40x40mm Manual Rotary Positioning Stage ±10° Tilt Aluminum Alloy Angle Adjustment Table

Descriptions:
This manual rotary stage is designed for precise angular positioning and fine adjustment in optical experiments, measurement setups, and industrial alignment applications. The compact 40x40mm square table is made from high‑strength aluminum alloy with a black anodized finish for durability and corrosion resistance.
The stage provides smooth, backlash‑free movement with a graduated scale for direct reading. The fine‑adjustment micrometer head allows incremental motion of approximately 1′51″ per division, enabling accurate small‑angle tuning. With a load capacity of 1kgf and a parallelism of 50μm, it offers stable and repeatable positioning for light‑to‑medium duty tasks.
Its low profile (20mm thick) and lightweight construction (0.14kg) make it ideal for space‑constrained setups. Whether used for aligning optical components, adjusting sensors, or calibrating fixtures, this rotary stage delivers reliable performance at an affordable cost.

Features:
Precision manual adjustment – micrometer drive with 1° main scale and ~1′51″ per division for fine tuning
Compact square design – 40x40mm table, 20mm height, fits tight experimental spaces
Durable construction – aluminum alloy body, black anodized surface, wear‑resistant and anti‑corrosive
Smooth movement – low friction guide mechanism ensures stable positioning without play
Moderate load capacity – supports up to 1kgf (≈9.8N) for small components
Good flatness – parallelism within 50μm for reliable reference plane
