For rotating equipment that needs a dependable barrier against lubricant loss and outside contamination, the DBH 6622 radial shaft seal offers a precise fit. It is sized for a 158.75 mm shaft, a 182.55 mm housing bore and a 15.87 mm height, and its Lz design defines the lip and body construction. MR supplies this brand and can help you confirm that the seal matches your application.
The DBH 6622 is a radial shaft seal, a component installed where a shaft passes through a housing. Its role is to keep oil or grease inside the assembly while blocking dust, water and debris from entering. The Lz designation refers to the seal's internal construction, which is intended for rotating service. You will find this type of seal in gearboxes, crankcases, pumps and similar machinery.
Common installations include speed reducers, centrifugal pumps, mixers, heavy machinery and power transmission equipment. In each case, the seal protects adjacent bearings and gears from premature wear caused by lost lubricant or incoming particles. Because the lip also acts as an exclusion element, the DBH 6622 is suitable for environments where dust, chips or moisture are present.
Correct installation starts with clean, damage-free mating surfaces. The shaft and housing bore must match the stated dimensions: shaft 158.75 mm, housing 182.55 mm, width 15.87 mm. For the lip to run properly, the shaft surface typically needs a hardness of at least 45 HRC and a roughness Ra between 0.2 and 0.8 µm. Apply lubricant to the lip, then press the seal in squarely with a suitable tool to avoid distortion.
If you are considering a replacement, MR can help you identify an equivalent from another brand. Provide the original code, the three dimensions or a photo of the part, and we will look for a matching option. For high-speed or high-temperature operation, let us know so we can review the lip material with you.
