lip configuration. MR Industrial Accessories supplies this seal as part of its seals and oil seals range for maintenance and repair work.

In the code 6253 you are looking at a radial shaft seal from the DBH line. Read the size as shaft 19.00 mm, housing bore 38.00 mm and height 7.00 mm. The Lx design is a single lip with a spring, made for rotating shafts that run with lubrication. The elastomer lip rides against the shaft while the metal case sits press-fitted in the housing. Treat it as a wear part: it gets replaced once lubricant starts escaping or contaminants begin working their way in.

Seals in this size range turn up in gearboxes, pumps, electric motors, transmission shafts and process equipment, as well as in agricultural machinery, conveyors and power transmission drives where bearings and gears need protection. The compact envelope makes it a common choice where space is tight. When a seal lets go, oil leaves and dust enters, and that combination wears out bearings and bushings faster. That is the reason it deserves a look at every preventive maintenance stop.

Before ordering, confirm that the shaft diameter, housing bore and height match the values on the part you are replacing. The shaft should be clean, with no burrs or deep marks, and the housing should not be deformed. Lubricate the lip before pressing it in and use an installation tool so the lip is not damaged. Peripheral speed, operating temperature and the lubricant in use all affect how long the seal lasts. If any of that is unclear, send us the details and we will help you work through the application.

Looking for an equivalent? Send the complete code, the shaft and housing dimensions, and a photo of the part. With that information we can search for alternatives in the DBH line or in other brands we carry. We can also tell you whether the Lx design suits your equipment or whether a different lip type or material would be a better match, so you do not end up with a seal that does not seal.
