When looking for the best screw that offers accuracy and efficiency, the ball screw is the best for your system. Now, you also do not have to worry about replacing the ball screw when it is broken because fixing it at the ball screw repair service will be quicker and less costly ball screw repair. Using ball screws also more beneficial compared to the pneumatics or hydraulics system because it offers more precision. It can be adjusted within micron accuracy and high linear speed until 2m/s and efficiency are other benefits of the ball screw. Compared to linear guides, ball screw offers higher accuracy and efficiency but the disadvantage is they could suffer from low internal friction that caused back-driven. However, the accuracy up to one-thousandth of an inch per foot from the ball screw shafts gives this particular screw great advantage in your system.
The range from 1 to 150kN of dynamic load ratings generally achieved by industrial ball screw but the operating factors like speed, load and duty cycle could decrease these loads and affecting the lifetime and performance. Radial loads are averse to the lifespan so any load has to be in-line with the screw. When compared to other alternatives, ball screws provide low friction that resulted in high mechanical efficiency by up to 90%. The ball screw could reduce downtime for part replacement and maintenance, at the same time lowering the need for lubrication because of the lack of sliding friction between the screw and nut that accommodates the extended lifespan of the screw parts. The original cost of using a ball screw in your system could be outweighed by the lowered power demands combined with a thorough performance advantage.
One thing you need to pay attention to in the ball screw is the importance of a preloading. This is when between the screw assembly and the ball nut an internal force is applied to cancel free radial and the axial lash. It is also done to reduce backlash, increase rigidity and secures acceptable wear marks in the application.
