- 20 kg payload for high-load SCARA work Handles large-component pick-and-place, handling, and mechanical assembly under high-load conditions within an 800 mm reach.
- Double-support X and Y axes Both primary axes use a double-support structure that further enhances rigidity for stable motion under heavy loads.
- Anti-overturning ball screw transmission The combined ball screw transmission increases rigidity in the screw overturning direction by approximately 30% and rotational rigidity by about 70%, while withstanding greater rotational inertia.
- High-precision positioning Repeatability of ±0.025 mm on J1+J2, ±0.01 mm on J3, and ±0.01° on J4 supports precise assembly and placement of large parts.
- Clean internal cable routing Internal wiring eliminates the need for external corrugated tubes, reducing spatial constraints and simplifying deployment.
- Flexible programming and teaching Supports SIASUN's independently developed SN programming software, a teach pendant, a virtual teach pendant, and drag-to-teach operation.
Description
The SIASUN SA20A-20/0.80 is a heavy-payload four-axis SCARA robot from the new-generation SA20A series, rated for 20 kg with an 800 mm reach. The series is characterized by high inertia tolerance, strong rigidity, and high precision: both the X and Y axes use a double-support structure, and a combined ball screw transmission raises rigidity in the screw overturning direction by roughly 30% and rotational rigidity by about 70%, allowing the robot to withstand greater rotational inertia. Repeatability is ±0.025 mm on J1+J2 and ±0.01 mm on J3, and the modular design helps keep maintenance costs low.
These characteristics make the SA20A-20/0.80 well suited to large-component pick-and-place, handling, and mechanical assembly under high-load conditions, such as in lithium battery and automotive parts manufacturing, alongside general sorting and gluing duties. Internal cable routing eliminates external corrugated tubes to reduce spatial constraints during deployment, and operators can program the robot through multiple methods, including SIASUN's independently developed SN programming software, a teach pendant, a virtual teach pendant, and drag-to-teach functionality.

Frequently Asked Questions
The SA20A-20/0.80 is a heavy-payload four-axis SCARA robot from SIASUN's SA20A series. It combines a 20 kg payload and 800 mm reach with high rigidity, high inertia tolerance, and ±0.025 mm repeatability on J1+J2, built on a modular design that helps reduce maintenance costs.
It is widely used for large-component pick-and-place, handling, sorting, gluing, and mechanical assembly under high-load conditions, particularly in lithium battery and automotive parts manufacturing.
Both models share the same 20 kg payload, four-axis SCARA layout, and series design. The difference is the working reach: the SA20A-20/0.80 offers an 800 mm reach, while the SA20A-20/1.00 extends this to 1000 mm for larger work envelopes.
The robot supports multiple programming and teaching methods, including SIASUN's independently developed SN programming software, a physical teach pendant, a virtual teach pendant, and drag-to-teach functionality.
