In order to improve the working accuracy of the feed system, the ball screw mechanism must have a high transmission stiffness. In addition to increasing the stiffness of the ball screw itself, the ball screw mechanism must be designed with a sufficiently rigid support structure and must be installed correctly. The factors that affect the rigidity of the support structure include the stiffness of the bearing seat, the contact area between the bearing seat and the machine structure, and the stiffness of the bearing.
Universal ball screw, using angular contact ball bearings is sufficient. Install the bearings "face to face" on the two supporting shaft ends of the ball screw. If it is a specialized screw rod for special equipment, and if the equipment installation manual requires the use of specialized bearings, then assemble according to the relevant instructions.
In the load bearing capacity of the ball screw, both radial and axial loads exist simultaneously, and consideration should be given to the selection of bearings. Commonly used bearings that can withstand the load simultaneously include angular contact bearings and tapered roller bearings. The former focuses on dry light load and high-speed fields, while the latter focuses on heavy load and low-speed situations. It should be noted that the above two types of bearings are generally used in pairs and installed relative to each other (face to face or back to back), which can limit the axial movement of the screw rod.
Ball screw is well-known for its high efficiency. Tests and quality inspections ensure the product efficiency of over 90%. The superior surface quality of the screw ball, its strict size and the minimal friction between the ball and the track contribute to the remarkable temperature rise. It allows achieving high positioning accuracy thanks to presetting and clearance elimination.
The excellent design and meticulous manufacturing facilitate the reliable and speedy operation over 60M/min with the ball screw drive pair. The absolute rigidity is achieved by using superior materials and eliminating clearance. The ball screw does not show viscous friction that makes it highly reversible. Special dust protection devise is used at the nut end for prolonged service life.
High carbon steel and alloy steel that has the surface hardness HRC62 make the ball screw reliable and durable. They provide a long service life reducing the need for regular maintenance.

Ball screw is a type of mechanical linear actuator that converts rotary motion into linear motion. It is widely used in various industrial machinery such as CNC machining center, CNC lathe, CNC bed, CIC wire cutting machine, CNC drilling machine, gantry milling machine, laser processing equipment, marking machine, CNC engraving machine, drawing machine IC packaging machine, CIC discharge machining machine, CWC grinding machine, glass machinery, textile machinery, woodworking machinery, printing and packaging machinery, petroleum machinery, metallurgical machinery, tobacco machinery.
In addition, ball screw can also be used in electronic machinery, such as robotic arm, testing machinery, measurement equipment, platform, medical equipment, factory automation equipment. Moreover, ball screw can also be used in transmission machinery such as metal heat treatment equipment, nuclear reaction equipment, actuators. In aerospace industry, ball screw can be used in aircraft flap actuator, seat actuator, airport installation equipment, radio antenna actuator, door and window control, medical bed control, parking lot equipment control.
