The DBH 6641Sil is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 22 mm shaft, a 40 mm housing bore, and has a 6.50 mm overall width. The Lz designation refers to the lip and body style. This seal is a common replacement in gearboxes, pumps, and motors.

This seal is identified by the manufacturer code DBH 6641Sil. Its dimensions are shaft 22 mm, housing 40 mm, and width 6.50 mm. The Lz design indicates the lip and seal body configuration. Because of its narrow section, it fits in spaces where axial room is limited. It works as a dynamic seal on a rotating shaft, holding oil or grease in place while blocking dust, water, and other particles.

You will find seals of this size in gearboxes, speed reducers, centrifugal pumps, electric motors, compressors, and power transmission units. They also appear in machine tools, washing equipment, and irrigation systems. In every case, the seal protects the bearings and the lubricant from outside contamination. Since it is a wear part, inspect it whenever you see oil leaks or dirt entering the housing.

When installing a radial shaft seal, make sure the shaft and housing are clean and free of burrs or scratches. Apply the same oil or grease used in the equipment to the lip before pressing the seal in. Insert the seal squarely onto the shaft; avoid hitting the lip directly. Use a tube or spacer that presses on the outer ring. If the housing has a chamfer, follow the correct mounting direction. To select a replacement, compare the shaft diameter, housing bore, width, and lip type with the original part.
