Technical Specifications & Performance Parameters:
-
Type: Linear Module with integrated drive (Toothed belt or Ball Rail System depending on configuration; LMM variants feature iron-core or ironless linear motors)
-
Sizes Available: Part of series including sizes 140, 180, 220 mm
-
Repeatability: Up to ± 0.05 mm (standard modules); ± 1.0 µm (Linear Motor Modules LMM)
-
Speed: Up to 5 m/s (LMM)
-
Acceleration: Up to 250 m/s² (LMM)
-
Stroke Length: Up to 9800 mm (depending on size)
-
Load Capacity: High load ratings suitable for large masses; forces up to 2,400 N (LMM)
-
Operating Environment: Designed for industrial environments with resistance to dust/oil (specific IP rating depends on encoder/seal option, typically IP20 for internals, higher with covers)
Material Composition & Structure:
-
Base Profile: Anodized aluminum alloy extrusion
-
Guide Rails: Rexroth high-precision Ball Rail Systems (roller/ball bearing based)
-
Drive Element: Toothed belt (high-performance polyurethane with steel tension members) or direct-drive Linear Motor
-
Carriage: Aluminum machined plate with mounting holes for payloads
-
End Supports: Die-cast aluminum or machined components
Functional Features & Working Principle:
-
Working Principle: Converts rotary motion to linear motion via toothed belt or uses Lorentz force in linear motors to directly drive the carriage along the guide rail without mechanical transmission backlash.
-
Zero-Backlash Direct Drive (LMM): Eliminates mechanical transmission elements (lead screws, gears) for higher stiffness and dynamics.
-
Integrated Design: Pre-assembled, aligned, and lubricated (where applicable) reducing installation effort.
-
Maintenance-Free (LMM): Linear motors require no mechanical contact; ball rails offer long relubrication intervals.
-
Modularity: Compatible with Rexroth’s ecosystem (servo motors, controllers, energy chains).
Application Scenarios:
-
High-precision pick-and-place tasks in electronics and semiconductor manufacturing
-
Automated optical inspection (AOI) systems
-
Handling electronic components and small parts assembly
-
Packaging machinery, printing machinery, and material handling conveyors
-
CNC auxiliary axes and testing equipment
Installation Requirements & Usage Notes:
-
Can be mounted horizontally, vertically, or inclined; consider load/counterweight for vertical use.
-
Ensure mounting surface flatness to prevent torsion on the profile.
-
For toothed belt versions, tension must be checked periodically; avoid excessive radial loads on the carriage.
-
Use appropriate end-of-travel limit switches or soft-stop zones to prevent carriage overrun.
-
Protect open guideways with bellows or covers in dirty environments to prolong life.
