HM150BD Double-Shaft Ball Screw Linear Module for Heavy-Load High-Precision Industrial Automation

C7-Grade Precision Ball Screw Drive

The HM150BD utilizes a high-precision C7-grade ball screw with a flanged ball nut, delivering thread accuracy of up to 0.05 mm. The recirculating ball nut converts rotary motion into linear motion with minimal friction and zero backlash. Key drive characteristics include:

• Multiple lead options— available in 2005, 2010, 2020, 2505, and 2510 configurations to optimize speed versus thrust for specific applications
• Flanged ball nut— the flanged nut design provides a large, stable mounting interface with multiple bolt holes for secure attachment to the carriage
• C7 precision grade— precision-ground screw threads ensure consistent, repeatable positioning with ±0.03 mm repeatability across the full stroke range
• Dust and rust protection— the ball screw and nut are protected from dust and contaminants by the module enclosure, extending service life in industrial environments

Dual Bearing-Steel Linear Guide Rails

The HM150BD incorporates two parallel bearing-steel linear guide rails, each equipped with dual ball carriages. This four-point contact configuration provides:

• Eliminated longitudinal clearance— the dual-rail design eliminates longitudinal clearance and minimizes deflection under heavy and eccentric loads
• Superior load capacity— load forces are distributed across four carriage blocks, enabling the 150 kg horizontal and 30 kg vertical load ratings
• Smoother, quieter operation— the preloaded linear guide carriages ensure smooth, vibration-free motion with reduced noise during operation
• High torsional rigidity— the four-point contact geometry provides exceptional resistance to roll, pitch, and yaw moments, maintaining accuracy even under offset loads

Heavy-Duty 150 mm Aluminum Profile with Enclosure

The HM150BD features a robust 150 mm-wide extruded aluminum profile with an integrated dust cover enclosure. The heavy-duty beam provides exceptional structural rigidity, while the removable cover protects internal components from contaminants. Key features include:

• Heavy-duty beam construction— the wide, thick-walled aluminum extrusion minimizes flex and vibration during high-load operation
• Protective enclosure— the full-length dust cover shields the ball screw, guide rails, and carriage from dust, chips, and debris
• Compact end-block design— the overall length equals effective stroke plus 368 mm, with standardized end-block dimensions for consistent integration
• Noise reduction— the enclosure reduces operating noise by containing belt and bearing sound within the module body

Flexible Movable Nut System for Easy Integration

The HM150BD is engineered for practical, flexible installation. Both the side and bottom of the module feature movable nut systems that allow components to be mounted at any position along the beam:

• Side M4 movable nuts— M4 movable nuts on the side of the beam can be positioned anywhere for mounting cable drag chains, sensors, and brackets
• Bottom M6 movable nuts— M6 movable nuts on the bottom of the sliding platform enable flexible and convenient installation of limit switches and home sensors
• Carriage mounting interface— the carriage mounting face features 4×M6 threaded holes on a 171 mm-wide platform with 48 mm hole spacing, providing a stable, standardized mounting interface

This flexibility eliminates the need for drilling or tapping during installation, reducing assembly time and allowing easy reconfiguration as application needs change.

1. Durable Construction

Built with a heavy-duty 150 mm-wide 6063-T6 aluminum extrusion, C7-grade hardened ball screw, and bearing-steel linear guide rails, the HM150BD is engineered for continuous heavy-load industrial duty. The dust-proof enclosure protects internal components from contaminants, significantly extending service life.

2. Manufacturer Warranty

Backed by YIDI MOTION's comprehensive manufacturer warranty, every HM150BD module undergoes rigorous quality inspection — including ball screw runout testing, load verification, repeatability calibration, and guide rail preload checks — before shipment.

3. Fast Shipping

Standard stroke configurations and lead options are maintained in stock for rapid dispatch, with lead times of 5–7 working days. Custom stroke lengths up to 3,000 mm and special configurations typically ship within 15–20 working days.

4. Silent and Smooth Operation

The precision-ground C7 ball screw combined with preloaded dual linear guide carriages and the enclosed housing ensures exceptionally quiet and vibration-free motion. The dual-rail design eliminates longitudinal clearance, providing smooth, consistent movement even under heavy loads.

5. High Accuracy

With a positioning repeatability of ±0.03 mm and C7-grade ball screw thread accuracy of up to 0.05 mm, the HM150BD delivers consistent, reliable positioning for precision machining, assembly, and inspection tasks. The dual-rail architecture ensures accuracy is preserved even under heavy and eccentric loading conditions.

6. Easy Installation

The modular design features standardized carriage mounting holes (4×M6 on a 171 mm face), M4 movable side nuts for drag chain and sensor mounting, M6 movable bottom nuts for limit switch installation, and compatibility with NEMA 34 stepper and servo motors. These features enable fast, flexible integration into multi-axis gantry systems without custom fabrication.

The HM150BD is designed for seamless multi-axis scalability. Its heavy-duty 150 mm profile and 150 kg horizontal load capacity make it an ideal choice as the primary load-bearing axis in large-format gantry systems. Single-axis units can be readily combined into:

• Single-axis— single-axis heavy-load positioning for pressing, lifting, and transfer applications
• Two-axis XY— XY gantry systems for heavy-load pick-and-place, dispensing, and machining
• Three-axis XYZ— XYZ Cartesian robots for heavy-load 3D printing, automated assembly, and material handling
• Gantry systems— gantry and cantilever configurations for large-format routing, cutting, and digital printing

Flexible motor mounting options and a range of ball screw lead configurations (2005 through 2510) allow system integrators to optimize each axis for the specific torque, speed, and thrust requirements of the application.

The HM150BD Double-Shaft Ball Screw Linear Module is ideally suited for heavy-load, high-precision applications across a broad range of industries:

• CNC Machining & Routing:heavy-load CNC routers, engraving machines, milling machines, and plasma cutters requiring rigid, accurate axis motion
• Automated Assembly:precision component insertion, screwdriving, pressing, and dispensing in heavy industrial assembly lines
• Pick-and-Place Robotics:heavy-load sorting, packaging, palletizing, and material transfer systems
• 3D Printing & Additive Manufacturing:large-format gantry 3D printers and additive manufacturing systems requiring heavy print head support
• Inspection & Testing:automated optical inspection (AOI), coordinate measuring, fatigue testing, and precision positioning test rigs
• Packaging & Converting:heavy-duty labeling, filling, sealing, and web guiding equipment
• Material Handling:conveyor transfers, automated storage and retrieval, and heavy-load positioning systems
• Educational & Research:university laboratories, prototyping facilities, and R&D centers requiring high-performance heavy-load motion control
