Planetary Roller Screws – The Best Alternative to Ball Screws
The planetary roller screw is divided into four different structural forms: ◆ Fixed Roller Type Nut Motion Type This form of planetary roller screw consists of the components: long threaded spindle, threaded roller, threaded nut, bearing cap and tooth sleeve. The axial load is transmitted to the ...Read more -
The Development Trend of Linear Guide
With the increase in machine speed, the use of guide rails is also transformed from sliding to rolling. To improve the productivity of machine tools, we must improve the speed of machine tools. As a result, the demand for high-speed ball screws and linear guides is rapidly increasing. 1. high-spe...Read more -
Three Basic Mounting Methods for Ball Screws
Ball screw, belonging to one of the classifications of machine tool bearings, is an ideal machine tool bearing product that can convert rotary motion into linear motion.Ball screw consists of screw, nut, reversing device and ball,and it has the characteristics of high precision, reversibility an...Read more -
Ball Screw and Linear Guide on the Role of High-Speed Processing
1. Ball screw and linear guide positioning accuracy is high When using linear guide, because the friction of linear guide is rolling friction, not only the friction coefficient is reduced to 1/50 of sliding guide, the difference between dynamic friction and static friction also becomes very smal...Read more -
Linear Motor vs. Ball Screw Performance
Speed Comparison In terms of speed, linear motor has a considerable advantage, linear motor speed up to 300m/min, acceleration of 10g; ball screw speed of 120m/min, acceleration of 1.5g. linear motor has a great advantage in the comparison of speed and acceleration, linear motor in the successful...Read more -
