LHA4572 Dual-Rail Dual-Carriage Ball Screw Linear Module for High-Precision Industrial Automation

Dual-Rail Dual-Carriage Structure

The LHA4572 incorporates two parallel high-precision linear guide rails, each fitted with a ball carriages. This four-point contact configuration delivers:

• Superior torsional rigidity— resistance to roll, pitch, and yaw moments is significantly enhanced compared to single-rail alternatives
• Higher load capacity— load forces are distributed across two carriage blocks, reducing contact stress and extending service life
• Improved dynamic stability— minimized vibration and resonance at high speeds and accelerations

Precision Ball Screw Drive

At the heart of the LHA4572 lies a high-precision ball screw with front and rear thread accuracy rated to ±0.05 mm. The recirculating ball nut converts rotary motion into linear motion with minimal friction, enabling:

• Smooth, backlash-free positioning
• High mechanical efficiency (>90%)
• Low heat generation during continuous operation
• Extended maintenance intervals

Aerospace-Grade Aluminum Body

The module's main body is extruded from high-strength 6063-T6 aerospace aluminum alloy using an integrated stamping and molding process. Key benefits include:

• Excellent corrosion and rust resistance
• High structural stability with minimal thermal deformation
• Brushed and polished surface finish that resists dirt accumulation
• Optimized strength-to-weight ratio

1. Durable Construction

Engineered with premium-grade materials and precision-machined components, the LHA4572 is built for continuous industrial duty cycles. The hardened ball screw and raceways ensure long service life with minimal wear.

2. Manufacturer Warranty

Backed by YIDI MOTION's comprehensive manufacturer warranty, every LHA4572 module undergoes rigorous quality inspection — including runout testing, load verification, and repeatability calibration — before shipment.

3. Fast Shipping

Standard stroke configurations are maintained in stock for rapid dispatch, with lead times of 5–7 working days. Custom stroke lengths and special configurations typically ship within 15–20 working days.

4. Silent and Smooth Operation

The precision-ground ball screw combined with preloaded linear guide carriages ensures exceptionally quiet and vibration-free motion. Operating noise is kept to a minimum, making the LHA4572 suitable for noise-sensitive laboratory and cleanroom environments.

5. High Accuracy

With a repeatability of ±0.1 mm ,the LHA4572 delivers consistent, reliable positioning for precision assembly, dispensing, and inspection tasks.

6. Easy Installation

The modular design features standardized mounting interfaces, T-slot extrusion profiles, and pre-drilled carriage mounting holes (8×M5). Integrated sensor mounting slots accommodate M3 proximity switches, enabling fast integration into multi-axis systems without custom fabrication.

The LHA4572 is designed for seamless scalability. Single-axis units can be readily combined into:

• XY gantry systemsfor pick-and-place, dispensing, and laser marking
• XYZ Cartesian robotsfor 3D printing, automated assembly, and material handling
• Cantilever configurationsfor vertical insertion and pressing operations

Standardized coupling interfaces and flexible motor mounting options (left, right, or inline) allow system integrators to configure the LHA4572 to meet specific spatial and performance requirements.

The LHA4572 Dual-Rail Dual-Carriage Ball Screw Linear Module is ideally suited for a broad range of industries and applications:

• Automated Assembly:Precision component insertion, screwdriving, and adhesive dispensing
• Pick-and-Place Robotics:High-speed sorting, packaging, and material transfer
• CNC & Digital Fabrication:CNC routers, engraving machines, and plasma cutters
• 3D Printing & Additive Manufacturing:Large-format gantry 3D printers
• Inspection & Testing:Automated optical inspection (AOI), coordinate measuring, and fatigue testing
• Packaging & Converting:Labeling, filling, sealing, and web guiding
• Educational & Research:University laboratories, prototyping facilities, and R&D centers
• Medical Device Manufacturing:Precision assembly and testing of medical components
