The SMC LEJS40S6A-700 LEJS-AC Series Electric Actuator is a high-performance solution designed for precision and efficiency. Featuring a high rigidity slider type ball screw drive, this actuator is powered by an AC servo motor, ensuring reliable and smooth operation. Its low-profile design reduces the height dimension by approximately 36%, making it ideal for applications with space constraints. With a maximum work load capacity of 85 kg and positioning repeatability of ±0.02 mm, it offers exceptional accuracy and stability. The actuator supports a maximum acceleration/deceleration of 20000 mm/S², allowing for rapid and precise movements. Additionally, it meets clean specifications compliant with ISO Class 4 (Class 10) standards, specifically for the 11-LEJS model. Compatible with a range of drivers, including LECSA, LECSB(-T), LECSC(-T), LECSS, LECSS-T, LECSN-T, LECY, and several discontinued models, this actuator is versatile and adaptable to various industrial needs.
