Angular contact ball screw support bearing 20TAC47 20x47x15mm
Information:
◆ Ball screw bearings 20TAC47 are ideal products for converting rotary motion into linear motion or converting linear motion into rotary motion.
◆ Ball screw consists of screw, nut and ball. Its function is to convert rotational motion into linear motion, which is the further extension and development of the ball screw. The significance of this development is to change the bearing from a sliding motion to a rolling motion. Due to the small frictional resistance, ball screw bearings are widely used in various industrial equipment and precision instruments. The
◆ Ball screw bearings 20TAC47 are the most commonly used transmission elements in power tools and precision machinery. Their main function is to convert rotational motion into linear motion, or to convert torque into axial reversal force, while simultaneously achieving high precision, reversibility and High efficiency features.
