The LEJS is available in a motorless type, permitting the mounting of an AC servo motor other than the standard chosen by SMC.  Shaft coupling and mounting patterns are compatible with 8 servo motor series from 5 manufacturers.  Manufacturers include Mitsubishi, Yaskawa, Sanyo Denki, Omron and Panasonic.

• Body sizes: 40, 63 
• Maximum work load: 85 kg
• Maximum speed: 1200 mm/s (H lead)
• Maximum acceleration: 20,000 mm/s²
• Positioning repeatability: ±0.02 mm
• Stroke range: 200 to 1500 mm in 100 mm increments

The LEJS is the clean room version of SMC's high rigidity slider.  The actuator has built-in vacuum piping with an exhaust port to achieve the ISO Class 4 standard.  The 11-LEJS is available exclusively with an AC servo motor.  The actuator features a substantially wider load mounting platform than the LEFS, supported internally by a double axis linear guide for reduced moment deflection.  The AC servo motor enables higher speed and acceleration, as well as a high-load size 63 model exclusive to LEJ.  The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.
