Recirculating Ball Screw
Recirculating ball screws convert rotary motion into precise linear motion through rolling balls, providing smooth movement, high rigidity, and reduced friction for demanding linear positioning systems. We support configurations for CNC equipment, machine tools, automated machinery, and space-constrained applications.

Quality Control for Recirculating Ball Screw
Each recirculating ball screw is inspected across dimensions, accuracy, preload, recirculation, materials, machining, and application requirements to verify reliable motion performance and consistent quality.
Critical screw diameter, lead, overall length, nut dimensions, flange dimensions, mounting holes, and shaft-end features are inspected against approved drawings and specified tolerances.
Screw lead accuracy and linear travel are checked to verify consistent positioning performance across the required travel range.
Screw straightness and radial runout are inspected to control rotational stability and reduce vibration during high-speed operation.
Preload and axial clearance are checked according to the specified configuration to control backlash, rigidity, friction, and running smoothness.
Internal, external, or end-cap ball recirculation is inspected for correct assembly and smooth ball circulation throughout the nut.
Specified axial load, linear speed, RPM, stroke, duty cycle, and mounting conditions are reviewed to ensure the selected screw configuration matches the application.
Steel material and heat-treatment processes are controlled to support the required hardness, wear resistance, and service durability.
Precision-ground screw surfaces are inspected for machining quality and consistency required for smooth rolling contact.
Dust-proof features and protective components are checked to help maintain reliable operation in environments exposed to dust, debris, or foreign substances.
The completed ball screw assembly is checked for dimensions, running condition, appearance, and specified performance requirements before shipment.

FAQ
Q: How does preload affect ball screw operation?
A: Proper preload reduces axial play and improves rigidity, while excessive preload can increase friction, heat generation, and drive torque.
Q: What causes axial play in a recirculating ball screw?
A: Axial play can result from insufficient preload, wear, improper installation, or clearance changes during operation.
Q: How should a ball screw be lubricated?
A: Lubrication should be selected and maintained according to operating speed, load, duty cycle, environment, and the manufacturer's recommended conditions.
Q: Can a recirculating ball screw work with linear guides?
A: Yes, ball screws are commonly paired with linear guides, with the ball screw providing linear transmission while the guide system supports and guides the moving load.
Q: What ball screw components need to be matched during replacement?
A: Replacement should match the screw, nut, mounting dimensions, lead, shaft-end machining, and installation interfaces of the existing system.
Q: How can ball screw noise and vibration be reduced?
A: Correct alignment, adequate lubrication, suitable preload, proper support, and controlled operating conditions help reduce noise and vibration.
Q: Can ball screw and bearing support be sourced together?
A: Yes, we provide ball screws and ball screw bearing supports as part of its linear motion component supply, which can simplify component matching and system procurement.
