THK BNK1404-3RRG2+330LG7Y Ball Screw Finished Shaft Ends Ball Screw

Model: BNK1404-3RRG2+330LG7Y

The ball of THK BNK1404-3RRG2+330LG7Y ball screw rolls between the screw shaft and the nut, which is highly efficient. Compared with the conventional sliding screw, the driving torque of TBNK1404-3RRG2+330LG7Y ball screw is reduced to 1/3 or less. Therefore, not only can rotary motion be converted into linear motion, but also linear motion can be easily converted into rotary motion.

Since the ball is rolling motion, the starting torque is extremely small, and there is no stick-slip like sliding motion, so that THK BNK1404-3RRG2+330LG7Y ball screw can achieve precise micro-feeding.

There is no backlash, and preload can be applied to make the axial clearance zero or less, and the THK BNK1404-3RRG2+330LG7Y ball screw has high rigidity.

With high efficiency and low heat generation, the THK BNK1404-3RRG2+330LG7Y ball screw can achieve high-speed feeding.

The shaft end and finished product are ball screw units, using standardized screw shafts and ball screw nuts to save space.

The screw shaft terminal matches the support unit, adopts a standardized design, and is directly connected to the motor.

The screw shaft and ball screw nut are compactly designed.
