SEXGL Ground Ball Screws: Precision-Engineered Motion Control for Demanding Industrial Applications
SEXGL ground ball screws deliver unparalleled accuracy and durability in high-precision automation systems, trusted by global leaders like BYD (EV powertrain assembly) and BOE (LCD panel cutting robots) across North America, Europe, Southeast Asia, and South Korea. Utilizing advanced grinding technology, these screws achieve superior surface finish and geometric consistency, making them ideal for mission-critical applications where precision and reliability are non-negotiable.
Ball screw bearing specifications selection
(1) Determine the positioning accuracy;
(2) Determine the lead of the ball screw bearing by the motor and the speed requirement;
(3) Check the nut size to determine the stroke and related data of the shaft end of the screw bearing;
(4) Determine the average axial force and speed by load and speed distribution (acceleration and deceleration);
(5) Determine the pre-pressure from the average axial force;
(6) Determine the dynamic load rating by life expectancy, axial load and speed;
(7) Determine the outer diameter of the screw bearing and the nut form by the basic dynamic load rating, lead, critical speed, and DmN value limit;
(8) The outer diameter, nut, preload, and load determine the rigidity (machine design);
(9) Ambient temperature, total length of the nut to determine the thermal variation and cumulative lead;
(10)Screw bearing rigidity, thermal variation position to determine the pre-tension;
(11)Maximum machine speed, temperature rise time, and screw bearing specifications determine motor drive torque and specifications.
