The SMC LEJS63S7B-1000-R2S1H is a high-performance electric actuator from the LEJS-AC Series, featuring a high rigidity slider type ball screw drive powered by an AC servo motor. This actuator is designed with a low-profile and low center of gravity, reducing the height dimension by approximately 36% (32 mm). It supports a maximum workload of 85 kg and offers exceptional positioning repeatability of ±0.02 mm. With a maximum acceleration/deceleration of 20000 mm/S², it ensures rapid and precise movements. The actuator meets clean specifications, complying with ISO Class 4 (Class 10) standards (applicable to 11-LEJS models only). It is compatible with a range of drivers, including LECSA, LECSB(-T), LECSC(-T), LECSS, LECSS-T, LECSN-T, LECY, and several discontinued models. This makes it a versatile choice for various industrial applications requiring precision and reliability.
