The AC servo version of the LEY rod features an AC servo motor instead of a DC version. The AC servo motor enables higher speed, acceleration, and pushing force, as well as a size 63 model not available in a DC version. The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.

• Body sizes: 25, 32
• Maximum work load: 60 kg (horizontal); 46 kg (vertical)
• Maximum pushing force: 736 N
• Maximum stroke: 500 mm
• Positioning repeatability: ±0.02 mm
• Motor available with either incremental 17-bit or absolute 18-bit encoder

The drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.

• IP5x or IP65 ( option “P” )
• Maximum work load: 80 kg (horizontal); 72 kg (vertical)
• Maximum pushing force: 1910 N
• Maximum stroke: 800 mm
• Positioning repeatability: ±0.02 mm
• Motor available with either incremental 17-bit or absolute 18-bit encoder

The LEY 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: 25, 32, 63
• Maximum pushing force: 1,910 N 
• Maximum speed: 1000 mm/s
• Maximum acceleration: 5,000 mm/s²
• Positioning repeatability: ±0.02 mm
• Stroke range: 30 to 800 mm in 100 mm increments

The 25A- series variations are compatible with secondary battery manufacturing for electronics, automotive, and other vehicle types. Design goals include eliminating copper (Cu) and zinc (Zn) materials where possible, and employing a low dew point grease that retains lubricity even in low manufacturing termpertures. Please note the copper and zinc materials are used for the motors, cables, controllers and drivers.

• Same features and performance as standard LEY
• Stainless steel bolts for construction
• Low dew point grease functional down to -70°C
• Copper and zinc free except for motor, cables, and controller
• Alloy steel rod bearing, replaces bronze bearing
• Non-standard materials for compatibility with secondary/rechargeable battery manufacturing
