The DBH 9740 is a radial shaft seal built to hold lubricant in and keep contaminants out where a shaft turns inside a housing. Its Mx design uses a single spring-loaded lip. Shaft 15.90 mm, housing 25.35 mm, height 6.40 mm, so it fits tight, compact assemblies. Treat it as a wear item: once it starts weeping oil or letting grit past the lip, it is time to replace it.

Reading the code is straightforward. The 9740 designation ties the seal to its size group, and the three figures you need to match are the shaft diameter of 15.90 mm, the housing bore of 25.35 mm and the 6.40 mm height. Mx tells you the lip style: one lip with a spring, meant for lubricated rotating shafts. DBH is a brand we supply, so each seal reaches you with its factory markings intact and traceable to the original reference.

Where you will run into it: gearboxes, pumps, electric motors, compressors and other power transmission equipment with a shaft passing through a housing that has to stay oil- or grease-tight. The same seal shows up in dusty or wet conditions, where the lip keeps particles from working their way in. Agricultural, industrial and transport machinery maintenance is where most of these get changed.

Selection comes down to measurement. Pull the old seal, confirm shaft and housing sizes plus height, and match them to the 9740 figures. Keep the Mx lip type in mind, because orientation matters at installation. If the equipment runs under pressure or at elevated speed, check with us before substituting a different variant. During mounting, coat the lip with lubricant, seat it squarely without hammering the lip, and inspect the shaft for burrs or a worn track that would chew up a new seal.

If the exact 9740 is not what your machine needs, we can search the radial shaft seal range for an equivalent. Send the old part number, or just the three measurements, and we will take it from there. Design variants can also be reviewed when the application calls for it.
