37 x 49 x 8 - Double Lip Oil Seal - ISO

The quality of a bearing arrangement is decisively influenced by the components shaft, housing, seal that are directly adjacent to the bearing.Seals play a decisive role in protecting bearings againstcontamination. If inadequate seals are used, contaminants can penetrate the bearing or an unacceptably large quantity of lubricant may escape from the bearing. Solid contaminants lead to wear and/or fatigue of the raceways and rolling elements. Bearings that are contaminated or running dry will fail long before they reach their fatigue rating life. When designing the bearing arrangement, the use of seals that are correctly matched to the application is decisive in determining the operating life of the bearings.
