The DBH 6741 is a radial shaft seal built to keep lubricant where it belongs and to block dust, water and other contaminants from reaching rotating parts. Its dimensions are shaft 40.00 mm, housing 84.00 mm and height 12.00 mm, with an Lz design. The seal is pressed into the housing and its lip rides against the turning shaft, which makes it a frequent replacement item on pumps, gearboxes and motors.

Construction-wise, this is a lip seal with an elastomeric body rated for contact with oils and greases, and it normally carries a spring that keeps the lip pressed against the shaft. The Lz designation describes a particular lip and body geometry. Together, these elements allow the seal to hold up under continuous rotation.

You will find seals like the DBH 6741 in gearboxes, centrifugal pumps, compressors, electric motors and power transmission assemblies. There, the job is always the same: hold the oil or grease inside and keep dust, water or particles away from the bearings. Fan, mixer and conveyor shafts also use them, including in dirty or damp environments. When this part fails, bearing and gear damage usually follows, so it matters for equipment reliability.

When selecting a replacement, confirm that your housing bore and shaft match the 40.00 mm and 84.00 mm figures, and that the housing depth accepts the 12.00 mm height. Because the Lz design is a specific geometry, a different original design should be checked with us before you swap it in. At installation, coat the lip with lubricant, keep burrs away from it, and check the shaft for splines or heavy wear.
