HIWIN ZKLF are double-direction, two-row axial angular contact ball bearings without a flanged outer ring, designed for screw mounting and sealed with lip seals on both sides (2RS). Particularly suited for mounting ballscrews where a bearing seat has been integrated into the application, the ZKLF series covers a wider range of bore sizes than the ZKLFA, making it the standard choice for most ballscrew support bearing applications.
