THK Standard Lead Precision Ball Screw (Shaft End Finished Product)

High efficiency is obtained because the ball rolls between the screw shaft and the nut, and the driving torque becomes 1/3 or less compared with the conventional sliding screw.Therefore it is easy to change not only the rotary motion to the linear motion but also the linear motion to the rotary motion.Due to the rolling motion by the ball, the starting torque is extremely small, and stick-slip does not occur like sliding motion, so accurate fine feed can be performed.Since there is no backlash and preload is given, axial clearance can be reduced to zero or less by preloading, and high rigidity can be obtained. It has high efficiency and low heat generation, so you can fast-cut. Shaft end, finished product is screw shaft and ball screw nut standardized for space saving standard. The screw shaft standardizes the terminal in conformity with the support unit, and it is made to be a direct connection structure with the motor.Screw shaft, ball screw nut shape is compact design.An appropriate amount of grease is sealed in the ball screw nut. When penetration of foreign matter is considered, it is necessary to completely cover the screw shaft with a dustproof device (bellows etc.).
