The SMC LEJSH63S7B-1200 LEJS-AC Series Electric Actuator is a high-performance solution designed for precision and efficiency. Featuring a high rigidity slider type ball screw drive and an AC servo motor, this actuator is engineered for demanding applications. Its low-profile design reduces the height dimension by approximately 36%, enhancing stability with a lower center of gravity. Capable of handling a maximum workload of 85 kg, it ensures reliable performance with a positioning repeatability of ±0.02 mm. The actuator supports rapid operations with a maximum acceleration/deceleration of 20000 mm/S². For environments requiring stringent cleanliness, the 11-LEJS model complies with ISO Class 4 (Class 10) standards. It is compatible with a range of drivers, including LECSA, LECSB(-T), LECSC(-T), LECSS, LECSS-T, LECSN-T, and LECY, although some models have been discontinued. This actuator is ideal for applications demanding precision, speed, and cleanliness.
