This item is a DBH 6641Sil radial shaft seal, identified by its manufacturer designation. Its dimensions are 22 mm shaft diameter, 40 mm housing diameter and 6.50 mm height. The Lz design corresponds to the lip and seal body configuration. It is a compact-section seal, intended for spaces where mounting height is limited. It is used to retain oil or grease and, at the same time, act as a barrier against external contaminants.

Typical applications for a seal of these dimensions include gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission equipment. It also appears in machine tools, washing equipment and irrigation systems. In all cases it performs the function of dynamic sealing on a rotating shaft, protecting the bearings and the lubricant in the area. It is a wear part: it should be inspected when there are oil leaks or ingress of dirt.

To install a radial shaft seal, verify that the shaft and housing are clean, free of burrs and marks. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The seal must enter perpendicular to the shaft, without direct blows on the lip; use a tube or spacer that presses on the outer ring. If the housing has a chamfer, respect the mounting direction. To select the replacement, compare shaft diameter, housing diameter, height and lip type with the original part.
