GWH4008-565-678-C3: 40mm Diameter Ball Screw for CNC Machine
The HOJAMA GWH4008 precision ball screw is a core linear motion component engineered specifically for high-precision, high-load industrial applications, enabling efficient, stable, and precise linear motion output. This ball screw assembly features a double-nut preloaded structure with upper and lower nut segments, precisely connected via locking screws and a clamping plate. This design effectively eliminates axial backlash, providing a solid foundation for high-precision power transmission in equipment. Equipped with side-mounted return tube circulators, it adopts a typical external circulation design, where balls recirculate efficiently through the tubes outside the nut body. This guarantees strong load-bearing capacity while enabling higher operating speeds, making it ideal for high‑dynamic operating conditions. Furthermore, the nut features an integrated square flange on the upper side, complete with multiple pre‑drilled standard mounting holes. This allows for rigid connection to machine tool slides and automated actuators, guaranteeing installation accuracy and enhancing overall operational stability.
Key Performance Advantages
1. High-Precision Positioning: The double-nut axial preloading function enables zero-backlash or minimal-backlash transmission, significantly improving positioning accuracy and repeatability to meet the stringent requirements of the C3 accuracy class, fulfilling the core demands of precision machining and measurement.
2. Efficient & Energy‑Saving Transmission: Based on the rolling friction principle, this ball screw delivers a transmission efficiency of more than 96%, far superior to traditional lead screws. It greatly lowers power consumption while enhancing system responsiveness, making it perfectly suited for high‑speed feed applications.
3. High Load Capacity & Shock Resistance: Featuring an external circulation structure and double-nut configuration, this ball screw with nut delivers excellent resistance to high axial loads and transient impact forces. It ensures stable performance under heavy-duty precision driving conditions, effectively extending the service life of the entire equipment.
Typical Applications
1. CNC Machine Tools: Our ball screw set drives Z-axes and other feed axes in machining centers, CNC lathes, and grinding machines to ensure precision cutting and machining accuracy.
2. High-End Automation & Precision Instruments: The precision ball screw serves automated production lines, precision measuring instruments, and semiconductor manufacturing equipment to achieve micron-level positioning and stable operation.
3. Special Industrial Equipment: Applied to injection molding machines, presses, and similar equipment, the ball screw assembly delivers reliable high-precision linear motion support under heavy-load conditions.
