A radial shaft seal such as the DBH 8741 keeps lubricant where it belongs and keeps dust, water and other particles out. It seats in the housing and rides against the rotating shaft, so it protects the bearings and gears behind it. The dimensions are shaft 28.60 mm, housing 42.95 mm and height 6.50 mm, with the Mx lip and metal body geometry. MR Industrial Accessories LLC supplies this brand and helps you confirm the right reference for your equipment.

The reference 8741 identifies this seal within the DBH line. Reading the size code is straightforward: the first figure is the shaft diameter it runs on, the second is the bore it presses into, and the third is the overall height. In this case that gives 28.60 mm, 42.95 mm and 6.50 mm. The Mx designation describes how the lip and the metal case are built, which determines how the seal sits in the housing and how it meets the shaft surface. It belongs to the radial seals and oil seals category and is made for continuous duty with lubricant present.

You will find seals of this size in gearboxes, centrifugal pumps, electric motors, rollers and power transmission assemblies. The job is always the same: hold oil or grease inside the unit and stop contaminants from getting in, since those contaminants shorten the life of bearings and gears. The part itself is small and inexpensive relative to the equipment it protects, which is why it is worth matching the size and design correctly.

Before pressing a new seal in, inspect the shaft for burrs, nicks or deep grooves in the contact band, and make sure the housing bore is clean and not deformed. Put a light film of lubricant on the lip, then drive the seal in with a tube or bushing that pushes on the outer diameter only. Never apply force to the lip. If the shaft surface is worn, a wear sleeve is an option. Speed, temperature and the lubricant in use all affect which seal is suitable.

For an equivalent, send the code 8741 or the three measurements — shaft, housing and height — by WhatsApp or email. We check what you send against the manufacturer's data sheet and suggest alternatives in the same category. If the seal sits in an assembly that also uses bearings, housings or transmission components, we can look at the whole picture with you and help you choose. A photo of the old part or caliper readings also work if the code is unreadable.
