GTB12A Semi-Enclosed Belt-Driven Linear Module

Standard Environment · Ultra-High Speed · Heavy Duty · Industrial Reliability

The GTB12A is a robust, high-performance belt-driven linear module designed for demanding industrial environments. Featuring a dual-guide rail system and a 400W motor capacity, it excels in applications requiring high speeds up to 2000 mm/s and payloads up to 20 kg over long distances.

Core Technical Features

Extended Stroke Capability: Supports a maximum travel range of up to 3050 mm.
Ultra-High Speed: Optimized for rapid-fire positioning and throughput, reaching speeds up to 2000 mm/s.
Dual-Guide Stability: Utilizes two high-rigidity linear guides for superior moment resistance and stability.
Flexible Motor Orientations: Supports 6 different motor mounting positions including side-folding and upper/lower configurations.
High Rigidity: Constructed with high-strength aluminum profiles to minimize deflection over long spans.
Universal Motor Support: Compatible with 400W AC servo motors from Panasonic, Delta, and Mitsubishi, as well as high-torque stepper motors.
