HSFWIN SFNU/SFU Precision Ground Ball Screw Series Internal Return Series Ballscrews
Linear Ball Screw :
Ball screw bearings provide a variety of standardized products for various purposes. It is widely used in machine tools. The circulation modes of balls are circular conduit type, circular device type and end cover type. The pre-pressing modes include positioning pre-pressing (twin-nut mode, positioning pre-pressing mode) and constant pressure pre-pressing. Appropriate types can be selected according to their use. The screw has precision ball screw processed by high precision grinding (accuracy is divided into 6 grades from CO-C7) and cold-rolled ball screw bearing processed by high precision cold rolling (accuracy is divided into 3 grades from C7-C10). In addition, in order to cope with the urgent need of customers for delivery, there are also finished products that have been processed at the end of the shaft, semi-finished products that can be freely processed at the end of the shaft and cold-rolled ball screw bearings. As the peripheral parts of the bearing, the necessary screw support units, nut bearings, locking nuts and so on have also been standardized for users to choose and use.
Preload To generate the inner force inside the ball screw to decrease the clearence and increase the rigidity, a set of one gage ( approximately 2μ ) larger steel balls is filled inside the nut or two nuts which are executing mutual displacement in axial direction.
Preload dynamic torque The dynamic torque required for continuously rotating the screws shaft or the nuts under unload condition and the preload has applied to the ball screws.
