Product Introduction
The Semi-enclosed Ball Screw Linear Unit is a timing belt-driven linear module designed for long-distance high-speed transfer. It adopts a wide high-tension timing belt and dual EGH15CA guide rails, balancing smooth high-speed operation with long-stroke stability. With a rigid body and outstanding load capacity, it meets the linear motion needs of long-distance, high-tempo automation production lines, making it an ideal drive unit for 3C sorting, packaging conveying, warehousing and logistics scenarios.
Key Benefits
▶No performance decay at long stroke
▶Standardized & easy integration
▶High load & rigidity

Why Choose This Machine
The Semi-enclosed Ball Screw Linear Unit adopts an integrally extruded aluminum alloy body with wear-resistant and corrosion-resistant surface oxidation treatment. The timing belt drive requires no oil lubrication, suitable for clean room use. Before delivery, the module undergoes tension calibration and running-in test with stable tension and no slippage, enabling long-term continuous operation and greatly reducing equipment maintenance costs.
Part of Your Smart Factory
Semi-sealed Ball Screw Linear Motion Unit comes with standard industrial interface, perfectly compatible with Industry 4.0 smart production lines and mainstream PLC & motion control systems. Its modular structure allows easy multi-axis combination for gantry and linkage mechanism setup. It supports real-time operation data feedback, fits unmanned production in digital workshops and accelerates flexible line deployment.
FAQ(Frequently Asked Questions)
Q: Can Semi-enclosed Ball Screw Linear Guide be installed in multiple ways such as horizontal, side-mounted and upside-down?
A: Adopting symmetrical rigid structure, it supports horizontal, side and upside-down installation. Only slight load adjustment is needed for different mounting methods without affecting overall operating accuracy.
Q: Will there be synchronization error when multiple Half-sealed Ball Screw Linear Actuator work side by side?
A: Calibrated with unified accuracy before delivery and equipped with matched transmission parts, multiple modules maintain good synchronization during linkage, ideal for multi-station synchronous transfer and gantry frame combination.
Q: Is daily maintenance complicated for belt-driven type? What is its service life?
A: No daily oil lubrication required. It features low wear and loss under normal workshop conditions with long service life within rated load, only simple regular visual inspection is needed.
