The Linear Stage Block 3″×3″ is a precision single-axis positioning platform engineered for controlled linear motion in mechanical systems requiring high repeatability and smooth travel. Built on aluminum construction with single-row ball bearings and side-drive actuation, this stage delivers stable platform positioning with minimal friction and angular deviation. The 3″×3″ platform accommodates standard 1/4-20 threaded mounting and accepts various modular actuators (sold separately) via relocatable mounting blocks, enabling left or right-handed operation without modification.

– Key Features
• Precision ball bearing construction eliminates friction-induced drift and ensures smooth travel across the full 46 mm range
• Hardened carbide insert engages actuator tip for repeatable contact and extended component life
• Spring preload system removes backlash from the drive interface without influencing load measurements
• Non-influencing lock mechanism provides stable positioning and prevents unintended stage movement
• Side-drive configuration simplifies actuator integration and accommodates industry-standard micrometer heads such as the SM-50 (1" range)
• Symmetrical design allows reconfiguration for opposing drive orientations without hardware changes
– Typical Applications
• Precision component positioning in automated assembly and test systems
• Robotics and industrial motion control requiring <200 µrad angular stability
• Optical alignment and beam-steering platforms with repeatable accuracy
• Laboratory instrumentation where thermal drift and backlash must be minimized
– Compatibility & Integration
The stage accepts external actuators through relocatable mounting blocks, enabling integration with various drive mechanisms. Recommended accessories include adjustment screws (AJS100-2) and micrometer drives (SM-50). Linear guides with dual-block systems integrate with this platform for multi-axis configurations. Load capacity performance is maintained across standard ball screw and belt drive systems when properly installed.
