The invention relates reduction of vibration, and more particularly concerns a method and apparatus using a bearing mount system for reducing the vibration. A bearing mounting system and method that reduces vibration using a singular annular elastomeric member contained in a substantially enclosed area that includes open area free of elastomeric material. A bearing raceway surface and an adjacent support surface are spaced apart by a predetermined radial gap. The enclosed cross-sectional area is bounded by features on the bearing raceway surface and the supporting surface that could be either the rotating roll or a support shaft. The enclosed area has a depth and a width and includes the radial gap. The viscoelastic deformation of the elastomeric member contained in this enclosed area in conjunction with the amount of open area in the enclosed area, provides a dual stiffness system that reduces or eliminates the excessive vibration that occurs in chucks for textile fiber windups or similar systems, when there is relative movement to reduce the radial gap and the enclosed area containing the radial gap.
