Technical Parameters

High-Accuracy Linear Motion Stage for Automation | Compact Built-in Rail Linear Stage with Micron Precision & High Rigidity

The embedded ball screw linear slide module is an integrated precision mechanical component assembled with linear guide rails, sliders, ball screw transmission system and servo/stepper driving units, dedicated to delivering accurate linear movement for workpieces and tooling. Its core highlight lies in the embedded internal layout: the screw and guide rail are fully housed inside the module body, which can be embedded into machine frames or workbenches to save installation space, while maintaining outstanding structural rigidity and repeat positioning accuracy ranging from ±0.005mm to ±0.02mm.

1. Distinctive Structural Characteristics

Internal Embedded Ball Screw Transmission
Driven by precision ball screws matched tightly with sliding blocks, the screw is entirely embedded within the module housing. External interference is greatly reduced, delivering ultra-stable linear motion and superior positioning precision. Powered by servo or stepper motors, it realizes micron-level positioning accuracy and high transmission efficiency. Compared with belt-driven linear actuators, it trades off maximum travel speed and total stroke length for higher precision and rigidity.
High-precision Integrated Guide Rail Assembly
Equipped with high-rigidity rolling linear guide pairs, rolling friction replaces sliding friction to ensure smooth, jitter-free operation during reciprocating motion. It cuts friction loss effectively and extends the overall service lifespan of the module.
Ultra-compact Integrated Body
The one-piece aluminum alloy housing minimizes overall dimensions, occupying far less space and enabling seamless integration into compact automated machinery and precision devices.
Excellent Dustproof & Oil-proof Sealing System
Adopts fully enclosed sealing structure with stainless steel strip cover and rubber gaskets, blocking dust, cutting debris and oil contamination from entering internal components. The screw and guide rail are well protected to sustain stable long-term performance.
Flexible Multi-direction Mounting Options
Supports top-mounted, bottom-mounted, side-mounted and folded motor installation modes, adapting flexibly to diversified layout requirements of different automation equipment.
Optional High-precision Position Feedback Unit
Premium configurations integrate encoders and position sensors to monitor real-time slide position and motion status, supporting closed-loop control for ultra-precise motion regulation.

2. Technical Principle & Internal Structure Composition

The precise linear movement of the module relies on the coordinated operation of four core systems:

Guide Rail System
High-rigidity ball/roller linear guide rails are embedded and ground inside the body, paired with preloaded sliders to deliver low-resistance, steady linear travel and strong anti-deflection rigidity.
Transmission Mechanism
Two mainstream driving types:
✅ Ball screw drive: Converts rotary motion into linear motion via thread pairs, ideal for high-precision, moderate-to-light load scenarios;
✅ Timing belt drive: Features lightweight design and low noise, suitable for high-speed, short-stroke & light-duty applications.
Driving System
Servo motors or stepper motors are standard matched, combined with encoders to build closed-loop control system, ensuring fast dynamic response and consistent positioning precision. High-end versions adopt linear direct drive motors to eliminate mechanical backlash for extreme precision.
Protective Structure
Whole perimeter dust cover and sealing strips prevent particulate pollution, perfectly applicable to cleanroom environments such as semiconductor workshops.

Compact Built-in Rail Linear Stage

Core Advantages

Built to solve common pain points in traditional linear modules, our embedded screw slide table offers key benefits for your operations:

✅ Space-Saving Efficiency

The slim, compact form factor cuts down installation space requirements, making it ideal for small-scale automation equipment, multi-axis Cartesian robots, and tight production environments where every inch counts.

✅ Enhanced Structural Rigidity

The integrated embedded rail design eliminates the need for separate linear guides, reducing deflection under load and improving overall stability—even during high-speed or high-load operations.

✅ Hassle-Free Assembly & Maintenance

Quick, straightforward installation with direct screw locking cuts assembly time. Maintenance is simplified with external oil injection, eliminating disassembly of protective parts and reducing equipment downtime.

✅ Fast, Reliable Delivery

Standard stroke lengths are kept in stock, ensuring short lead times to keep your projects on schedule without compromising on quality.

✅ Cost-Effective Performance

Unlike traditional ball screw modules that require separate linear guides, our embedded slide table eliminates guide rail costs, delivering reliable precision motion at a lower total project cost.

Ball Screw Linear Module VS Belt Drive Linear Module Comparison

Comparison Dimension	Belt Drive Slide	Ball Screw Slide (Standard)	Core Interpretation & Impact
Speed	Ultra-high speed (2:1-4 m/s). Equipped with a belt for high-speed and efficient movement.	Medium-high speed (usually 0.5-1.5 m/s). Limited by critical speed (longer screw ratio); upper speed limit exists.	Belt drive leads in speed and is the optimal choice for high-speed applications.
Accuracy	Lower precision (repeat positioning accuracy ±0.05mm to ±0.1mm). Prone to belt elasticity, backlash, and tension adjustment.	High precision (repeat positioning accuracy ±0.005mm to ±0.02mm commonly). Ground screw with high rigidity, no need for preload reduction.	The screw provides stable pressure on the belt, eliminating the need for precise positioning.
Load Capacity	Low load (usually several kilograms to tens of kilograms). Subject to limited tensile strength and rigidity.	High load (up to hundreds of kilograms or more). Excellent rigidity of the metal screw structure enables large thrust.	The screw acts as a “heavy lifter,” while the belt is a “sprinter” suited for light loads.
Rigidity	Low rigidity. As a flexible belt component, it may deform under heavy load, causing position deviation or vibration.	High rigidity. Metal screw structure with overall strong structural stability and impact resistance.	Differences in rigidity directly affect motion stability and dynamic response.
Operating Noise	Low noise at low speeds. May produce belt flapping or impact noise at high speeds.	High noise at high speeds. The screw generates characteristic “howling” noise, and the noise intensifies with speed.	Belt drive is preferable for noise-sensitive environments (e.g., laboratories, medical).
Maintenance & Care	Synchronous belt aging, fatigue, require regular inspection and replacement. Short service life.	The screw requires regular lubrication but has minimal wear; maintains long-term precision. Long service life (tens of thousands of hours).	Belt drive maintenance is simpler, ensuring long-term precision performance.
Stroke	Suitable for long strokes (up to 10 meters). Cost does not increase significantly; only longer belts and pulleys are needed.	Long stroke with high difficulty (over 1 meter). The long screw is prone to sagging and shaking, requiring additional support, making processing and installation difficult.	Long strokes are the natural advantage of the belt drive.
Cost	Low cost. Simple structure with standard synchronous belts and pulleys.	High cost. Complex manufacturing processes of high-precision ball screws and nuts.	With cost constraints, the belt drive solution offers significant cost advantages.
